Optimizing feed and radial forces in CNC machining of P-20 tool steel through Taguchi's parameter design approach

Abstract

The objective of the paper is to obtain an optimal setting of CNC machining process parameters (cutting speed, feed rate, depth of cut, nose radius and cutting environment) resulting in optimal values of the feed and radial forces while machining P-20 tool steel with TiN coated tungsten carbide inserts. The effects of the selected process parameters on the chosen characteristics and the subsequent optimal settings of the parameters have been accomplished using Taguchi's parameter design approach. The analysis of the results shows that the optimal settings for low values of feed and radial forces are high cutting speed, low feed rate and depth of cut, small nose radius and cryogenic cutting environment.
