- Let's breakdown Chipload and Inch Per Tooth!
Part 2 of the Lakeshore Carbide Tooling Video Series!
Please do not laugh at my hand gestures ;) 5 Reasons to Use a Fixture Plate on Your CNC Machine: bit.ly/3sNA4uH
just finished watching this series on "speeds & feeds" and understand now the real reasons each of these items effects the cutting process. The combination of zig-zag and video presentation of chip result have turned on the light as nothing else I have seen before. Many thanks for a truly enlightening series.
An easier way to think of why it's bad to run slowly: Stop thinking about "time" and start thinking of "cuts": Just like with an axe, you can only cut so many times before it gets dull. Rubbing is where you're cutting a bunch of paper thin slices to split a log. This is why correct feeds and speeds are so important; You're moving your arm (the tool) laterally fast enough that you're biting off larger pieces of wood (material) to get what you want done before the axe (endmill) goes dull. If you bite off too much, the axe gets stuck and you have to hammer or pry it out. (the endmill breaks because a CNC machine can't stop rotation in time to prevent the shank or core from snapping off)
Thanks for the info! I always see videos of people barely scraping the material. I don't want to make their mistake.
You make it a playlist now!
Quick video and I felt I learned a lot. Thanks and keep up the great work.
Wow. What a dope way to do science experiments through practicality. Just make sure y'all protect your hears big time. Better to wear double protection.
Thanks for Your video. Now my chips look better and things get done more efficient..
You are the man.
Really informative and great video. But one thing I suggest is turning off auto focus on the camera when filming scenes like this.
where is the speeds and feeds worksheet that was supposed to be in description ?
Excellent explanation
Thanks for the info, answers a lot of the question that I got :c) got no CNC experiense exept for what I tau8ght myself in the basement with my small model cnc.
No sheet attached as you mentioned in the video
This is great stuff!
can you not add metric values as text as i dont use imperial, so it is hard to follow.
Que: what is the difference between chip load and depth of cut?
Awesome! Now what about DOC? Does that depend on how rigid your machine is?
You should look to the other camera when you are recording than when editing you cut to the camera.
Remember to do that like when changing subject or time to time.
And put the other camera closer.
I think it would be much better.
Ross Perot, is that you???
Link is broken. where can I find the excel file?
Wouldn't some diagrams help with the explanation? It's easier to see what's happening with the radius on the cutting edge, and why you need a deep cut with a cross sectional view.

from www.cnccookbook.com/CCCNCMillFeedsSpeedsBasics2.htm is the kind of thing i was thinking of, and really makes the point clear.
I have a couple of questions that I've not seen answers to yet from any of the channels I follow. What do you guys do with the waste or the "chips"? I've seen some lathes/cnc machines where they run different metals. Do you try and keep the materials separated? e.g. one bucket for aluminum, one for brass, one for steel, d etc. then just recycle them to the same people you buy the stock from? Also I've seen people who use large pieces of stock then machine them down to almost 1/4 the stock size, they like the extra "wiggle" room that the larger stock provides, is that normal or do you go with stock that is "close to" the dimensions of the final product. Is there any savings on cost when going with the larger stock vs the close to or is it just a matter of time, and if you want extra wiggle room? thanks and keep up with the great vids!
ah by wiggle room I mean if your end part is going to be 1in in diameter do you start with a part close to 1in say 1 1/4" or do you start with something like 3" in diameter just to be on the safe side of things give or take mistakes or other issues? I've seen some videos with people having been giving huge pieces of stock and they turn it into something tiny, and others who just go a bit above the end part dimensions and achieve greatness, like your silencer! ;)
You mention not wanting to make a tiny chip, or rub. In a video you just did recently on 3d machining, it looks like a good portion of the cutting was taking off very little material. Was that just deceptive because of the video, or was the tool actually spending a lot of time rubbing?
Is there any way to avoid that when doing that kind of profile cutting, to help increase tool life, or is it just the nature of the beast?
when are you going to learn metric lol it's not that evil
+daniel lyall I really struggle to focus when people talk to me in imperial.
+Scott Moyse that's ok I work in metric and use imperial tool all the time. what are the cost of those tool you sale
daniel lyall They vary quite a bit, so it depends what you need? We're selling Albrecht holders too, bloody amazing bits of kit.
You can't measure freedom in metric.
KimJong Un - Good news, you can! For the last 60 years or so, the inch has been defined as exactly 25.4 mm. So, inches, feet, yards, and miles, are all defined in metric.
If freedom includes pounds though then you're right. The pound is not defined in grams, so as far as I can tell it ends up being some irrational number.
why do you cut to a camera you dont look at, it looks stupid, sorry but it does, look at the camera, will be a better presentation, I work in broadcasting
