Abstract:-Electrical discharge machining (EDM) is one of the most important Non-conventional machining processes. Voltage (V), Spark on time (Ton), Discharge current (Ip) are important process parameters in this technique. The values of these parameters significantly affect such machining outputs as the material removal rate. In this dissertation work three-dimensional thermo-physical model for the electrical discharge machining was developed using ANSYS software and experiment have been conducted on die sinking EDM using AISI 304 as a workpiece to investigate the effect of most significant machining parameters. For that L9 orthogonal array was developed, and material removal rate (MRR) for AISI 304 was measured for every experimental run. For validation purpose, parametric analysis using ANSYS has been conducted to predict the MRR. To find out the regression equation and optimum process parameters mathematical modeling of MRR has been carried out using MINITAB software.
