Optimization of EDM Process Parameters for Inconel-713

This experiment aims at achieving the integrated approach to solve the optimization problem of EDM process. At any stage the dominance factor of the input variables and output variables contained in the constraints and objective functions can be computed. The main objective of work is aimed at characterizing the electric discharge machining of INCONEL 713 steels on EDM. Since an electrode with micro features is employed to cut its mirror image in the work piece, it is necessary to investigate the machining efficiency of the electrodes used. Furthermore, to improve the machining efficiency, it is momentous to consider the effect of various influencing input and output parameters. In this project, a series of experiments has to be conducted with graphite electrode as a tool and INCONEL 713 steel as work piece to machine small depth on the work piece. The combination of gap voltage, Ampere setting is to be new line considered for maximum Material Removal Rate (MRR), Surface Roughness (SR), constrained circularity error and overcut. The main aim has to be identifying the electrode which could enhance the production of quality of impression and to have a significant contribution for modern industrial requirements. . The experiments has to be carried out as per L9 orthogonal array with each experiment performed under different conditions of such as Discharge current, Pulse on time and Pulse off time while machining.
