Abstract—This paper is concerned with optimization of surface roughness when drilling of stainless steel SS304 with HSS drill. This study included drilling of SS304 with supply of Sic abrasive having grain size 650 and 1250 mesh size through abrasive slurry system. Abrasives not only used for cooling purpose but also increases the surface finish, MRR and reduce tool wear. Experiments were conducted on a universal milling machine. Response Surface Methodology (RSM) is applied for executing the planning of experiments. Analysis of variance is employed to find the significant control factors and percentage contributions of each control factor. The drilling parameters namely spindle speed, feed rate; slurry concentration and mesh size were optimized using multiple performance characteristics for surface roughness. The result shows that the feed rate, and spindle speed are the most significant factors which affect the surface roughness and performance in the drilling can be effectively improved by using this approach.
