An Experimental Investigation to Optimize the Process Parameters of Surface Finish in Turning AISI 202 Stainless Steel Using Taguchi Approach

This paper aims at optimization of process parameters of surface finish for turning AISI 202 austenitic stainless steel using Taguchi approach. Nine cylindrical bars of AISI 202 of diameter 20mm are turned to a length of 20 mm in each experiment for a constant spindle speed of 73.5 rpm on conventional lathe machine. Coolant concentration, Feed rate, Depth of cut and rake angle of tool are taken as the process parameters. A Taguchi orthogonal array is designed with three levels of machining parameters and analysis of S/N ratios, response table and regression equations were made with the help of Minitab 16 software.
