Optimization of Surface Roughness and Flank Wear in Turning SCM440 Alloy Steel Using Taguchi Method

Abstract:

The purpose of this research paper is focused on the analysis of optimum cutting conditions to get minimum surface roughness and minimal flank wear in turning SCM 440 alloy steel by Taguchi method. L₉ orthogonal array is designed to conduct the experiments. Experiments are conducted on supercut 5XL Lathe using coated carbide tool. The process parameters are cutting speed, feed and depth of cut. Surface Roughness and Flank wear are selected as the responses. Surface Roughness is measured using Mitutoyo Surface roughness tester and Flank wear is predicted using SEM images after the experiments. The results are analyzed using analysis of variance (ANOVA) method. The regression equations for the responses are determined and the probability plots are plotted and found satisfactory. The R-squared values are also calculated using analysis of variances and it is found that these values are close to the proximity level and satisfactory. Taguchi method is used to analyze the dominating parameters in minimization of surface roughness and minimization of flank wear.,
