Depth of Cut 0.2R
Ap

is the inclination angle of the machined surface.
If the depth of cut is shallow, the revolution and feed rate can be increased.
Water-soluble cutting fluid is recommended.
If the rigidity of the machine or the work materials installation is very low, or chattering and noise are generated, reduce the revolution and
feed rate proportionately.
