Abstract—Metal removal Techniques is a mature technology involving several disciplines of sciences. It is a continuously change in line with strategies material developments though out the manufacturing industry worldwide and also developing the metal cutting industry. This paper aims to make an experimental investigation on drilling behavior of Austenitic stainless Steel (AISI 316) and attempt made to optimize the process parameters using L9 Orthogonal array design of experiment of Taguchi methodology. The process parameters of spindle speed, feed rate and drill diameter are influenced by surface roughness and Metal removal rate during Drilling operations. The main objectives of this research paper to identify lowest thrust force and more metal removal rate (MRR) of drilling process through experimental analysis and theoretical calculations using Analysis of Variance (ANOVA). The result of the experiments indicates cutting speed play a dominating role in surface roughness and Metal removal rate in drilling process parameters.
