I've been struggling to get a good surface on the lathe and mill. Since the lathes a little bit easier to control, what are good rules of thumb for insert tooling on the lathe?
Will a sharper angle insert produce a better finish than a large radius?
Will faster speeds produce a better finish than slower?
What angles of the insert matter the most for surface finish?
For me, it seems I get the best surface finished taking somewhat deep cuts of .050 or more under a pretty high feed rate. I think it's a situation where I don't know what I don't know.
Mostly I'm running mild steel a36, 1018. I Have been able to get decent service finish in stainless and some kind of mystery tool steel.
