Anyone have a link to the formula for surface finish vs. IPT
vs. insert nose radius? It's also in Machinery's Handbook someplace
IIRC.


I have most of that info in the form Kennametal literature--rarely needed
here though.

A fairly simple explanation ( though not entirely complete--DOC and nose
radius comes into the picture too ) is that your IPT times your number of
teeth cannot be greater than the width of the "flat" on your "wiper tooth".
