Climb Milling vs. Conventional Milling

An explanation and demonstration of climb milling and conventional milling. Positive and negative points of each technique will be covered as well as examples of what can go wrong.

Hands-down one of the most informative pieces on climb- vs conventional milling. I accidentally clicked on this right before I was supposed to leave for a meeting, but was so impressed with it's depth of information, that being late was completely worth it. What a really, *really* great video and demonstration. To the point, clear, with immediate feedback, and you covered all the directions, angles and styles.

I wish all such videos I've found online were this informative, and in such an impressively short time too. (I've learned less in hour-long videos.)

Thanks for helping make me a better machinist.

I’ve been a Toolmaker for 22 years and today my son sent me a picture of his mill setup at his high school. I asked if they’re teaching them the basics like climb and conventional and he said no. I’m not a good person to explain with words so figured I’d do a quick search and your video came up. I’ll definitely watch it again with him as your explanation is far better than mine and the visual examples are excellent. Nice machine shop too. I’ve always wanted to have one but it’s hard to justify the cost when my employer allows us to use the shop for our own stuff on our own time. Thx again

This is a dude that is speaking from a lot of practical experience. No fluff here. This is priceless info for people interested in this stuff.

also your skills at doing cautious perfect small crashes and grabs WAS THE BEST IVE EVER SEEN--youve got in the hours milling thats for sure.

Sort of knew, but the standing stock jump brought it home; The stock vise grip against the jaws was a GREAT tip. This will live in my memory as I grow as a machinist. Thank you, great explanation.

Great information. As a newbie, I just bought a used combo mill-lathe and had a small project out of aluminum that, although I was aware of most potential pitfalls, my lack of tooling resulted in virtually ALL the problems you highlighted. It was quite shocking to see how much force can get transmitted into the carriage!
The real life demonstrations and countermeasures are really, really helpful!

This is THE best explanation of Climb vs conventional milling I have ever seen, and I have seen a few. I always new it was all about chip thickness but I never really visualised it as well as this.

[jonruffolo]

This finally makes sense. Professors never seemed to be able to properly explain it and I don't know why. Thank you!

[jimmilne]

Learned a lot, and your demonstrations (rather than just verbal explanations) make both the procedure and the results - desirable and undesirable - very clear. Super helpful. Thanks again.

I am not a machinist but I still need to make parts for my equipment and you just cleared up years of frustrating screw up and have saved me a lot of money. I have broken enough cutters and mills to supply a small country because I was doing every operation backwards. Thank you for sharing your knowledge, and my boys say I can't change how I do things.

[stanfischer]

Very good demo! An old timer once used the terms "push mill" (conventional) and "pull mill" (climb). I'll watch more of your channel.

[minimotorman]

Thank you for your video, just 18 minutes and now I "get" it. I went to school for a year, bought the textbooks, listened to the lecturer...but it never really sank in. Watching you explain things in action though, now it makes sense!

Again thank you, you earned a new subscriber.

[tomherd]

Besides the difference in milling, your placement of how to secure the part in the first place was thought provoking! Thanks, Tom

[wiredodger]

Nice job Tom.

I think of it as scooping, and clawing, climb milling. What I didn't know was the physics of how and why one worked better than the other depending on the finish you were working toward.

That lesson was presented really well.

Thanks Tom.

[IHFarmer]

One of the best videos on this subject with and example of what can and will happen. Just got a milling machine and was doing a decent climb cut of steel and it did what your example did but in my case it broke the end mill.
Thanks

[nitehawk]

Thank you Tom, I have read about climb milling but could not understand how it worked until I viewed your demonstration.

[egx]

Thanks Tom. This is so often over looked, misunderstood or disregarded. This video makes it pretty clear. Great demo.

I had an old school boilermaker show me everything I know about steel and he didn't do so in purpose he actually wished I never learned. I couldn't ask questions really or use welder on lunch to practice etc. now I'm learning different operations of machines used primarily in machine shops and it's be weird. I'm so grateful because I wouldn't learn it any other way but I'm also confused because you're giving away your and your brother machinists secrets away. I know it feels good to give back but not your livelyhood. thanks for the information you're definitely one of the more watchable how to videos with the milling that I've seen so far.

[robertcopp]

I think this might be the best video on this subject on youtube.

[scottthornton]

That is the best description i have heard explaining conventional vs climb milling. I had never thought of the chip formation. Great video. Thank you for taking the time to make, edit and post this.
