Calculate the Spindle Speed in Milling Operation

Calculate the spindle speed (N) if a copper job is to be milled by

(a) stellite cutter

(b) cemented carbide cutter.

The diameter of the cutter being limited to 150 mm.

Solution

D = 150 mm

(a) For stellite cutter

V_c = 65 m/min (from Table 10)

We know V_c = π DN /1000 m/min

N = (V_c × 1000 )/ π D = 65 × 1000/ π × 150 = 138 rpm

(b) For cemented carbide cutter

D = 150 mm

V_c = 140 (from Table 6.10)

N = V_c × 1000 / π D = 140 × 1000/ π × 150 = 297 rpm
