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.

Well, the experience you've gained from all those years is something money can't buy. And I'm sure there are a whole lot of people, like me, who really appreciate that you take the time to share it with us. If I could, I'd give you all those nickels myself, but I'm still saving up for my own tools. :-/

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.

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

Great video and a real help for those of us who are not quite sure what we are doing. Thanks.

This is great for a manual machine. You are spot on with all the issues and benefits. Additionally, on a CNC with ball screws and very little backlash, climb milling is best all around due to the better chip clearance and better surface finishes. As an added bonus, tool life also goes up with climb milling with light, fast passes (High Speed Machining or High Efficiency Machining) on a CNC.

@TomsTechniques

Thanks Tom. Tool life is definitely better when climb milling due to the lack of rubbing as the cutter enters the work. Tom

Excellent class, Tom.

I retired with 34 years machine shop experience, with at least half of the years being a Milling machine specialist- meaning my entire work day was using Milling machines. A couple of additions I'll make is that the conventional Milling pull on the cutter can actually undercut the metal being machined. If the operator checks a part thickness and notes there's for instance, .200 of material left to remove and in turn positions the table to remove .200, the resulting cut cut may actually take off more than .200. This is because the conventional cut will "pull" the cutter into the material being machined. This result is compounded when using a long narrow cutter that bends easily. The operator may have a layout line on the top of the part but after the conventional cut completes, the bottom of the machined part thickness may be undercut while the top layout line is still visible . This is because the cutter bends in at the bottom during conventional cuts. The opposite occurs with climb cutting - the bottom of the cutter is deflected off of the part - resulting in a tapered thickness with the bottom being thicker. If one made a climb cut pass to the layout line on top, the bottom of the part may be thicker. If the operator floats the cutter back across the part in a conventional direction, the bottom of the part may be undercut. This will all vary with the length and diameter of the cutter along with how much material is being removed in one cut. Aircraft machine shop.

Good points. End mill deflection is why I always square up parts by end milling rather than side milling. I retired recently as well after 45 years of making chips, and guess what? I'm still making chips. At least I'm doing for myself now instead of someone else.

this is a much more interesting point than what my teacher told me in school, all he said was climb milling wears out your cutting edge faster, conventional makes it last longer, so always conventional mill, but now I see I should do conventional for rough milling, and climb for the last fine cut, cheers!
