There process parameters in machining are all those parameters that are inherent to any machining operation and should have a suitable finite value to smooth and efficient removal of materials. Such parameters directly affect machining performance. In machining, three process parameters are (i) cutting speed or cutting velocity, (ii) feed rate and (iii) depth of cut.
