Assume a finishing stock of 0.1mm on all faces, and 0.2mm on all diameters. A roughing cut of 1.4mm is to be given on φ25. Roughing feed rate is 0.3 mm/rev and finishing feed is 0.15 mm/rev.
Roughing is done at 1500 rpm. Finishing is done at a constant surface speed of 125 mts/min with the maximum spindle speed limited to 1800 rpm.
In the above program, block number N45 corresponds to constant surface speed of 125 mts/min and block number N50 corresponds to limitation of maximum rpm 1800 rpm. Block number N95 – change over from constant surface speed to constant rpm mode.
