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
Vc = 140 (from Table 6.10)
N = Vc × 1000 / π D = 140 × 1000/ π × 150 = 297 rpm
