摘要：This experimental aims at achieving the integrated approach to solve the optimization problem of EDMprocess. At any stage, the dominance factor of the input variables and output variables contained in the constraints andobjective functions can be computed. Electric discharge machining is categorized as a thermoelectric process in whichheat energy of spark is used to remove material from the work piece. The machining process involves controllederosion of electrically conducting material by the initiation of rapid and repetitive electrical spark discharges betweenthe tool and work piece separated by the dielectric medium. The present work is aimed at characterizing the electricdischarge machining of HCHCR steels on EDM. Since an electrode with micro features is employed to cut its mirrorimage in the work piece, it is necessary to investigate the machining efficiency of the electrodes used. Furthermore, toimprove the machining efficiency. The combination of gap voltage, Ampere setting were new line considered formaximum Material Removal Rate (MRR), Surface Roughness (SR), constrained circularity error and overcut. Theexperiments were carried out as per L9 orthogonal array with each experiment performed under different conditions ofsuch as Ampere rating, sparking voltage while machining
