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

Vc = 65 m/min (from Table 10)

We know Vc = π DN /1000 m/min

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

 (b) For cemented carbide cutter

D = 150 mm

Vc = 140 (from Table 6.10)

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