I have been putting forth more effort into becoming a better CNC machinist after following you and watching your videos. You lift me up to peruse this career path Titan. I appreciate you for that. Thank you so much. You are leading me to success in this industry!! Iv never been more excited in my life!
Mr. TITAN, I'm from Nicaragua and I love CNC machines, I see all kind of machines videos since CZcams start to publish the very first videos of CNC machinery. But here in my country there is any school that teach students as CNC machinist... so my only way that I have to learn is through videos. And I want to thanks for your videos, I learn a lot with all you say in your videos and you are my motivation to keep learning and I have a very true vision and want to fight for it. Very thanks because you change my life since I start watching your videos because now I have a goal. God bless you Mr. TITAN
Some conversation about how chip-thinning makes those high feed-rates possible might be helpful. Also, some explanation of cubic-inches-per-minute of material removal. You do absolutely OUTSTANDING videos! You're enthusiasm for the trade is inspiring! Keep it up!
You sir are going to be a better source of knowledge than my employer. A year and a half ago I was hired here with NO machining knowledge. I was told I would be trained. I got a minimal amount of training and basically became a button pusher. I work the night shift with o e other guy who has no experience so I am all we have. I feel like I can be worth so much more to this company if I could learn more. Many times I can fix a problem but I dont know much about what I did. I appreciate your videos because they help me learn where my employer has failed. Thank you.
The people I work with are very slow to adapt to change. After watching your videos, I used fusion 360 to do some mass material removal in 304 SS and blew everyone's mind with how fast I was was going and how good it sounded.
Thank you Titan for everything you do. I’ve been running a Mazak QTN 250 lathe for a few years now. Trying to push myself and cut faster and effectively and it’s working out great! I still try and watch and learn about pushing a milling machine so when I transition back in the future I’m ready to push the limits. I’m looked at in my shop as young and dumb, but when they hear my machine throwing chips everywhere and getting after it, that’s my proof in the pudding. BOOM!!!
Hey Titan! I tried your recipe for 4140 with slight modification for a 4 flute endmill. And boy was I surprised! I mean it was just hard to believe and the tool life increased too! Thanks.
I am a newbie to machining. I got a job running right now that's taking forever, we get two parts off in a day's time. I just came across your channel and bragged about it to my boss, he finally gave me the go ahead to try some "new" tools for roughing 316 SS and I shaved almost an hour off our roughing with just one end mill. That tool is awesome! Went from running 9ipm, .0014"/tooth with a 4 flute 192 SFM, to 156+ ipm, .0064"+/tooth and 450ish SFM and still running a 8% stepover (that stayed constant). I was told it can't be done, but I think I just proved them wrong. I am running it on a 20+ year old haas vf2, the load on the tool is 30% and but I was told not to push it anymore because the machine can't handle it.
That’s Awesome! See that’s the name of the game. Time is money... keep doing that and your boss will make more and more money... and you Aaron will deserve higher pay.
I know that you machine alot of hard metals, when possible we waterjet cut the materials to near net shape so we use less roughers; it seems to be faster than machining especially when there's lots of material to remove. I know that you use kennemetal tools, but we have had luck with Guring drills holding up well in hard metals and Krycera drills working well in aluminum.
It would be lovely if you make a series on the process of selection of machine tools for various job descriptions, explaining the technical parameters of CNC machines and how you decide which machine to buy for what work. Thank you :)
So is the cost of tooling . My business in Australia, I charge AU $100/hr . It would be pointless to have a tool strategy that the tooling costs more per hour than the hourly you are making (tool that costs in excess of $300 & only lasts 90 minutes). My cnc mill 8000rpm spindle 2000mm travel in X , BT50 spindle. My roughing is done with a Seco R217.291-3240.3-06.4.075A cutter RPKT1204MOT-6-M15, MP2500 inserts. 2400RPM 3600mm/min 3.3 mm depth of cut 30mm stepover. They are a button insert with a location pin , so you can rotate 6 times. Tooling cost per part is low & material removal is faster than any other cutter I have tried. I am considering going to similar cutter but 63mm diameter & 7 inserts . In my cam simulation, this shows even more time savings.
I’ve been making chips for over 20 years , most of these lessons are great and you’re also impressive I’m sure the Zombie mill stared ultra aggressive machining. Worry not of a sub count, you know how to teach
SWEET SPOT is a term related to sfpm and relationship of feeds as long as this relationship is maintained you can go faster or slower depending on material
Thanks for all the videos Titan. Would you be able to address high speed roughing and then finishing of thin walled parts? We do a lot of that and it seems difficult to keep the parts from flexing/bending, solely from just the material being removed (even if cut slowly-mainly aluminum). Thanks for your contribution to the industry and your inspiration!
@Paul Hill "Ditto" on finishing strategies + stress relation of materials (beyond spring pass etc.) or how some materials may take much longer to move.
The only way to do thin walled parts is, dependant on machine, to first rough one side of the wall, then either plug support it or then do small steps of the other side of the material where it will subsequently keep supporting itself the deeper you go on the cutting level. When doing thin walls you need to completely change your order of operations and think how can i support the wall before the very last minute until it's standing on it's own. You are a machinist and you need to think outside the box.
@@thundercuck1779 understood. It seems more that when roughing and finishing one side of, say a housing, as soon as you remove material from the opposite uncut side, the first side dimensions will change due to the material relaxing or stress release. We are experimenting with plug and support methods now. Thanks for the input.
@@paulhill1683 It's very difficult to properly identify the problem without seeing the dimensions and shape of the thin wall itself and part for that matter. The biggest factor which creates residual stresses is heat affected areas with sudden cooling, any interrupted or sharp cutting paths will also create residual stresses. Are you machining from a cast or a bulk material, how are you clamping the stock material, are you accounting for flexure of the part when it's clamped pre and post roughing? Is the stock material made from stressed processes example, cold/hot rolled. What are the mechanical properties of the material. blablabla we could go on forever.
Yes! We actually do a ton of tall thin walled parts in Aerospace and have some great techniques... It’s an art but trust me, you can do it efficiently with the right EndMill and speeds and feeds. Will do a whole video on it... won’t be for a few weeks though as I want to also film samples not just talk about it
Love the HSM vids Titan! I've been adapting large machine strategies to a small benchtop cnc router and currently run over 250ipm on Adaptive cutting using Fusion 360. Love showing people possibilities! Machine on brother

Hey Titan, Can you talk about your higher feed rates in terms of chip load in future videos. You can't really jump from 100 to 800 IPM without increasing chip load, the number of flutes, or upping your RPMs. I'm just curious exactly what you're increasing and by how much. Also, when you do this are you keeping the same DOC and WOC? Your videos are great. Please keep it up. You're a positive influence on the world. We appreciate your efforts so much.
Titan thanks for everything you do. You talk about getting after it (roughing), the letting the material breathe, and coming back to "kiss the baby" (finishing). Can you elaborate on this? Like how fast to rough, what stock to leave for the finish pass? How to you let the part breathe? And at what feed rate do you finish? I know how to hit +/-.001" in aluminum no problem. But I've been a bit leery at quoting jobs that are in the tenths (+/-.0002"). Would love to see some videos on how to hit these tighter tolerances. Thanks again
Jobs like that are entirely dependant on a rock solid setup machine axis backlash (less than tolerance you have) and stoutness of your tooling set up. If anything sucks or if the endmill is too small chucked too long or trying to feed too fast it will deflect and you will fail. If all these are good it's still nail biting tolerances... hit the green button and nobody breathe.
@@TITANSofCNC Kiss the baby!!! Love that term, the face you make when you say it always makes me laugh. Good stuff. In the future video you mention, can you please throw in some pointers on how to then measure it? I have a machine probe on my new 2018 Haas VF-5SS but no CMM. Can it be done with mechanical measuring tools and probe? Would love to see your suggestions.
I have to say thank you for the continual inspiration as well as the tips! I'm stuck with older machines with limited (4k and 5k, haas tm-2 and gr-510) 40 taper spindles with slow (200ipm and 500ipm respectively) rapids. What kind of strategies can I implement to at least come close to being competitive? Im already on the fixturing path. We do a lot of sheet metal and copper tapping from 8-32 up to 5/8-18 in 316 and many countersinks in stainless that always slow me down. Thanks again for all the help, Mike.
Hey titan. When you get a chance. Can you go over finishing strategies for surfacing in aerospace alloys? I ask because I’m dealing with a new breed of parts. Engineers using “generative design” here at work. The geometry is basically free form. So tons and tons of multi-axis surfacing. Cheers 🍻
@Marcus Madrid "Ditto" also and same with "generative design" (some times I call it "degenerate-ive" design as some design folks don't see how to take the computed surfaces to something cleaner and more aesthetic and smidge easier to machine)… But never the less IS the future of faster, lighter, stronger, cheaper. +Marcus Madrid good call !
Great video. But you didn’t discuss the material that whips me. Lol. 17-4 in condition H-900. We had a job not too long ago with a very big, very deep pocket in it, and tried several different strategies. We settled on a Seco 638R, and were able to get some pretty good speed out of it, but tool life was just very unpredictable. It would cut great right up until it just sort of died. No real wear indicators. For what it’s worth, according to my CAM software, the pocket had about 5,400 linear feet of cut in it, using a 12% step over. Also had a nice holder in a new 40 taper machine and nice rigid vises. Cimcool at about 15% mix. What sort of parameters or advise do you have for hard 17-4?
Titan I am going to be testing some Kennametal drills I saw you promoting on CZcams, I am looking forward to it, it’s 304 stainless (a refrigerator hinge we stamp out) we drill and tap for 1/4-28 threads along with 5/8-24 hole, needless to say quality and quantity is the goal, the drill is KEM4150218 1 Drill, 5.5MM/.2165/3XD B041A05500CPG KC7325, I’ll let you know how it goes thanks!!
Depending on how many holes you have... the KenTIP FS was designed just for Stainless and is a Beast. Has to be the “FS” version though and it’s only for the larger size. Good for production of hundreds of holes or more.
Hi sir I recently watching your inspire video but my question is how i calculate speed and feeds in metric material HRC above 49 I searched Google I not happy and confused
Could you make a video using comparable endmills to the Kennametal ones you prefer? We use allot of Harvey, Helical, and Schultz. We cut everything from 6061 to 6AL-4V and some stainless and plastics.
Really enjoyed this video. I often find myself backing off the feed rates way below where I know I could be just because I'm missing the sweet spot. But like I tell people I work with they don't put flutes on endmills to make them look pretty they are there to be used. And it is definitely a lack of education in the industry perpetuating the myth of low DoC with high WoC. Like you said at beginning rigidity is key. Do you have any thoughts on maximizing feed rates in less than ideal setups? Also any thoughts on how to adjust SFM when using a long tool to reach out?
Hey Titan, have you looked into what levels of heat are generated by going faster, or slower, in those harder metals? Do you find that running faster adds or decreases the level of heat generated by the tool into the metal part? Is that also more, or less, beneficial for the tool, the part, and your overall cost of operation?
Well the quicker you can get in and get out... definitely helps. Tooling, Coolant, Chip evacuation etc all play a role also. Coolant Thru Tools... I actually run crazy fast in plastic for just that reason... Pound it and move on before heat rises.
How’s it going I used to run a hutch vmx 40i and was doing the high speed mill doing 600 ipm I have switched jobs now I run a haas vf 2 and doing the dynamic mill and I can’t get it to run 150 ipm the machine jerks around what am I doing wrong I think it’s because it’s not looking ahead in the program is there a code that I need to get the machine to run the speeds that I’m looking for thanks.
Hey Titan! I'm doing an vocational training as a Maschinist in Germany and we just had a course about high speed cutting (HSC). In our case it wasn't just on getting the feed high but also working with extreme Revolutions up to 60.000rpm while even using a 1 inch cutter. The point of this is that the cutting force is minimised by a lot and youre able to hit much higher tolerances an thin wall thicknesses. Of course you need a special milling machine with a special motor and tool holding system, capable of dealing with such high centrifugal forces. Do you have a similar system in your shop? And what do you think about that system? Love your videos!! Greetings from Germany!!!
@Caspar Bewerunge Would be good to have a video as to what one can get away with at different spindle speeds especially for surface finish , especially for a HAAS (level/ C frame mill). @Caspar B what are you using ? Sounds kinda DATRON-ish to me ?
@@extradimension7356 I don't know which exact Maschine it is is but it is a Maschine from the Deckel maho company which is now part of DMG Mori. It has two different spindle heads, one conventional one with normal gears and one where the motor is directly mounted on the spindle because because gears wouldn't be able to handle such high RPM
Well, all materials and tools have what we call a realm or sweet spot... At 60,000 RPM’s I would assume your talking aluminum or possibly steel. There are some tremendous machines and tools out there for big money that can run at crazy speeds but on machines that cost less than $200K, I would say you have to choose HP or RPM, meaning most high RPM machines lack true Rigidity and HP. Makes sense right, they give up one to excel in another. My new DMU50 is a little different as it’s got 20,000 RPM’s but also feeds at 1600 IPM. But it’s also over $200K. There is an art and a recipe to Machining fast... and please understand this Video was for Rigid Machines Cutting Hard Materials. Aluminum is a while different story... RPM’s lesson pressure but also cause vibration if you don’t have Rigidity. I rough incredibly fast and don’t worry so much about vibration as I am pushing with force... but then I slow down and kiss in my finish passes with the right recipe of feeds and speeds.
@@TITANSofCNC That's a good answer , seems the 15K 18K and 20 K RPM spindles are a good compromise if they have double windings, but to be honest the torque is really really small at higher RPMs anyway. Just wondering what the limits of smaller tools size are on like 18K spindle VS. getting one of those air driven speeders ? [Funny that 12K RPM stuck and suited most people (for a long time); now it's like 20K is the NEW 12k (lol).
No, It’s off the actual model which is an absolute and never changes. So if your material is .100 over the model, you move in .050 and if it’s .040 over... you move in .020 etc.
TITANS of CNC: Academy Thanks for the feedback. FYI your videos and tutorials are making a positive impact here in Australia, I own and operate a small CNC machine shop and teach night school CNC classes. I have just started getting a lot of NA18 (Monel 500) jobs and have found your videos very helpful. Also I encourage my students to view your content and have found that since they have been doing that their enthusiasm for the trade has increased 10 fold. Now I will be talking to Kennametal about some tooling solutions for our applications. Thanks again!
TITANS of CNC: Academy Hi Titan, how do hydroforce holders compare with shrink fit for rigidity? Would really appreciate your feedback on this one, especially with your experience running at the numbers you do.
I am new to cnc, and part of the Academy. But i have a question about these feeds and speeds... can i apply these numbers to all carbide tooling? or are these strictly for Kennametal tools. My shop does not use Kennametal, but I'd like to start applying these feeds into my roughing. Thanks for your videos and information Titan.
Titan I see you use most of kennametal tools only but why don't you use and show us sandvik tools they are also the king in machining world or show us the comparison because what you show us we do follow that
We currently machine everything at slower speeds using the tip of the tool. After watching your videos I wanted to try some of these high speed tool paths. I do not know what other machine tool companies offer but we own 1 year old mazak machines. They are not currently capable of running these high speed tool paths do to the options needed for this are locked in the control, we would need more memory and high speed smoothing( cost is about 8k$ per machine). Is this common?
@@TITANSofCNC good to know, we currently run fusion but because of the memory size we are limited to program sizes of around 9k lines without the memory option upgrade. Most everything we program is done conversationally from the control threw mazatrol.
Try to run with DNC(direct numerical control) from your computer. I use this method on my Haas in case a very long programs when control memory is to small to implement it.
Understood @@waynemartin3508 .Mazak want money for every basic function.My mate runs few Mazak machines with mazatrol only but he makes big quantity batch works generally . One program by hand and go.
Hey titan, how long does it take for the machine to reach 800 ipm? Cause i could barley reach 400 ipm on a part 8 inches long. & thats on on a haas using g187 p1
Agreed... you need good straight always and of course a good machine. Haas’s slow down in the corners etc. My new DMU50 gets set up on Monday and they are saying it goes 1646 IPM... Oh Man, can’t wait.
I am a long time machinist and I am using a six insert 2.5 inch iscar shell mill cutting some A36 12 x 24 inch parts four pieces at a time on a HAAS GR512 at 60 inches a minute and .0625 depth of cut with a 1.2 step over, how can I see if I can go faster or deeper?
I don't even use a chart anymore just listen to the harmonics and build up slowly pitch changes should quiet down if it's right. Then examine your inserts after a set has run. Somethings you don't want to mill at ludicrous speed even in roughing and even if the machine can handle it especially in aerospace. I've seen guys make endmills steam make the part in half the time and it comes out visually looking nice... Then it goes to the customer and fails gets rejected from x ray inspection micro stress fractures.
@@extradimension7356 Yeah 7075 t6 has a tendency probably due to the chemical bonds being a higher zinc content. T10 can also do it usually it's noticed after heat treatment due to striations and expansion cooling. Others include some newer shape memory alloys not available to the public.
TITANS of CNC: Academy This is great ! Can you guys do some videos on BEST surface finish (strategies) on different materials and harnesses. Or out it another way how to get best surface finishes and tolerances from a HAAS (like / type machine). In industry the "Mantra" is to have super rigid machine and if you don't your surface finishes will be lousy. Care to 'Myth-bust" that one ? ["How to kiss the Baby " ?]. (That might save some "Peeps" out there hundreds of thousands of dollars on up front costs when investing in suitable equipment.). Awesome to hear this level of practical "Artistry" and "Technique" from someone that is passionate about process, in general. [Keep it up/Awesome stuff !].

But I've been a bit leery at quoting jobs that are in the tenths (+/-.0002"). Would love to see some videos on how to hit these tighter tolerances. Thanks again
Will do in a future video...
Ha ha:-) Kiss the Baby!
So many viable to discuss...
Stay tuned
Jobs like that are entirely dependant on a rock solid setup machine axis backlash (less than tolerance you have) and stoutness of your tooling set up. If anything sucks or if the endmill is too small chucked too long or trying to feed too fast it will deflect and you will fail. If all these are good it's still nail biting tolerances... hit the green button and nobody breathe.
@@TITANSofCNC Kiss the baby!!! Love that term, the face you make when you say it always makes me laugh. Good stuff. In the future video you mention, can you please throw in some pointers on how to then measure it? I have a machine probe on my new 2018 Haas VF-5SS but no CMM. Can it be done with mechanical measuring tools and probe? Would love to see your suggestions.
Awesome video!
I have to say thank you for the continual inspiration as well as the tips! I'm stuck with older machines with limited (4k and 5k, haas tm-2 and gr-510) 40 taper spindles with slow (200ipm and 500ipm respectively) rapids. What kind of strategies can I implement to at least come close to being competitive? Im already on the fixturing path. We do a lot of sheet metal and copper tapping from 8-32 up to 5/8-18 in 316 and many countersinks in stainless that always slow me down.
Thanks again for all the help,
Mike.
Thanks for the video, great work,
Waiting for the 5 Axis video.
Good lessons thanks 🙏
Hey titan. When you get a chance. Can you go over finishing strategies for surfacing in aerospace alloys?
I ask because I’m dealing with a new breed of parts. Engineers using “generative design” here at work. The geometry is basically free form. So tons and tons of multi-axis surfacing.
Cheers 🍻
@Marcus Madrid "Ditto" also and same with "generative design" (some times I call it "degenerate-ive" design as some design folks don't see how to take the computed surfaces to something cleaner and more aesthetic and smidge easier to machine)… But never the less IS the future of faster, lighter, stronger, cheaper. +Marcus Madrid good call !
EXTRA DIMENSION m
I will go over all
@@TITANSofCNC That would be awesome! + Forward looking and super helpful.
Great video. But you didn’t discuss the material that whips me. Lol. 17-4 in condition H-900. We had a job not too long ago with a very big, very deep pocket in it, and tried several different strategies. We settled on a Seco 638R, and were able to get some pretty good speed out of it, but tool life was just very unpredictable. It would cut great right up until it just sort of died. No real wear indicators. For what it’s worth, according to my CAM software, the pocket had about 5,400 linear feet of cut in it, using a 12% step over. Also had a nice holder in a new 40 taper machine and nice rigid vises. Cimcool at about 15% mix. What sort of parameters or advise do you have for hard 17-4?
Titan I am going to be testing some Kennametal drills I saw you promoting on CZcams, I am looking forward to it, it’s 304 stainless (a refrigerator hinge we stamp out) we drill and tap for 1/4-28 threads along with 5/8-24 hole, needless to say quality and quantity is the goal, the drill is KEM4150218 1 Drill, 5.5MM/.2165/3XD
B041A05500CPG KC7325, I’ll let you know how it goes thanks!!
Depending on how many holes you have... the KenTIP FS was designed just for Stainless and is a Beast. Has to be the “FS” version though and it’s only for the larger size.
Good for production of hundreds of holes or more.
Hi sir I recently watching your inspire video but my question is how i calculate speed and feeds in metric material HRC above 49
I searched Google I not happy and confused
More great content! Thanks Ttan :-)
Thanks for the best lesson
Boom
Could you make a video using comparable endmills to the Kennametal ones you prefer? We use allot of Harvey, Helical, and Schultz. We cut everything from 6061 to 6AL-4V and some stainless and plastics.
Another killer vid Titan!!. Just as a gauge, what would expect longevity wise, from an endmill high speed machining 316L? Cheers man!
Really depends on Rigidity and Applicatiion but in the 2-7 hour range.
Thanks Titan. I've been using indexable due to a low speed machine but we've just fixed up a vmc we bought so now we can play! 😁 Thank you again!
Really enjoyed this video. I often find myself backing off the feed rates way below where I know I could be just because I'm missing the sweet spot. But like I tell people I work with they don't put flutes on endmills to make them look pretty they are there to be used. And it is definitely a lack of education in the industry perpetuating the myth of low DoC with high WoC. Like you said at beginning rigidity is key. Do you have any thoughts on maximizing feed rates in less than ideal setups? Also any thoughts on how to adjust SFM when using a long tool to reach out?
Do you send your shirts to Poland as well? And why are they twice as expensive than brand shirts in Poland?
Yes! Price isn’t that bad either... check out our New Store at academy.titansofcnc.com
Hey Titan, have you looked into what levels of heat are generated by going faster, or slower, in those harder metals? Do you find that running faster adds or decreases the level of heat generated by the tool into the metal part? Is that also more, or less, beneficial for the tool, the part, and your overall cost of operation?
Well the quicker you can get in and get out... definitely helps. Tooling, Coolant, Chip evacuation etc all play a role also. Coolant Thru Tools...
I actually run crazy fast in plastic for just that reason... Pound it and move on before heat rises.
Wow man really great video, thank you
How’s it going I used to run a hutch vmx 40i and was doing the high speed mill doing 600 ipm I have switched jobs now I run a haas vf 2 and doing the dynamic mill and I can’t get it to run 150 ipm the machine jerks around what am I doing wrong I think it’s because it’s not looking ahead in the program is there a code that I need to get the machine to run the speeds that I’m looking for thanks.
when is the aluminium video coming out?
Nice tip
Titan what's the best software your useing telling you all this info for material,cutter selection,speeds and feeds,etc.?
Hey Titan!
I'm doing an vocational training as a Maschinist in Germany and we just had a course about high speed cutting (HSC). In our case it wasn't just on getting the feed high but also working with extreme Revolutions up to 60.000rpm while even using a 1 inch cutter. The point of this is that the cutting force is minimised by a lot and youre able to hit much higher tolerances an thin wall thicknesses. Of course you need a special milling machine with a special motor and tool holding system, capable of dealing with such high centrifugal forces.
Do you have a similar system in your shop? And what do you think about that system?
Love your videos!!
Greetings from Germany!!!
@Caspar Bewerunge Would be good to have a video as to what one can get away with at different spindle speeds especially for surface finish , especially for a HAAS (level/ C frame mill). @Caspar B what are you using ? Sounds kinda DATRON-ish to me ?
@@extradimension7356
I don't know which exact Maschine it is is but it is a Maschine from the Deckel maho company which is now part of DMG Mori. It has two different spindle heads, one conventional one with normal gears and one where the motor is directly mounted on the spindle because because gears wouldn't be able to handle such high RPM
Well, all materials and tools have what we call a realm or sweet spot... At 60,000 RPM’s I would assume your talking aluminum or possibly steel.
There are some tremendous machines and tools out there for big money that can run at crazy speeds but on machines that cost less than $200K, I would say you have to choose HP or RPM, meaning most high RPM machines lack true Rigidity and HP. Makes sense right, they give up one to excel in another. My new DMU50 is a little different as it’s got 20,000 RPM’s but also feeds at 1600 IPM. But it’s also over $200K.
There is an art and a recipe to Machining fast... and please understand this Video was for Rigid Machines Cutting Hard Materials. Aluminum is a while different story... RPM’s lesson pressure but also cause vibration if you don’t have Rigidity. I rough incredibly fast and don’t worry so much about vibration as I am pushing with force... but then I slow down and kiss in my finish passes with the right recipe of feeds and speeds.
@@TITANSofCNC That's a good answer , seems the 15K 18K and 20 K RPM spindles are a good compromise if they have double windings, but to be honest the torque is really really small at higher RPMs anyway. Just wondering what the limits of smaller tools size are on like 18K spindle VS. getting one of those air driven speeders ? [Funny that 12K RPM stuck and suited most people (for a long time); now it's like 20K is the NEW 12k (lol).
When you use Model Box point then move the xyz triad to the top left, it is inside the stock. Won’t that be a problem when locating the work offsets?
No,
It’s off the actual model which is an absolute and never changes.
So if your material is .100 over the model, you move in .050 and if it’s .040 over... you move in .020 etc.
I don’t understand. Why not use the stock box point?
Are you using chip thinning for the low radial engagement?
How do you go on with older machines with limited programming memory
Hi Titan, can we run these feed and speed numbers with a belt driven spindle or are these numbers suited for direct gear drive spindles?
It doesn’t take a ton of HP because of the small Radial cut.. so just depends... if you struggle, just drop the Radial step in by 20 or 40%

Thanks for the feedback. FYI your videos and tutorials are making a positive impact here in Australia, I own and operate a small CNC machine shop and teach night school CNC classes. I have just started getting a lot of NA18 (Monel 500) jobs and have found your videos very helpful. Also I encourage my students to view your content and have found that since they have been doing that their enthusiasm for the trade has increased 10 fold.
Now I will be talking to Kennametal about some tooling solutions for our applications. Thanks again!
TITANS of CNC: Academy
Hi Titan, how do hydroforce holders compare with shrink fit for rigidity?
Would really appreciate your feedback on this one, especially with your experience running at the numbers you do.
does high efficiency milling is the same as the high speed milling ?
Hello sir how are you, you are doing good, I want to join you sir
What is the fastest Feed Rate have U ever Ran?
What would you recommend for aluminum? (Particularly 6061)
??? EndMill or Facemill
TITANS of CNC: Academy I mostly use end mills, but I guess face mills too
I am new to cnc, and part of the Academy. But i have a question about these feeds and speeds... can i apply these numbers to all carbide tooling? or are these strictly for Kennametal tools. My shop does not use Kennametal, but I'd like to start applying these feeds into my roughing. Thanks for your videos and information Titan.
I would adjust down for other tools and trust me it does matter... These are proven speeds for the HARVI 3 only.
@@TITANSofCNC Thanks for the imput and reply Titan
Titan I see you use most of kennametal tools only but why don't you use and show us sandvik tools they are also the king in machining world or show us the comparison because what you show us we do follow that
We currently machine everything at slower speeds using the tip of the tool. After watching your videos I wanted to try some of these high speed tool paths. I do not know what other machine tool companies offer but we own 1 year old mazak machines. They are not currently capable of running these high speed tool paths do to the options needed for this are locked in the control, we would need more memory and high speed smoothing( cost is about 8k$ per machine). Is this common?
Try Fusion 360, it’s Awesome, inexpensive and smoothing is built in.
@@TITANSofCNC good to know, we currently run fusion but because of the memory size we are limited to program sizes of around 9k lines without the memory option upgrade. Most everything we program is done conversationally from the control threw mazatrol.
Try to run with DNC(direct numerical control) from your computer. I use this method on my Haas in case a very long programs when control memory is to small to implement it.
@@orowski4414 wish I could but that is an upgrade from mazak as well, call it ethernet running.
Understood @@waynemartin3508 .Mazak want money for every basic function.My mate runs few Mazak machines
with mazatrol only but he makes big quantity batch works generally . One program by hand and go.
can you please give the metric speeds?
Coming soon
Hey titan, how long does it take for the machine to reach 800 ipm? Cause i could barley reach 400 ipm on a part 8 inches long. & thats on on a haas using g187 p1
Agreed... you need good straight always and of course a good machine. Haas’s slow down in the corners etc.
My new DMU50 gets set up on Monday and they are saying it goes 1646 IPM... Oh Man, can’t wait.
I am a long time machinist and I am using a six insert 2.5 inch iscar shell mill cutting some A36 12 x 24 inch parts four pieces at a time on a HAAS GR512 at 60 inches a minute and .0625 depth of cut with a 1.2 step over, how can I see if I can go faster or deeper?
I will do some similar cuts in upcoming videos and you can compare!
I don't even use a chart anymore just listen to the harmonics and build up slowly pitch changes should quiet down if it's right. Then examine your inserts after a set has run. Somethings you don't want to mill at ludicrous speed even in roughing and even if the machine can handle it especially in aerospace. I've seen guys make endmills steam make the part in half the time and it comes out visually looking nice... Then it goes to the customer and fails gets rejected from x ray inspection micro stress fractures.
@@fireteamomega2343 Oooh what alloys ? That's some kind of aluminum based alloy ?
Thanks Titan
@@extradimension7356
Yeah 7075 t6 has a tendency probably due to the chemical bonds being a higher zinc content. T10 can also do it usually it's noticed after heat treatment due to striations and expansion cooling. Others include some newer shape memory alloys not available to the public.
Is there a second op video for the titan 10m
No
We teach you the necessity tool paths in the Titan-9M and then ask you to figure it out. Everyone who finishes 9... finishes 10
Thank you

@@TITANSofCNC ... Sarcasm xD...... ?
What's an inch?
TITANS of CNC: Academy This is great ! Can you guys do some videos on BEST surface finish (strategies) on different materials and harnesses. Or out it another way how to get best surface finishes and tolerances from a HAAS (like / type machine). In industry the "Mantra" is to have super rigid machine and if you don't your surface finishes will be lousy. Care to 'Myth-bust" that one ? ["How to kiss the Baby " ?]. (That might save some "Peeps" out there hundreds of thousands of dollars on up front costs when investing in suitable equipment.). Awesome to hear this level of practical "Artistry" and "Technique" from someone that is passionate about process, in general. [Keep it up/Awesome stuff !].
Yes! Will do
@@TITANSofCNC Good bit of "Myth-busting" would be awesome from folks that can really do it / bring it ! [Thanks so much].
You guys hiring?
The chip loads you talk about make me ashamed...I think I'll drink a protein shake and go turn up some feed rates...
