Analysis of Forces & Surface Roughness on Hardened Steel With Uncoated Ceramic Insert Using Taguchi Technique

Abstract

The objective of this paper is to analyze the influence of various turning process parameters such as cutting speed, feed rate and depth of cut on the Feed force, Tangential force & Surface roughness while machining hardened EN-353 steel with uncoated ceramic insert. The effect of the selected process parameters on the Feed force (FX), Tangential force (FY) and Surface roughness (Ra) have been accomplished using Taguchi’s design of experiments approach. The results indicate that the selected process parameters significantly affect the mean & variance of Feed force, Tangential force and Surface roughness. The percent contributions of parameters in the ANOVA table for Feed force (FX) for the depth of cut (87.99%) has a major contribution than that of feed rate (2.82 %) and the cutting speed (4.45%). Tangential force (FY), the depth of cut (81.56%) has a major contribution than that of cutting speed (3.8%) and feed rate (9.87%). Similarly the Surface roughness (Ra), has depth of cut (59.59%) has a major contribution than that of cutting speed (23.67%) and feed rate (4.64%). In all these cases the interactions are not having any major contributions. Keywords—Cutting force, Feed force, Surface roughness, uncoated Ceramic tool and ANOVA.
