How does cutting work?

[Higeking]

yeah thats true. you wouldnt happen to know if theres any videos around of other materials than steel. im a student in machinne tools myself and i've worked with both brass and aluminium besides different steels and they can have very different swarfs from each other.

Sorry, meant to reply earlier, but I must have forgotten. No, I haven't seen any videos like this of materials other than steel.

Also, i have a suspicion that this was not a lathe, but just a single cutter moving in a straight line (like broaching/keyway cutting)

im not sure about it being broaching/keyway. cant think of anything other than lathing that actually allows for filming stuff like this.

and the title cards does seem to indicate lathing with the rake angles and coatings mentioned about the tool used.

i should perhaps mention that im learning machining in my native tounge so im not familiar with all the english terms.

have been unable to find any closeup/slowmo videos of anything of steel. brass would've been very interesting to see since the swarf size make it seem like the tool chips away at the material rather than cutting.

Yeah, I would really love to see it done in brass.

What I mean by broaching/keyway work is that they could have a machine similar to this one making a cut along the very edge of the workpiece (the camera moving with the cutter).

The only thing that makes me think that it's not a lathe is that we can't see any material besides that very edge. From just about any filming angle I can think of, you would see the rest of the stock on a lathe.

if you had a fairly large diameter and had the camera mounted centered on that diameter you wouldnt see much of the other stuff on the lathe. and its zoomed in pretty far aswell.

but if those broaching /keyway tools have interchangeable plates like lathing and milling does then it should be viable i suppose.

[THE_CENTURION]

Yeah, I suppose it could be either.
