Abstract

The objective of this paper is to obtain optimal turning process parameters (cutting speed, feed rate and depth of cut) resulting in an optimal value of feed force, tangential force and surface roughness for machining EN-19 steel with an uncoated carbide tool insert. The effects of the process parameters on the feed force, tangential force and surface roughness have been arrived at using Taguchi’s design of experiments approach. The results indicate that the selected process parameters significantly affect the mean and variance of feed force, tangential force and surface roughness. The contributions of parameters from the ANOVA table for measured feed force, the depth of cut (95.18%) has a major contribution than that of cutting speed (2.29%) and feed rate (1.16%). Similarly for a measured tangential force (Fy) the depth of cut (87.4%) has a major contribution than that of feed rate (9.08%) and cutting speed (0.91%). In case of measured Thrust force (Fz), the depth of cut (74.87%) has a major contribution than that of cutting speed (4.7%) and the feed rate (3%). Similarly the surface roughness (Ra) measured on the workpiece, the depth of cut (59.03%) has a major contribution than that of cutting speed (23.97%) and feed rate (9.04%). In all of these cases the interaction effects are not having any major contributions. The predicted optimum feed force, tangential force and the surface roughness are 107.03 N, 144.45 N, and 0.915 µm respectively are very much near the experimentally obtained values.
