The objective of proposed work is to optimize the process parameters like Cutting speed, Feed rate, point angle and Diameter of drill bit in drilling EN8 steel, based on key accuracy characteristics of drilled holes like Surface Roughness (Ra). The various steps involved to achieve the above objective are as follows. 1) Determine the technique used to solve the present problem, i.e., Robust Parameter Design. 2) The objective functions are formed based on Taguchi’s quadratic loss function for each performance characteristics, i.e., Surface finish. 3) After the objective functions are formed, control factors and their levels are identified. 4) The values for the control factors are selected based on operators (Drilling operators) experience, literature survey and some pre-experimental analysis. 5) The matrix experiments are conducted on EN8 steel material. 6) After the experiments are conducted, response variables are tabulated and analysis is conducted.
