2020-06-24
Spindle speed setting during processing:
N=1000×V/ (3.14×D)

N: Spindle speed (rpm/min)
V: cutting speed (m/min)
D: tool diameter (mm)
Processing feed rate setting: F=N×M×Fn
F: Feeding speed (mm/min)
M: number of cutting edges
Fn: cutting amount of tool (mm/rev)
Cutting amount setting per edge: Fn=Z×Fz
Z: number of blades of the tool

Fz: cutting amount of each edge of the tool (mm/rev)
