Formulas used

n = 1000 · Vc / (π · D)Spindle speed from cutting speed and tool diameter.

Vf = n · z · fzTable feed from speed, flute count and feed per tooth.

Q = ae · ap · Vf / 1000Material removal rate in cm³/min.

Pc = Q · kc / (60000 · η)Cutting power with specific cutting force kc and machine efficiency η = 0.8.
