Wire-cut Electrical Discharge Machining (WEDM) is extensively used in machining of conductive materials producing intricate shapes with high accuracy. This study exhibits that WEDM process parameters can be altered to achieve betterment of Material removal rate (MRR), Surface Roughness (SR). The objective of our project is to investigate and optimize the potential process parameters influencing the MRR, SR while machining of EN-31 using WEDM process. This work involves study of the relation between the various input process parameters like Wire Speed, Flushing Pressure and Gap Voltage. Based on the chosen input parameters and performance measures L-9 orthogonal array is selected to optimize the best suited values for machining.
