Drilling operation is widely used in the aerospace, aircraft and automotive industries, although modern metalcutting methods have improved in the manufacturing industries, but drilling still remains one of the most common machining. In this study, focuses on the optimization of drilling parameters using the Taguchi technique to obtain minimum surfaceroughness (Ra. A number of drilling experiments were conducted using the L9 orthogonal array on VMC machine. The experiments were performed on SG500/7 plate using different twist drills under dry cutting conditions. The measured resultswere collected and analyzed with the help of the commercial software package MINITAB16. Analysis of variance (ANOVA)was employed to determine the most significant control factors affecting the surface roughness. The spindle speed (850,1150, & 1440 rpm), feed rate (90,120 &135 mm/min) and tool material (HSS, Carbide and TiAlN Coated Carbide) wereselected as control factors. The main and interaction effect of the input variables on the predicted responses are investigated. It is predicted that Taguchi method is a good method for optimization of various machining parameters as it reducesnumber of experiments. The results indicate the optimum values of the input factors and the results are conformed by a confirmatory test.
