For those that are interested in what's happening when you're turning metal:

Cutting steel magnified and slowed down. [VIDEO]

Just like cutting Jell-o!

That is awsome. I can see why swarf curls the way it does.

 

[MarkD]

That's pretty cool!

 

[Andrew_K99]

Very cool!

It was interesting to see a blob of the material was actually doing the cutting as it was being pushed by the edge.

I wonder how they took the video.

That was the first thing I saw also!
And then when the 'glob' go to big it just rolled under the tip of the cutter. Would have been nice to know what the material was being cut too....

... Would have been nice to know what the material was being cut too....

The lead-ins for each segment tell you what the material is except for the last (4th) segment.

Mild steel
ESR (420) no coating on the cutter
ESR (420) TiN coating on the cutter
Stainless (some other sort) TiN coating.

That blob is called the "built up edge" and when that breaks off you get bad surface finish. Coatings improve lubricity to help prevent the BUE. If there was any wonder about how work hardening can occur this sure shows it.

Very interesting video. It looked like it was cutting clay the way it piled up in front of the cutting tool and sometimes even ran unde the cutting tool.

Thanks for sharing.

Appears to be video off an Scanning Electron Microscope.

Pretty cool video.

Seems so. Just hook up your camcorder to the SEM in your garage, aim it at your lathe, and hit the record button. What could be easier? When you're done just refill with electrons. They're cheap. :biggrin:

Thats funny......:biggrin:

I still got plenty of them dang electrons, my brother gave me his extras.
Im thinking Im gonna cast them in PR....

 

[tbroye]

Very interesting. The metal almost looked fluid. Or like someone else said clay.

Best use Alumalite(sp), i hear some of them 'electrons' is damp. Could make a bunch of foam.:redface: DAMHIKT

That was very interesting.

 

[Haynie]

Cool. When I was a kid I had a tow bulldozer I would make roads with. It reminded me of that.

 

[toddlajoie]

I thought it was interesting when it seamed to be tearing the material quite a ways ahead of the cutter. Still seemed to be relatively a strait cut, but you could see it moving in or out from the intended cut area as the split reached the blade...

Cutting metal with a Mozart accompaniment. Now that is different. Amazing how fluid the steel is.
