Experimental Investigation on Effect of Drilling Parameters Using Taguchi and RSM Concepts

Abstract

The present work illustrates the effect of drilling parameters on performance measures like material removal rate and surface roughness. Several experiments were performed on C45 steel with non-coated and coated HSS twisted drills. The optimization was done using Taguchi’s Signal-to-Noise ratios and Response Surface Methodologies. The Optimal Combination of Process Parameters for MRR is obtained at Tool type: HSS-Cobalt, Point Angle: 136 degrees, Speed: 400Rpm, Feed: 0.09mm/rev. The optimal combinations of process parameters for Surface Finish are found as: Tool Type: HSS-Cobalt, Point angle: 118degree, Speed: 750Rpm, Feed: 0.03mm/rev. The RSM and Pareto chart results found that the tool type and speed are the most influencing factors for the responses respectively.
