Using calipers, using them OFTEN, is when you become VERY accurate with them. Back in the 50-60's was a common method, and "not surprisingly" accurate., but expected. Now you blokes are showing an even higher level of production.
You know as old as it is hearing about the virus it’s actually kind of refreshing to hear from a normal guy like the rest of us without a political spin on it.
Hi peter your video was great !!!, as far as the flu goes I live on Long Island and the hospitals are jammed , they are setting up tent cities on the football field of the college by my house . The island is a ghost town !!! . I hope it doesn’t get to Houston, be well!!!
I don’t understand why you people in America are underestimating this, This is real, In Australia we have been in full lockdown for over a month now, look at the stats, you guys are screwed. I do love this channel, and many like yours, but I’m afraid many of you American guys aren’t going to make it. I hope I’m wrong, and god bless from Australia.
i was thinking the same. finland is not hit very badly yet but i dont want to risk anything. i read a news article that said usa have optimistic death toll of like 200k.
I'm not saying I'm not taking this seriously. Remember the figures they are using are depending on a software model whose developer already came out and said his original figures for USA around 2,000,000 and for Britten 500,000 were incorrect. So their software models are not giving them correct information. But than again what else can they do. They just don't have any history to base this on. I think the best thing to do is for people to take care of themselves and be careful how they treat their own bodies to keep up their immune response. In the end that may be all you have to see you thru.
This is all turning into arm chair quarterbacking. After the fact. Corporate America, has farmed out so much stuff out of the United States, that it can’t hardly even produce a mask to protect themselves. Politicians and corporations asked for this and they’ve got it. It’s amazing that some people don’t believe factual data. Hard for me to believe anything. But when corporations farmed it all out. Theirs nothing left. It doesn’t matter what country you’re in
The end result is impressive! Educational to see how something like this can be put into a process with repeatable, accurate results. The magnet to mark indexed tools inspires.
I apologize for being late, but I hope you had a great Birthday! I am not a machinist, but a mechanical person. You are a true pleasure to watch in your videos. My entertainment is to watch machining videos and appreciate the talent you and others display! Blessings!
really interesting to see the tooling from previous videos in action. just how you described it would run. excellent work.stay healthy and help keep others healthy.
It's funny. I never really thought of any of the things our governments are asking us to do (I'm in Ontario, Canada) as "giving up liberties". I certainly don't think any of it is permanent. My biggest concern is for the health care system. If the virus gets too far out of hand and the system is overwhelmed it can do long-term damage to the system. And so I am happy to do what I can to help the situation. Offering another perspective. Happy broaching!
@@jacobsonconstruction The most important one. Speech and the right to indiscriminately offend with it in particular. But you obviously you either don't think you have or don't care.
@@Steve_Just_Steve Yes, you're right. I don't think that I have given up freedom of speech. I do care about it though. I'm not sure I agree with "indiscriminate offense" as an essential right. It's true that someone somewhere may be offended by something that you or I say, but that is more an effect of freedom of speech itself, isn't it? Indiscriminate offense may do more damage to freedom of speech in the long run, because people like to complain about being offended, and then want to clamp down on speech freedoms. I still believe in the power of good manners;) I don't think we need to offend one another for offense's own sake. Interesting discussion anyway, for a broaching video!
@@jacobsonconstruction I agree about the power of good manners. But with all do respect, I'm not sure you do care or perhaps understand it with statements such as " I'm not sure I agree with "indiscriminate offense" as an essential right" and "because people like to complain about being offended". Firstly offense is taken not given; secondly there is no right not to be offended. I am certainly no JP fanboy but to quote him "Because in order to be able to think, you have to risk being offensive." which is from the Channel 4 Cathy Newman interview. May I ask if you've seen that particular interview? I'd probably save me a lot of typing. lol ; )
You did an amazing job explain the sub program you wrote for the broaching. Have always struggled getting my head around repeated subroutines and the way you laid it out really broke through. Great video bud and all the best!
When I started learning CNC I refused to learn CAM until I felt like I conquered g code. I spent two years in school doing it and 6 month at an extremely technical shop. I'll never regret it. Now I program at a shop that has large basic shaped, yet heavy precise cutting technical parts but the jobs don't really change. I like the technical side of this niche operation and how difficult it is but I wish I had more variety of work.
Watching Peter measuring with a spring caliper caliper was delightful! Also that's a very interest case for making and using a go-nogo gauge as the bore diameter and the key height is an internal feature (in Greek that's called trima -τρήμα- ...if anyone cares) while the key width is a male feature (or axonas -άξονας-). So the gauge would have an OD on the minimum bore tolerance, the key slot in the maximum depth or a flat to OD of ODmin-KeyHmax and a the width of the slot to the maximum tolerance of the key width.
Happy Birthday Peter! Don't know about your exact part of the world, but things in a lot of places haven't worked out too well over the past three months. My birthday too, this week. Hope we both have a good, healthy year ahead of us. Best wishes to you and your family
In Australia we’re are in lock down with curtain essential services aloud to operate as normal, I agree with your thoughts and am concerned with the models put out by government specialist, all falling well short off expected targets, I’m guessing it’s better to be safe than sorry, love your work and stay safe.
It seems there needs to be some math put to covid-19. Since I live in Vancouver, I’m going to use the lower mainland, pop 3 million to illustrate. The Vancouver area is excellent because it is a self contained population between the sea, mountains & US border. The first case of covid19 confirmed in Vancouver was Jan 31. A bit of context is needed for this date: this is the date the provincial government made public the confirmation of a positive result from the lab in Winnipeg Manitoba. One can easily imagine the time lag for from the patient presenting themselves to their family physician & the health care system overcoming of the ‘it can’t happen in Canada’ inertia to get this test. But I’m gong to be an optimist & say this was instant; the patient rocked up with the symptoms & the diagnosis was instant. So let’s do some simple math based on 2 assumptions: you can be contagious for 2 weeks before symptoms & in living a normal life you infect 5 random people per day. These assumptions seem reasonable; BC didn’t go into lock down until Mar 16 & the choir incident demonstrates how infectious this disease is. Lots of opportunity to pass the virus at work, grocery shopping, picking up your kids from school, buying gas for your car, going to yoga. Just normal living. Under this pathology & scenario, by March 12, 4 days before the Vancouver lockdown 24 million people are infected. That is 8 times the population of Vancouver. All from just one seed patient. An increase in the seeds just linearily increased the number. Oh, this doesn’t account for the people flying in & out of Vancouver International airport nor the across border traffic. But this is worse than that; the Vancouver patient zero has no known association with China: no friends/family/travel. They got it from someone else in Vancouver that wasn’t sick enough to go to the doctor but was happily spreading the virus. The whole cycle started before patient zero’s first contagion date of Jan 17. Walking back patient zero’s contact put that date at Jan 03. This raises a lot of questions chief of which are: - Has the majority of the population of the lower mainland been infected since mid March?? - is the pathology wrong? - why did it take so long to get into the at risk population? Enjoy your show, R Gardhouse B Sc, AME (Retired), B Eng, P Eng (Retired)
Hi Pete, glad u guys are ok. Just went to Costco here in Bozeman, MT and seemed normal traffic, maybe a little lighter then normal. Maybe 10-15 were wearing masks. "Those who would give up essential liberties, to purchase a little short term safety, deserve neither liberty nor safety." Ben Franklin
Peter: To start out thanks for the great content you provide. You truly have a lot of talent in the machining arsenal to share. Thanks for that. On the part about not much has changed I disagree. I have family in and around the River Oaks area of Houston and they tell me a very different story!
So I'm sitting here late night watching this key cutting and think wow that's pornographic. Then the coolant starts ... I literally fell out of my chair.
It will catch up to your city Peter, this will be shock to the social system. They will have to stay indoors like the rest of the world.....Nice video as always
Thanks for the video ... currently on 'lock down' in the UK so this sort of content is a god send ... and the 'political' aspect? ... in general our NHS is a much loved and treasured institution ... we are self isolating not to save ourselves but to avoid our care system being overwhelmed ... hopefully preventing many thousands of our fellow citizen dying unnecessarily ... its not that we are being 'forced'' to do it by the government ... more that its just ... 'the right thing to do'
I didn't say isolation wasn't necessary during these times. I'm just concerned what this could lead to. I have already seen aspects of discrimination relating to these things. I don't think things will go back to "Normal" after this. We shall see. We actually have no choice.
Please take care and be safe. The attitude you describe (I’m not by any means health expert) “takin it easy” is maybe the reason why USA has the most cases. Now to see yet another great video of yours.
I agree completely with you about how the governments of the world are taking very extreme measures, but no one knows exactly what the economic and social effects will be. People loosing their jobs in great numbers can cause more devastation than the actual virus. Domestic violence, depression, alcoholism drug abuse crime and the list goes on. Seems like the government is going in blind with it all. Ps: another very interesting video, thanks from Australia. Stay safe 👍🏻
The broaching 'technology' is really neat , and it shows why certain features have a high price and a lot of cycle time , you just can't spit out a part every minute as many would think . What's the cycle time on that key feature , not just the broaching but roughing included ? On the virus matter , i have no idea what to say , but the one thing that i see with my own eyes is that people that are supposedly the most exposed are the most stubborn ones . Where i live we have a sorta kinda lockdown. You should not be outside without a just case , and the smallest fine is more than a minimum wage . The gowernment says they do this to stop the spread and protect the elderly..... . That's great and all that , but the old folk does not listen and as a result the working class gets hours cut , unemployment . A lot of 'non essential' people are out of work for a certain period(every bar/pub/restaurant/malls - that's a lot jobs) . So while the working class that provides to the economy gets fucked, the old people get to act cocky and stubborn. I would very much like to see pensions cut in an equal matter (and over some poverty threshold of course). It's just not fair. I won't even go to the religion part.............
Hey, Peter just like in your video about cutting this key, you stayed away and checked your results, it's the same with corona, New Zealand, South Korea and Australia tested everyone and if you were positive you were Quarantined, if negative you could go to work, none of us have micrometer eyes so we're always checking and measuring our work and perfecting our processes till we're sure it repeats, I don't understand how anyone can make a decision until we've taken measurements and know what we're dealing with, feelings aren't facts, so until we know for sure we're guessing and hoping for the best, by the way I liked your video and the tip with the caliper and jo blocks, peace
Great and informative video as always. Would it be possible to use a touch probe to measure this feature more easily and accurately? It seems to me that probing could make measuring many of your more complicated part features easier. Thank you and stay safe.
Someone else mentioned this and it is possible. But my probe styli combination won't reach into the location. It would be very tight the way the probing cycles work. To tell the truth I hadn't thought of doing it that way. I may think about trying this if I can find a stylist that could be long enough and fit in there. the sphere on the end of the one I have on the probe is to large (6MM) and it's length is to short.
Большое спасибо. Для меня очень важны и нужны Ваши видео, Ваше время, потраченное на его создание. Огромное Вам спасибо за потраченое на меня и таких как я ваше время. Всё у Нас будет хорошо! Пандемия будет преодолена, мы все будем вместе жить на нашей планете Земля. Очень трудно объяснить людям что они все едины, все из крови и плоти, все похожи один на одного, не зависимо от цвета кожи, цвета и разреза глаз, от возраста и пола. Может быть это знание нам очень дорого достаётся, может быть. Но может нет другого способа объяснить это нам? Может после этого Мы будем более внимательны друг к другу и поймём, что у нас одна на всех планета Земля? Храни Вас Бог. Будьте здоровы. Thank you very much. Your videos are very important and necessary for me, your time spent on its creation. Thank you so much for your time spent on me and people like me. Everything will be fine with us! The pandemic will be overcome, we will all live together on our planet Earth. It is very difficult to explain to people that they are all one, all of blood and flesh, all look alike, regardless of skin color, color and section of the eyes, age or gender. Maybe this knowledge is very expensive for us, maybe. But maybe there is no other way to explain this to us? Maybe after that we will be more attentive to each other and understand that we have one planet Earth on all? God bless you. Be healthy.
That is a possibility but it’s to far back for my probe. And it would be very tight for a probing cycle. But it could be done with the proper stylist. Not a bad idea.
@@EdgePrecision understood. FYI I bought a broach for my mill/turn from Dumont. They provided a parametric macro for running it. Amazingly it was probably worth more than the broach. Maybe it'll help someone know this... thanks
Awesome video as usual. That Go Gauge, did you make that, just based on drawing tolerances? Does it just split the tolerances, or MMC? Would be interesting to learn a little about making that gauge.
# AvE This precision machining and methodology is Jaw Dropping Awesome! On a lighter note, I wonder how this video commentary would have turned out if AvE had this size of tool using a broaching action, carrying a copious volume of pressurized moose milk ejecting from the inner diameter of the hole with every stroke (huge smile). AvE, you have corrupted our pure machinist thoughts! Again, your precision machining and quality control is NASA quality work. Only Respect, and a little fun. Thank You.
I can't speak for everyone else but I'd much rather see content from you that you deeply understand (like the explanation of the G gode towards the end of the video) than content that you clearly have no understanding of (like the stuff at the beginning of the video). The former is literally why I subscribe to your channel. I feel like every time you set out to explain exactly what you're doing you apologize for doing so. You are among the most competent CNC machinists making videos. There's nothing to apologize for... well except that glare and washout on the yellow notepad, that didn't work out so great.
@@experimental_av - Or, perhaps, we are free to voice opinions in response so there can be a discussion. You can just skip those if you don't want to see them :)
Will it be used? I’m not sure what you are referring to? These are real parts that will be used and paid for. Or are you asking where will it be used? These are for the petro chem industry.
a few years later but now I have to broach a part, I knew you made a video about it. I'm also going to make a subprogram. thank you and keep up your videos
Hi Peter, an ardent follower of yours from India. Excellent video, as usual, I must concur. And regarding CV thing, we feel we've been very lucky in India so far. No. of infections yet to reach 5 digits (thankfully, and hoping we don't reach there)... Fingers crossed for now. Take care of your health !
Thanks for all the extra work making the video. Is it possible to have different tool offsets for the same tool but in different sub programs used in the same program? I didn't notice you having to call the offset in the sub-program.
My screen shot didn't show the upper part of the main program where the offset for the tool first tool is called. There is actually two sections of the program that I ran in the video. The first tool does the back side and returns up to the tool change position.Than stops with a M01. Than it calls the second offset/tool (Same tool just rotated 180) and comes down to do the front side of the key. So this tool is running two offsets and tool setups (The orientation angle). The offset and tool information is called up than the tool is positioned to the start of where the sub program starts than retracts up and away after for each, Front and back. I should have made that more clear in the video. Hope that makes sense.
I think the words you're looking for @3:20 Peter are "a calamitous authoritarian power grab". You're awesome Peter, hope you continue to give your thoughts on current events along with the BEST machining content on YT. Thx buddy.
@@59jm24 Oh totally, the power grab is already happening. It is 50/50 IMO there is even an election that will happen this year. And the Gov't doesn't care about the pea shooters the public has and are in fact happy to perpetuate that little delusion of power. They have militarized the police force so far off the deep end that many city police forces have armored vehicles now. If you are not a tRumpinski loyalist you are being run out of washington, and he has destroyed the constitution and constructed his own "acting" government structure. Its a similar repeating history to the german gov't of the 30's, like the CV19 is similar to the 1918 pandemic. Here is a spotlight on the playbook that just used the CV19 to seat another dictator.

Thank you for your intro. I agree with every word you say. We are crossing a line and can never go back. We will never know if it really served any purpose compared to the way we have always reacted in the past. So we will plan future policy on one data point which is essentially invalid as there is no real comparison or control. Pretty scary indeed!!
What I said I did with the hope it would make people think about just blindly following without giving a thought to what was sacrificed for what they have and enjoy. A week and a half ago to many it seemed a little far fetched. Now it seems a little closer to reality. And I’m sorry to say I think it will get worse yet. I thank all for their comments. All comments are welcome. This is one of our freedoms that’s under attack. Look at the protest in Michigan just today. We already have lost the right to assemble.
Peter, We just had 2 deaths in a senior home in their mid 90's, made it through the depression, battles in Europe and the Pacific, but they couldn't battle this virus, along with other seniors in this home, You're worried about your freedoms?
Peter, I am a constitutionalist and libertarian, and am a "I'll never let you take my freedoms" kind of person. I also have degrees in chemistry/biochemistry, and almost another in microbiology. I have done a lot of work with virology, epidemiology, and microbiology. (Outside of "normal curriculum" school work.) I told my parents the first week of January that this virus will bring our country to its knees. I know far too much about viral pathology to be coaxed by fear mongering or politics, but this needs to be taken seriously. It's not the virus you have to worry about, as the death rate from the virus is very low. (The rate it is so high is because people that would have otherwise survived the virus, are dying because of a lack in available healthcare. Hospitals don't have the staff, supplies, equipment to deal with all these people.) Last time I was in the hospital, years ago, in a large hospital, in a large metropolitan area, I was in a hospital bed in the hallway the whole time. The hospital was so over crowded that all 75 rooms in the wrong were full with 2 people to a room, and flanking the two sides of the ball way were beds end to end with another 36 people. They were crowded them and they're even more crowded now. And people forget that this virus is IN ADDITION TO influenza and every other reason people are normally hospitalized. People that would sit in the hospital for 5 days and get better, are dying because of it. Also, there have been lots of confirmed stories of people being pronounced dead due to COVID-19 from infection by SARS-CoV-2, who DID NOT DIE FROM COVID-19. Some were never tested, some had been tested but had not received results back (but were still listed as dying from COVID-19 before knowing the results), some died of other reasons, and some are outright lies, like the infant that died in Connecticut. (The governor said that the infant was "the first infant death in Connecticut _related to_ COVID." It was not COVID-19, and the governor knew that. It does of SIDS, but had the virus in its system and was ASYMPTOMATIC. He knowingly LIED. There are hundreds of cases of someone dying, and the CoD lists "complications due to COVOD-19," but have absolutely nothing to do with COVID. The whole problem is those people in Wal-Marts and other stores, acting like nothing is going on. That is the whole thing that is going to cause us to lose our freedoms; people not taking it seriously for whatever reason. SARS-CoV-2 is highly virulent (much more so than _Influenzavirus),_ and it's going to spread like wildfire. The problem is that people are often ignorant to how viruses work and the epidemiology of the diseases they cause. Even idiot physicians are still prescribing antibiotics when someone comes in and has the flu, or even worse, prescribing an antiviral to someone who is young/healthy. So, please take it seriously, and it's only going to get worse. Also, due to cities/states/countries/whole continents are vastly under reporting the number infected. Some are doing it deliberately, or because they don't have testing access, or because they don't have enough test kits and lands to perform the tests, and some just because they lack healthcare and medical statistics altogether. (Like Africa. People were saying, "WOW, we're seeing almost no cases out of Africa." Duh, do you think a continent where 90% of the population doesn't have access to healthcare, is being tested? And do you think there's someone to keep track of those numbers even if they were treated? Ummm, no.)
I hope you don’t think I not taking this seriously. After all I’m in the higher risk age group. I think right now the best thing people can do now is take care of themselves. Do the things to keep their immunity response high. Eat right get plenty of sleep exercise if possible. Things like smoking drinking and other unhealthy things are you enemy right now. We’re probably all going to experience this virus in some way we should give ourselves the best chance. I don’t think the hospital is going to be a option. In fact it may be a good place to get it. I feel for the doctors and nurses. There putting themselves in real danger for their lives.
@@EdgePrecision Oh, I know you're not, and you didn't convey that. You have the same fears about losing freedoms that I do. I just was more putting that out there for everyone. You're the man, Peter.
@@EdgePrecision The number one thing anyone can do is... isolate. Don't breathe the same air as anyone unless you have to, wear a mask if you do, don't go near other people for at least a couple of months. Rest and healthy habits are great, but this virus has killed healthy 25 year olds, it's just less likely to do that than kill old folks. The only safety is in isolation.
Hi Peter! Could you please explain why you choose aluminium for the setup part, over e.g., cheaper steel? And secondly, how are you dealing with the differences in cutting forces and deflection between aluminium and the final material? Thanks, Hansi
Can't speak for him, but in the shop I work in we typically use aluminum because we have a lot of it and it won't damage or really wear tools cutting it at the speeds and feeds were using for whatever we're practicing for. That said we only practice when were making complicated parts from expensive material, so the cost of the aluminum is negligible.
I will add that the price of aluminum and steel doesn't turn out to be that much different. You buy material by the weight in these larger pieces. Now steel weighs almost three times what aluminum weighs .2833 pounds per cubic inch aluminum weighs around .1 pound per cubic inch. so the aluminum could be almost three time more expensive by weight and not cost any more. And also all the reasons Bill Mielke says.
@@EdgePrecision and Bill Mielke: Thanks for your replies and the explanation! Just checked at a local metal supply, and indeed, _by_volume_ aluminium is only slightly more expensive for small quantities and less than 2x the price than the cheapest steel. On the other hand, stainless and tool steel are 2x-5x as expensive as aluminium. :-O Interestingly, PE and POM are the same price as cheap steel (again, by volume). Nice greetings and best wishes from the locked down Austria, even having to wear masks in supermarkets since today. Bye, Hansi
I'm old school and work only with hand operated equipment. I know nothing about g-code, but the way you explained it made perfect sense. Once set up how many units were in the order and is it an order that gets repeated?
This particular part? There are sixteen of them. But each part takes around three weeks to machine complete. So that in itself is around eleven months of work. On this machine.
I've enjoyed your videos for a couple years now and i've always found them to be helpful and insightful. I've been running a hurco vmx42 for the last 8 months straight out of school and we have just received a mazak vtc-300c that i have been volunteered to run. Are there any resources that you know of that would be helpful in learning the control and getting this machine making chips? Happy birthday and i wish you many more.
With regards to the parts your machining in the horizontal. How many parts do you get per insert change/rotation per cutter? Seems like a lot of the same cutters in that tool changer.
There are sixteen parts. Any time you send a part to a outside process there is a chance of misalignment or worse. And besides I would rather get paid for it than the EDM shop.
@@EdgePrecision How does the "or worse" part work with an outside shop? Is there some sort of "Insurance" in the contract If they muck up (what looks to be) a five figure part?
"United We Stand, Divided For All" I am choosing to EXERCISE my freedom to keep my distance from others and limit contact as much as possible, because I care about the lives of others. If being asked to change your behavior and make a sacrifice in order to save your neighbor's lives and reduce suffering feels like a loss of freedom, maybe it's time to take a good look at how you choose to use the freedom that was secured for you by people dying and suffering and sacrificing so that we could live safe and comfortable lives. I am over in the Bay Area, the first mandatory shelter in place area in the US, and very few people are complaining about it, and most are glad that they are safe from the sick people coughing down their neck. In many places the people are demanding such restrictions. Oregon and Washington for instance, the governors were not wanting to order shelter in place, but everyone was watching California, and seeing how well it worked, and public fury finally got loud enough that Oregon and Washington made the order, and almost everyone is happy to follow the distancing rules, some because they are afraid of getting it, but there is a powerful grass roots uprising of people doing it to protect others, and lots of activity on social media supporting each other and encouraging everyone to stay home to save the lives of others, and it's working. And sadly, like Italy, too many people and places are not doing it or taking it seriously until lots of cases in their area, and it's too late already. The Bay Area got it pretty early, and it's working. California followed suit soon after the Bay Area started spiking, and so the rest of the state started distancing BEFORE the case count spiked, and most of it is staying very low as a result. If you aren't surrounded by sick people, it may not make as much sense, and by the time you are, well, ask Italy, or the British PM how well hoping it would go away worked for them. And I know you were just wanting us to think about it, and I appreciate that you have been doing your part, and since you don't really have much contact with people I don't see continuing to work to really be much of a risk, but I am just sharing my thoughts on the freedom side of things, as someone who likes freedom lol
Esprit can do a manual tool path on geometry which simulate ok but this only works if your post processor supports it. Its a bear to loop so I sometimes use it to generate my first moves of gcode with safe start and end blocks for hand editing. You might be able to copy translate the path once it's on screen. Custom cycle will drop handwritten code in as well on the last page but again the post needs to use it. I've used a combination of the two to get around not having the probing package when I need it in a hurry. I'm using Esprit 2020 and factory posts right now.
Thx Peter nice vid! FWIW I don't mind a little thoughtful societal discourse even realizing some of the comments it will generate. I also see the trolls made it here. Anyway, so on the part you are feeding it "radially" as it is broaching but on the tool you are using Cartesian coordinates? I guess that makes sense why you can get the bore next to the key smooth, as I think about it.
Thanks Peter for your very informative and educating videos. The pencil drawing on yellow paper was too difficult to see and understand hope to see a computer simulating one day. The offset compensation could that wave been easier if you have grind the two inserts, so the where aligned properly. Ofcause the insert coating will be removed, but you are running the inserts very gentle when broaching. I've another tip when you use the gundrill and you don't want to scratch the bore that already is machined, you had that situation in another video, you could try to spay the gundrill on the side with Teflon coating. Keep safe and again thanks.
Can I ask you a question? What did you watch the video on a Phone, Pad, or Computer. I keep forgetting that people may be watching these videos on something other than a computer with a high resolution screen. When editing the video it was clear to me but if you could tell me it gives me more information on whet people actually see. Thanks.
@@EdgePrecision It was my Ipad normal size, but I'll give it a try on my laptop not much better 14" screen or maybe my eyes are not the best anymore turning 54 years soon.
Yeah I'm working 12hr days atm. 8 at work and 4 at home programming to prevent crossover between shifts. Hundreds of hours worth of work on the shelves, Guess were in the lucky 'essential' class.
nicely done.. going on the assumption your tool came out correctly could the initial work offset been off a little in the y+ giving you a little more material in the x on the far side... i probably would have screwed myself chasing that haha. Almost paid up on my gantry style lathe (5 years) and i have still not posted a program, all hand written, post for it is still out of my budget.
Great video as always. you sure do amazing work. I agree with your point about considering every action very vcarefully, before you take it. People that are panic'd often will do anything to avoid a perceived bad outcome. However, here are some numbers you might want to consider. Houston has about 2.313 Million people and 19300 hospital beds. About 20% of everyone who contracts the virus needs hospitalization. If everyone gets sick around the same time, you will need 462,000 hospital beds! In Italy, the doctors are having to decide who gets to live or die because they don't have enough beds, ventilators, medicine, so they choose who gets treatment, based on who is most likely to survive. People that are most likely to need this help are 50+, like you and I. The point of staying home is to slow the number of people who get sick all at once, so that the 19300 beds you have will never be overfilled. Also, lets not forget that some of the hospital staff are going to get sick as well. You are a clearly a really smart guy and make a lot of very valid points, but consider the numbers and check them. Don't trust me. Please stay safe and healthy.
Agreed, if you are on a ventilator or dead freedom is pretty much academic concept. I like you don't like the Gov't telling me what I can and cannot do. Like the ole Janis Joplin songs says, "Freedom is just another word for nothing left to loose" . Let's stay healthy for now.
Sorry for all the questions. You mentioned you got the tool in the start position with the CAM software before running the broaching sub-program. Do you need to allow for the tool offset when deciding where to start, what I mean is, is the start point on the generous side to ensure the 1/8 corner radius is completely machined away despite the tool offset being moved a few times?
I think it's great you're willing to think independently about the tradeoffs, and are courageous enough to share your thoughts. That's freedom that can't be taken away. To me, the thing that's unique about a situation like this is that the only solution is (almost) 100% community action. That's a hard thing to reconcile with individual liberties. We've been in other situations where we were willing to sacrifice a percentage of the population to maintain liberty, and did. But in those situations we chose who to sacrifice, a virus won't spare the politicians' sons.
When G91 is commanded it a modal command. A modal command stays in effect until it is changed or reset for all following lines in the program. So in this case the whole sub program is in incremental mode. It doesn’t have to be on every line.
I don't think the "Let it burn" method of dealing with a pandemic is a wise one. There are two problems #1 people can have it for ~10 days prior to showing symptoms (so effectively everyone should assume they have it and act appropriately) #2 there are people that are asymptomatic in that they can get it and have it and never show symptoms (if we look at the first 10 days they have it prior to showing symptoms and the next 14 days they have but don't feel sick that's 24 days they could be spreading) I see Texas working it's way up the chart, currently at 9,247 cases so far. What is the magic number to become SIP concerned? People shouldn't need their gov to tell them what to do. There have been studies that strongly suggest that going about business as usual tends to have a much higher economic cost than long term SIP.
16,638 cases for Texas on 18-Apr-2020. That's about 5,500 cases in nine days; six-hundred-plus additional cases a day. You're correct: business as usual is not the wise choice. It could totally collapse the economy.
Excellent video as always, a perfect length. When the program exits the sub-program does it revert back to absolute positioning if it's in that mode, automatically?
Stay safe, wear a mask, start away from people and you'll be fine! The problem with collective problems is that there's no individual solution -- we need to apply our ability to collaborate for the good of everyone. Once it's over, we'll all be back outside. Also: shaping with a form tool on a lathe? Sweet!
Using calipers, using them OFTEN, is when you become VERY accurate with them. Back in the 50-60's was a common method, and "not surprisingly" accurate., but expected.
Now you blokes are showing an even higher level of production.
You know as old as it is hearing about the virus it’s actually kind of refreshing to hear from a normal guy like the rest of us without a political spin on it.
I appreciate your thoughts Peter
Hi peter your video was great !!!, as far as the flu goes I live on Long Island and the hospitals are jammed , they are setting up tent cities on the football field of the college by my house . The island is a ghost town !!! . I hope it doesn’t get to Houston, be well!!!
I don’t understand why you people in America are underestimating this, This is real, In Australia we have been in full lockdown for over a month now, look at the stats, you guys are screwed. I do love this channel, and many like yours, but I’m afraid many of you American guys aren’t going to make it. I hope I’m wrong, and god bless from Australia.
i was thinking the same. finland is not hit very badly yet but i dont want to risk anything. i read a news article that said usa have optimistic death toll of like 200k.
I would go so far to say it’s as simple as cleaning your hands and cover your mouth when you cough.
I'm not saying I'm not taking this seriously. Remember the figures they are using are depending on a software model whose developer already came out and said his original figures for USA around 2,000,000 and for Britten 500,000 were incorrect. So their software models are not giving them correct information. But than again what else can they do. They just don't have any history to base this on. I think the best thing to do is for people to take care of themselves and be careful how they treat their own bodies to keep up their immune response. In the end that may be all you have to see you thru.
This is all turning into arm chair quarterbacking. After the fact. Corporate America, has farmed out so much stuff out of the United States, that it can’t hardly even produce a mask to protect themselves. Politicians and corporations asked for this and they’ve got it. It’s amazing that some people don’t believe factual data. Hard for me to believe anything. But when corporations farmed it all out. Theirs nothing left. It doesn’t matter what country you’re in
The end result is impressive! Educational to see how something like this can be put into a process with repeatable, accurate results. The magnet to mark indexed tools inspires.
Quarantined here. Your videos are better than a giant sized bottle of valium. Thank you.
I remember welding keys into some aluminum connectors for you back in the '90s. I think it was Mark or Pat that would send them to me. Nice work.
I apologize for being late, but I hope you had a great Birthday! I am not a machinist, but a mechanical person. You are a true pleasure to watch in your videos. My entertainment is to watch machining videos and appreciate the talent you and others display! Blessings!
really interesting to see the tooling from previous videos in action. just how you described it would run. excellent work.stay healthy and help keep others healthy.
It's funny. I never really thought of any of the things our governments are asking us to do (I'm in Ontario, Canada) as "giving up liberties". I certainly don't think any of it is permanent. My biggest concern is for the health care system. If the virus gets too far out of hand and the system is overwhelmed it can do long-term damage to the system. And so I am happy to do what I can to help the situation. Offering another perspective. Happy broaching!
Not surprising, you guys already gave up the most important one.
@@Steve_Just_Steve Ok, I'll bite. Which one is that?
@@jacobsonconstruction The most important one. Speech and the right to indiscriminately offend with it in particular. But you obviously you either don't think you have or don't care.
@@Steve_Just_Steve Yes, you're right. I don't think that I have given up freedom of speech. I do care about it though. I'm not sure I agree with "indiscriminate offense" as an essential right. It's true that someone somewhere may be offended by something that you or I say, but that is more an effect of freedom of speech itself, isn't it? Indiscriminate offense may do more damage to freedom of speech in the long run, because people like to complain about being offended, and then want to clamp down on speech freedoms. I still believe in the power of good manners;) I don't think we need to offend one another for offense's own sake. Interesting discussion anyway, for a broaching video!
@@jacobsonconstruction I agree about the power of good manners. But with all do respect, I'm not sure you do care or perhaps understand it with statements such as " I'm not sure I agree with "indiscriminate offense" as an essential right" and "because people like to complain about being offended". Firstly offense is taken not given; secondly there is no right not to be offended. I am certainly no JP fanboy but to quote him "Because in order to be able to think, you have to risk being offensive." which is from the Channel 4 Cathy Newman interview. May I ask if you've seen that particular interview? I'd probably save me a lot of typing. lol ; )
You did an amazing job explain the sub program you wrote for the broaching. Have always struggled getting my head around repeated subroutines and the way you laid it out really broke through. Great video bud and all the best!
When I started learning CNC I refused to learn CAM until I felt like I conquered g code. I spent two years in school doing it and 6 month at an extremely technical shop. I'll never regret it. Now I program at a shop that has large basic shaped, yet heavy precise cutting technical parts but the jobs don't really change. I like the technical side of this niche operation and how difficult it is but I wish I had more variety of work.
Watching Peter measuring with a spring caliper caliper was delightful! Also that's a very interest case for making and using a go-nogo gauge as the bore diameter and the key height is an internal feature (in Greek that's called trima -τρήμα- ...if anyone cares) while the key width is a male feature (or axonas -άξονας-). So the gauge would have an OD on the minimum bore tolerance, the key slot in the maximum depth or a flat to OD of ODmin-KeyHmax and a the width of the slot to the maximum tolerance of the key width.
Happy Birthday Peter! Don't know about your exact part of the world, but things in a lot of places haven't worked out too well over the past three months. My birthday too, this week. Hope we both have a good, healthy year ahead of us. Best wishes to you and your family
Thanks Thad. ALB Peter.
In Australia we’re are in lock down with curtain essential services aloud to operate as normal, I agree with your thoughts and am concerned with the models put out by government specialist, all falling well short off expected targets, I’m guessing it’s better to be safe than sorry, love your work and stay safe.
Cnc machining videos , programing and tips never gets boring.
It seems there needs to be some math put to covid-19.
Since I live in Vancouver, I’m going to use the lower mainland, pop 3 million to illustrate. The Vancouver area is excellent because it is a self contained population between the sea, mountains & US border.
The first case of covid19 confirmed in Vancouver was Jan 31. A bit of context is needed for this date: this is the date the provincial government made public the confirmation of a positive result from the lab in Winnipeg Manitoba. One can easily imagine the time lag for from the patient presenting themselves to their family physician & the health care system overcoming of the ‘it can’t happen in Canada’ inertia to get this test.
But I’m gong to be an optimist & say this was instant; the patient rocked up with the symptoms & the diagnosis was instant.
So let’s do some simple math based on 2 assumptions: you can be contagious for 2 weeks before symptoms & in living a normal life you infect 5 random people per day. These assumptions seem reasonable; BC didn’t go into lock down until Mar 16 & the choir incident demonstrates how infectious this disease is. Lots of opportunity to pass the virus at work, grocery shopping, picking up your kids from school, buying gas for your car, going to yoga. Just normal living.
Under this pathology & scenario, by March 12, 4 days before the Vancouver lockdown 24 million people are infected. That is 8 times the population of Vancouver. All from just one seed patient. An increase in the seeds just linearily increased the number. Oh, this doesn’t account for the people flying in & out of Vancouver International airport nor the across border traffic.
But this is worse than that; the Vancouver patient zero has no known association with China: no friends/family/travel. They got it from someone else in Vancouver that wasn’t sick enough to go to the doctor but was happily spreading the virus. The whole cycle started before patient zero’s first contagion date of Jan 17. Walking back patient zero’s contact put that date at Jan 03.
This raises a lot of questions chief of which are:
- Has the majority of the population of the lower mainland been infected since mid March??
- is the pathology wrong?
- why did it take so long to get into the at risk population?
Enjoy your show,

Hi Pete, glad u guys are ok. Just went to Costco here in Bozeman, MT and seemed normal traffic, maybe a little lighter then normal. Maybe 10-15 were wearing masks. "Those who would give up essential liberties, to purchase a little short term safety, deserve neither liberty nor safety." Ben Franklin
Excellent quote
Bloody hell mate, you are a wizard at CNC!
Peter: To start out thanks for the great content you provide. You truly have a lot of talent in the machining arsenal to share. Thanks for that. On the part about not much has changed I disagree. I have family in and around the River Oaks area of Houston and they tell me a very different story!
So I'm sitting here late night watching this key cutting and think wow that's pornographic. Then the coolant starts ... I literally fell out of my chair.
xD
Awesome program. Stay safe and healthy.
Nice work Peter! Stay safe brother.
ATB, Robin
Thanks Robin. You too.
I enjoy the heck out of watching your videos!!! You got it going on!!!
It will catch up to your city Peter, this will be shock to the social system. They will have to stay indoors like the rest of the world.....Nice video as always
And they say that math doesn't serve much of a purpose anymore . Great video. Stay healthly
Your G Code explantion made perfect sense for me. I quite often hand code my home made CNC Lathe in a similar fashion. Kind Regards. Chris
Thanks for the video ... currently on 'lock down' in the UK so this sort of content is a god send ... and the 'political' aspect? ... in general our NHS is a much loved and treasured institution ... we are self isolating not to save ourselves but to avoid our care system being overwhelmed ... hopefully preventing many thousands of our fellow citizen dying unnecessarily ... its not that we are being 'forced'' to do it by the government ... more that its just ... 'the right thing to do'
I didn't say isolation wasn't necessary during these times. I'm just concerned what this could lead to. I have already seen aspects of discrimination relating to these things. I don't think things will go back to "Normal" after this. We shall see. We actually have no choice.
@@EdgePrecision ... good luck y'all ...
You are right on the money when u say we are giving up more than we want to.... Statement of the century...times a thousand
Please take care and be safe. The attitude you describe (I’m not by any means health expert) “takin it easy” is maybe the reason why USA has the most cases. Now to see yet another great video of yours.
I agree completely with you about how the governments of the world are taking very extreme measures, but no one knows exactly what the economic and social effects will be. People loosing their jobs in great numbers can cause more devastation than the actual virus. Domestic violence, depression, alcoholism drug abuse crime and the list goes on. Seems like the government is going in blind with it all. Ps: another very interesting video, thanks from Australia. Stay safe 👍🏻
The broaching 'technology' is really neat , and it shows why certain features have a high price and a lot of cycle time , you just can't spit out a part every minute as many would think . What's the cycle time on that key feature , not just the broaching but roughing included ?
On the virus matter , i have no idea what to say , but the one thing that i see with my own eyes is that people that are supposedly the most exposed are the most stubborn ones . Where i live we have a sorta kinda lockdown. You should not be outside without a just case , and the smallest fine is more than a minimum wage . The gowernment says they do this to stop the spread and protect the elderly..... . That's great and all that , but the old folk does not listen and as a result the working class gets hours cut , unemployment . A lot of 'non essential' people are out of work for a certain period(every bar/pub/restaurant/malls - that's a lot jobs) . So while the working class that provides to the economy gets fucked, the old people get to act cocky and stubborn. I would very much like to see pensions cut in an equal matter (and over some poverty threshold of course). It's just not fair. I won't even go to the religion part.............
Hey, Peter just like in your video about cutting this key, you stayed away and checked your results, it's the same with corona, New Zealand, South Korea and Australia tested everyone and if you were positive you were Quarantined, if negative you could go to work, none of us have micrometer eyes so we're always checking and measuring our work and perfecting our processes till we're sure it repeats, I don't understand how anyone can make a decision until we've taken measurements and know what we're dealing with, feelings aren't facts, so until we know for sure we're guessing and hoping for the best, by the way I liked your video and the tip with the caliper and jo blocks, peace
Great and informative video as always. Would it be possible to use a touch probe to measure this feature more easily and accurately? It seems to me that probing could make measuring many of your more complicated part features easier. Thank you and stay safe.
Someone else mentioned this and it is possible. But my probe styli combination won't reach into the location. It would be very tight the way the probing cycles work. To tell the truth I hadn't thought of doing it that way. I may think about trying this if I can find a stylist that could be long enough and fit in there. the sphere on the end of the one I have on the probe is to large (6MM) and it's length is to short.
Thank you Peter for your comments on current events and the general public’s apparently docile abdication of their rights.
Большое спасибо.

Всё у Нас будет хорошо! Пандемия будет преодолена, мы все будем вместе жить на нашей планете Земля. Очень трудно объяснить людям что они все едины, все из крови и плоти, все похожи один на одного, не зависимо от цвета кожи, цвета и разреза глаз, от возраста и пола. Может быть это знание нам очень дорого достаётся, может быть. Но может нет другого способа объяснить это нам? Может после этого Мы будем более внимательны друг к другу и поймём, что у нас одна на всех планета Земля?
Храни Вас Бог. Будьте здоровы.
Thank you very much.
Your videos are very important and necessary for me, your time spent on its creation. Thank you so much for your time spent on me and people like me.
Everything will be fine with us! The pandemic will be overcome, we will all live together on our planet Earth. It is very difficult to explain to people that they are all one, all of blood and flesh, all look alike, regardless of skin color, color and section of the eyes, age or gender. Maybe this knowledge is very expensive for us, maybe. But maybe there is no other way to explain this to us? Maybe after that we will be more attentive to each other and understand that we have one planet Earth on all?
God bless you. Be healthy.
Great vid Peter. What about probing the broached feature?. Great words on freedoms being eroded.
That is a possibility but it’s to far back for my probe. And it would be very tight for a probing cycle. But it could be done with the proper stylist. Not a bad idea.
@@EdgePrecision understood. FYI I bought a broach for my mill/turn from Dumont. They provided a parametric macro for running it. Amazingly it was probably worth more than the broach. Maybe it'll help someone know this... thanks
Gauge blocks and spring calipers, they worked a hundred years ago, and still work today.
Awesome video as usual. That Go Gauge, did you make that, just based on drawing tolerances? Does it just split the tolerances, or MMC? Would be interesting to learn a little about making that gauge.
If you are referring to minim metal condition yes. That is a better description. I should have used that in this video. Yes to the drawing tolerances.
18:45 yeah I can see why you needed so many cutters with that many inserts laying around! Must be a huge production job with a abrasive material.

# AvE This precision machining and methodology is Jaw Dropping Awesome! On a lighter note, I wonder how this video commentary would have turned out if AvE had this size of tool using a broaching action, carrying a copious volume of pressurized moose milk ejecting from the inner diameter of the hole with every stroke (huge smile). AvE, you have corrupted our pure machinist thoughts!
Again, your precision machining and quality control is NASA quality work. Only Respect, and a little fun. Thank You.
In Dark Times, laughter and learning are powerful tools. Thank You!
I like your videos and thank you for the content you produce
I can't speak for everyone else but I'd much rather see content from you that you deeply understand (like the explanation of the G gode towards the end of the video) than content that you clearly have no understanding of (like the stuff at the beginning of the video). The former is literally why I subscribe to your channel. I feel like every time you set out to explain exactly what you're doing you apologize for doing so. You are among the most competent CNC machinists making videos. There's nothing to apologize for... well except that glare and washout on the yellow notepad, that didn't work out so great.

Great video Peter!
Hi Peter, an ardent follower of yours from India. Excellent video, as usual, I must concur.
And regarding CV thing, we feel we've been very lucky in India so far. No. of infections yet to reach 5 digits (thankfully, and hoping we don't reach there)... Fingers crossed for now.
Take care of your health !
Thanks. That sounds good! I hope it stays that way for you all.
Very well explained Peter. Interesting video again 👍
Thanks for all the extra work making the video. Is it possible to have different tool offsets for the same tool but in different sub programs used in the same program? I didn't notice you having to call the offset in the sub-program.
My screen shot didn't show the upper part of the main program where the offset for the tool first tool is called. There is actually two sections of the program that I ran in the video. The first tool does the back side and returns up to the tool change position.Than stops with a M01. Than it calls the second offset/tool (Same tool just rotated 180) and comes down to do the front side of the key. So this tool is running two offsets and tool setups (The orientation angle). The offset and tool information is called up than the tool is positioned to the start of where the sub program starts than retracts up and away after for each, Front and back. I should have made that more clear in the video. Hope that makes sense.
@@EdgePrecision It does, thanks Peter

They have militarized the police force so far off the deep end that many city police forces have armored vehicles now. If you are not a tRumpinski loyalist you are being run out of washington, and he has destroyed the constitution and constructed his own "acting" government structure. Its a similar repeating history to the german gov't of the 30's, like the CV19 is similar to the 1918 pandemic. Here is a spotlight on the playbook that just used the CV19 to seat another dictator.

Thank you for your intro. I agree with every word you say. We are crossing a line and can never go back. We will never know if it really served any purpose compared to the way we have always reacted in the past. So we will plan future policy on one data point which is essentially invalid as there is no real comparison or control. Pretty scary indeed!!
What I said I did with the hope it would make people think about just blindly following without giving a thought to what was sacrificed for what they have and enjoy. A week and a half ago to many it seemed a little far fetched. Now it seems a little closer to reality. And I’m sorry to say I think it will get worse yet. I thank all for their comments.

Peter, We just had 2 deaths in a senior home in their mid 90's, made it through the depression, battles in Europe and the Pacific, but they couldn't battle this virus, along with other seniors in this home, You're worried about your freedoms?

Your shop here in houston ? Never knew that great to know. Keep up the awesome videos

@@EdgePrecision awesome ! Same here our shop have nothing but mazak , but no integrex like yours , keep up the videos learning a lot from it.
Peter, I am a constitutionalist and libertarian, and am a "I'll never let you take my freedoms" kind of person. I also have degrees in chemistry/biochemistry, and almost another in microbiology. I have done a lot of work with virology, epidemiology, and microbiology. (Outside of "normal curriculum" school work.) I told my parents the first week of January that this virus will bring our country to its knees. I know far too much about viral pathology to be coaxed by fear mongering or politics, but this needs to be taken seriously. It's not the virus you have to worry about, as the death rate from the virus is very low. (The rate it is so high is because people that would have otherwise survived the virus, are dying because of a lack in available healthcare. Hospitals don't have the staff, supplies, equipment to deal with all these people.) Last time I was in the hospital, years ago, in a large hospital, in a large metropolitan area, I was in a hospital bed in the hallway the whole time. The hospital was so over crowded that all 75 rooms in the wrong were full with 2 people to a room, and flanking the two sides of the ball way were beds end to end with another 36 people. They were crowded them and they're even more crowded now. And people forget that this virus is IN ADDITION TO influenza and every other reason people are normally hospitalized. People that would sit in the hospital for 5 days and get better, are dying because of it. Also, there have been lots of confirmed stories of people being pronounced dead due to COVID-19 from infection by SARS-CoV-2, who DID NOT DIE FROM COVID-19. Some were never tested, some had been tested but had not received results back (but were still listed as dying from COVID-19 before knowing the results), some died of other reasons, and some are outright lies, like the infant that died in Connecticut. (The governor said that the infant was "the first infant death in Connecticut _related to_ COVID." It was not COVID-19, and the governor knew that. It does of SIDS, but had the virus in its system and was ASYMPTOMATIC. He knowingly LIED. There are hundreds of cases of someone dying, and the CoD lists "complications due to COVOD-19," but have absolutely nothing to do with COVID. The whole problem is those people in Wal-Marts and other stores, acting like nothing is going on. That is the whole thing that is going to cause us to lose our freedoms; people not taking it seriously for whatever reason. SARS-CoV-2 is highly virulent (much more so than _Influenzavirus),_ and it's going to spread like wildfire. The problem is that people are often ignorant to how viruses work and the epidemiology of the diseases they cause. Even idiot physicians are still prescribing antibiotics when someone comes in and has the flu, or even worse, prescribing an antiviral to someone who is young/healthy. So, please take it seriously, and it's only going to get worse. Also, due to cities/states/countries/whole continents are vastly under reporting the number infected. Some are doing it deliberately, or because they don't have testing access, or because they don't have enough test kits and lands to perform the tests, and some just because they lack healthcare and medical statistics altogether. (Like Africa. People were saying, "WOW, we're seeing almost no cases out of Africa." Duh, do you think a continent where 90% of the population doesn't have access to healthcare, is being tested? And do you think there's someone to keep track of those numbers even if they were treated? Ummm, no.)
I hope you don’t think I not taking this seriously. After all I’m in the higher risk age group. I think right now the best thing people can do now is take care of themselves. Do the things to keep their immunity response high. Eat right get plenty of sleep exercise if possible. Things like smoking drinking and other unhealthy things are you enemy right now. We’re probably all going to experience this virus in some way we should give ourselves the best chance. I don’t think the hospital is going to be a option. In fact it may be a good place to get it. I feel for the doctors and nurses. There putting themselves in real danger for their lives.
@@EdgePrecision Oh, I know you're not, and you didn't convey that. You have the same fears about losing freedoms that I do. I just was more putting that out there for everyone. You're the man, Peter.
@@EdgePrecision The number one thing anyone can do is... isolate. Don't breathe the same air as anyone unless you have to, wear a mask if you do, don't go near other people for at least a couple of months. Rest and healthy habits are great, but this virus has killed healthy 25 year olds, it's just less likely to do that than kill old folks. The only safety is in isolation.
great as always.
didn´t think about using the lathe as a shaper mashine, but now that i think about it it isn´t too big of a load on the axis.
Drilling puts much greater load on the Z axis than this.
Slow rising flood is still a flood..
Completely agree with you regarding the rights and freedom aspect of this.
Hi Peter! Could you please explain why you choose aluminium for the setup part, over e.g., cheaper steel? And secondly, how are you dealing with the differences in cutting forces and deflection between aluminium and the final material? Thanks, Hansi
Can't speak for him, but in the shop I work in we typically use aluminum because we have a lot of it and it won't damage or really wear tools cutting it at the speeds and feeds were using for whatever we're practicing for. That said we only practice when were making complicated parts from expensive material, so the cost of the aluminum is negligible.
I will add that the price of aluminum and steel doesn't turn out to be that much different. You buy material by the weight in these larger pieces. Now steel weighs almost three times what aluminum weighs .2833 pounds per cubic inch aluminum weighs around .1 pound per cubic inch. so the aluminum could be almost three time more expensive by weight and not cost any more. And also all the reasons Bill Mielke says.
@@EdgePrecision and Bill Mielke: Thanks for your replies and the explanation!
Just checked at a local metal supply, and indeed, _by_volume_ aluminium is only slightly more expensive for small quantities and less than 2x the price than the cheapest steel. On the other hand, stainless and tool steel are 2x-5x as expensive as aluminium. :-O Interestingly, PE and POM are the same price as cheap steel (again, by volume).
Nice greetings and best wishes from the locked down Austria, even having to wear masks in supermarkets since today.
Bye, Hansi
I'm old school and work only with hand operated equipment. I know nothing about g-code, but the way you explained it made perfect sense. Once set up how many units were in the order and is it an order that gets repeated?
This particular part? There are sixteen of them. But each part takes around three weeks to machine complete. So that in itself is around eleven months of work. On this machine.
@@EdgePrecision Holy shit, that is one full time job. Thanks for filming. I like your easy going style.
I've enjoyed your videos for a couple years now and i've always found them to be helpful and insightful. I've been running a hurco vmx42 for the last 8 months straight out of school and we have just received a mazak vtc-300c that i have been volunteered to run. Are there any resources that you know of that would be helpful in learning the control and getting this machine making chips? Happy birthday and i wish you many more.
With regards to the parts your machining in the horizontal. How many parts do you get per insert change/rotation per cutter? Seems like a lot of the same cutters in that tool changer.
Hi peter, in case of single part, isnt it much easier to put it on a sinker edm instead of broaching and manufacturing a custom tool?
There are sixteen parts. Any time you send a part to a outside process there is a chance of misalignment or worse. And besides I would rather get paid for it than the EDM shop.
@@EdgePrecision How does the "or worse" part work with an outside shop? Is there some sort of "Insurance" in the contract If they muck up (what looks to be) a five figure part?

I am choosing to EXERCISE my freedom to keep my distance from others and limit contact as much as possible, because I care about the lives of others.
If being asked to change your behavior and make a sacrifice in order to save your neighbor's lives and reduce suffering feels like a loss of freedom, maybe it's time to take a good look at how you choose to use the freedom that was secured for you by people dying and suffering and sacrificing so that we could live safe and comfortable lives.
I am over in the Bay Area, the first mandatory shelter in place area in the US, and very few people are complaining about it, and most are glad that they are safe from the sick people coughing down their neck.
In many places the people are demanding such restrictions. Oregon and Washington for instance, the governors were not wanting to order shelter in place, but everyone was watching California, and seeing how well it worked, and public fury finally got loud enough that Oregon and Washington made the order, and almost everyone is happy to follow the distancing rules, some because they are afraid of getting it, but there is a powerful grass roots uprising of people doing it to protect others, and lots of activity on social media supporting each other and encouraging everyone to stay home to save the lives of others, and it's working.
And sadly, like Italy, too many people and places are not doing it or taking it seriously until lots of cases in their area, and it's too late already.
The Bay Area got it pretty early, and it's working.
California followed suit soon after the Bay Area started spiking, and so the rest of the state started distancing BEFORE the case count spiked, and most of it is staying very low as a result.
If you aren't surrounded by sick people, it may not make as much sense, and by the time you are, well, ask Italy, or the British PM how well hoping it would go away worked for them.
And I know you were just wanting us to think about it, and I appreciate that you have been doing your part, and since you don't really have much contact with people I don't see continuing to work to really be much of a risk, but I am just sharing my thoughts on the freedom side of things, as someone who likes freedom lol
Esprit can do a manual tool path on geometry which simulate ok but this only works if your post processor supports it. Its a bear to loop so I sometimes use it to generate my first moves of gcode with safe start and end blocks for hand editing. You might be able to copy translate the path once it's on screen. Custom cycle will drop handwritten code in as well on the last page but again the post needs to use it. I've used a combination of the two to get around not having the probing package when I need it in a hurry. I'm using Esprit 2020 and factory posts right now.
What about in Esprit TNG are you using that?
Thx Peter nice vid! FWIW I don't mind a little thoughtful societal discourse even realizing some of the comments it will generate. I also see the trolls made it here. Anyway, so on the part you are feeding it "radially" as it is broaching but on the tool you are using Cartesian coordinates? I guess that makes sense why you can get the bore next to the key smooth, as I think about it.
I understand your programming and interesting broaching.
Great vid. I need to get more comfortable with G91
just don't forget to change it back! haha
Thanks Peter for your very informative and educating videos. The pencil drawing on yellow paper was too difficult to see and understand hope to see a computer simulating one day. The offset compensation could that wave been easier if you have grind the two inserts, so the where aligned properly. Ofcause the insert coating will be removed, but you are running the inserts very gentle when broaching. I've another tip when you use the gundrill and you don't want to scratch the bore that already is machined, you had that situation in another video, you could try to spay the gundrill on the side with Teflon coating.
Keep safe and again thanks.
Can I ask you a question? What did you watch the video on a Phone, Pad, or Computer. I keep forgetting that people may be watching these videos on something other than a computer with a high resolution screen. When editing the video it was clear to me but if you could tell me it gives me more information on whet people actually see. Thanks.
@@EdgePrecision It was my Ipad normal size, but I'll give it a try on my laptop not much better 14" screen or maybe my eyes are not the best anymore turning 54 years soon.
@@SR-ml4dn Thanks!
Keep up the good work
Yeah I'm working 12hr days atm. 8 at work and 4 at home programming to prevent crossover between shifts. Hundreds of hours worth of work on the shelves, Guess were in the lucky 'essential' class.
I with you on that is it worth giving up right knowing thay will never give them back .
Thanks for showing us the macro programs.it helps a lot.
Not a macro program, just a simple sub-program.
19:21 So much carbide! I Can see a lot of it on the background table...
Do you send it out for recycling?
Eventually I will yes.
Thanks for explaining the code and your diagram helped.
nicely done.. going on the assumption your tool came out correctly could the initial work offset been off a little in the y+ giving you a little more material in the x on the far side... i probably would have screwed myself chasing that haha. Almost paid up on my gantry style lathe (5 years) and i have still not posted a program, all hand written, post for it is still out of my budget.
Great video as always. you sure do amazing work. I agree with your point about considering every action very vcarefully, before you take it. People that are panic'd often will do anything to avoid a perceived bad outcome. However, here are some numbers you might want to consider. Houston has about 2.313 Million people and 19300 hospital beds. About 20% of everyone who contracts the virus needs hospitalization. If everyone gets sick around the same time, you will need 462,000 hospital beds!
In Italy, the doctors are having to decide who gets to live or die because they don't have enough beds, ventilators, medicine, so they choose who gets treatment, based on who is most likely to survive. People that are most likely to need this help are 50+, like you and I. The point of staying home is to slow the number of people who get sick all at once, so that the 19300 beds you have will never be overfilled. Also, lets not forget that some of the hospital staff are going to get sick as well.
You are a clearly a really smart guy and make a lot of very valid points, but consider the numbers and check them. Don't trust me. Please stay safe and healthy.
Agreed, if you are on a ventilator or dead freedom is pretty much academic concept. I like you don't like the Gov't telling me what I can and cannot do. Like the ole Janis Joplin songs says, "Freedom is just another word for nothing left to loose" . Let's stay healthy for now.
Sorry for all the questions. You mentioned you got the tool in the start position with the CAM software before running the broaching sub-program. Do you need to allow for the tool offset when deciding where to start, what I mean is, is the start point on the generous side to ensure the 1/8 corner radius is completely machined away despite the tool offset being moved a few times?
The only thing good about the current situation is the lack of traffic on the roads. Takes half as long to drive home.
Epic video as always Peter!
P.S. A sound of pleasure starts at 22.45
I think it's great you're willing to think independently about the tradeoffs, and are courageous enough to share your thoughts. That's freedom that can't be taken away.
To me, the thing that's unique about a situation like this is that the only solution is (almost) 100% community action. That's a hard thing to reconcile with individual liberties. We've been in other situations where we were willing to sacrifice a percentage of the population to maintain liberty, and did. But in those situations we chose who to sacrifice, a virus won't spare the politicians' sons.
So just I am getting this right the g91 is incremental just for that line the rest without the g91 are Normal?
When G91 is commanded it a modal command. A modal command stays in effect until it is changed or reset for all following lines in the program. So in this case the whole sub program is in incremental mode. It doesn’t have to be on every line.

I don't think the "Let it burn" method of dealing with a pandemic is a wise one. There are two problems #1 people can have it for ~10 days prior to showing symptoms (so effectively everyone should assume they have it and act appropriately) #2 there are people that are asymptomatic in that they can get it and have it and never show symptoms (if we look at the first 10 days they have it prior to showing symptoms and the next 14 days they have but don't feel sick that's 24 days they could be spreading) I see Texas working it's way up the chart, currently at 9,247 cases so far. What is the magic number to become SIP concerned? People shouldn't need their gov to tell them what to do. There have been studies that strongly suggest that going about business as usual tends to have a much higher economic cost than long term SIP.
Today is 11,259 cases for Texas on 09/Apr, that's a 2,000 case jump in 1 day.
12,125 cases in Texas on 10/Apr ~900 more cases.
16,638 cases for Texas on 18-Apr-2020. That's about 5,500 cases in nine days; six-hundred-plus additional cases a day. You're correct: business as usual is not the wise choice. It could totally collapse the economy.
You are correct Peter. Remember who it is with the motto "never let a crisis go to waste".
Excellent video as always, a perfect length. When the program exits the sub-program does it revert back to absolute positioning if it's in that mode, automatically?
Yes after the spring passes. If you look carefully at the screen shot on the main program you will see a G90 G0 Z1.0 right before the M9 command.
@@EdgePrecision Thanks Peter
There may be an upside to the current situation, less manufacturing going off shore.
Expect to pay more for things though.
Based 👊🏻
thoughtful precision!
Thanks for the post Peter
Great explanation Peter. I broach 304SS keyways on my lathe @150ipm .002 step. Am I running too slow? Anyways very good content as always. Thx
That spindle is huge!
Stay safe, wear a mask, start away from people and you'll be fine!
The problem with collective problems is that there's no individual solution -- we need to apply our ability to collaborate for the good of everyone.
Once it's over, we'll all be back outside.
Also: shaping with a form tool on a lathe? Sweet!
When you quote a job do you do it by hours it will take to complete and multiply that an hourly rate? Or do you just name a price?
