Admittedly a pretty general Q, but here's the rationale/context:
I have observed that it is possible to take too lite of a finish cut, in
both side milling and face milling, and in turning.
I've forgotten the exact scenario, but something like .002-005 was too lite,
and .015-.020 seemed to have been much better.
Whatever the exact differences in the numbers were, the appearance was
strikingly different, in manual lathe work as well.
Are there any guidelines/rules of thumb for finish cuts?
For example, in milling, on alum or unhardened 4140, using insert face mills
or 4 flute em sidemilling. Also in turning.
