The machinability studies of newer material have been emerging technology in the present decade because of the lacuna in area. Duplex stainless steel is widely used in chemical industries and structural components in coastal areas due to its higher corrosion resisting property. Assembling and processing of engineering components needs machining operation like turning, milling, drilling and grinding. From these drilling operation is most important manufacturing process for assembling the components. The main aim of this work is to investigate influence of process parameters on drilling operation in Duplex 2205. Here considered input parameters are spindle speed and feed rate, the responses considered are thrust force and torque. For investigating the drilling parameter influence Response Surface Methodology (RSM) and Taguchi analysis were used. The analysis of variance (ANOVA) table in RSM and rank table in Taguchi analysis are used to identify the parameter significance. Regression analysis is used to frame the empirical models. Further the developed empirical models are validated with experimental data proves its adequacy. Finally comparison made between RSM and Taguchi analysis discloses, RSM be the best among those analyses.
