That is amazing, I would have never thought that you would see such a build up form as you go. To bad there isn't a video like this of a grinding or cutting wheel, that'd be pretty interesting as well.

Really interesting. It almost looks like pushing a snow shovel along (or cutting cheese)!

I wonder what it looks like with cutting fluid?

I'd love to see different angles and how they affect the cut.

Very cool. I would like to see regular speed from a couple feet back to get some idea of what I'm seeing in slow-mo.

Looked like cutting playdoh with a plastic knife. The way it flowed over the cutting surface is so cool.

When you get the feed and speed just right, the cutting action causes enough heat to soften the steel just ahead of the tool and the surface finish is shiny and uniform. With hot rolled steel this is at about 280 to 350 surface feet per minute.

Exactly. Those would be interesting as well.
Very interesting. I like seeing fast moving objects slowed waaaayyyy down, the close up makes even better.
The music also gives it a whole new perspective.

As the build up starts to get to the point of overcoming the want to stay vs. the need to move on some makes it under the cutting edge and impacts the finished product. I am sure people way smarter than me look at that and say hey how can all that build up be removed from the cut rather than folding over...

A lot like snow plowing a large lot and every pass having dry fluffy snow drift over the trailing edge of the plow only to leave a mess to have to go back and redo.. add flaps and your more effecient? ok the build up here may be so minute it does not matter hit it with a little emery cloth and good to go but can a better mouse trap be had?

I call BS. The first one they're cutting rocky road fudge. On the second one, they're cutting regular chocolate fudge...


Mmmmm fudge.

That is extremely cool. My bother is a metalurgist and was excited to see it, too. It's really interesting how you can see the importance of good chip formation and what happens to the underlying surface when a good chip isn't made. You can also see how much the TiN coated tooling helps. It would be interesting to see the same with high speed steel vs carbide tools.
