toroidal milling cutter
Is necessary to calculate cutting speed on effective diameter.
We find out optimum feed from recommended chip thickness with
respect to machined material and depth of cut*.
*) Recommended cutting depths you find in product part of catalogue.

Surface quality
In following table No. 2 you find the maximum values of feed per
tooth
f
z
in relation with number of teeth of milling cutter and width
of wiper edge
a
 to achieve good roughness of machined surface
or keep the precondition
f
rev
<
 0,8.a
for different types of cutting
inserts.
You can use a special wiper insert to achieve a very good quality of
the machined surface. Fit one wiper insert into milling cutter instead
of one indexable cutting insert.
