In the present work, Electrical discharge machining (EDM) was employed along with silicon abrasive powders mixed in dielectric fluid to machine AISI 52100 tool steel workpiece with copper electrode by adopting centered central composite (CCD) design of response surface methodology. To realize the process performance of material removal rate and surface roughness variables such as Pulse on time, duty cycle, peak current and the Silicon powder concentration with particle concentration and size of 2.5–2.8 g/L and 45–50μm, respectively, have been added into the kerosene dielectric liquid of a die-sinking electrical discharge machine. Analysis of variance (ANOVA) has been applied to study the influence of process parameters and their interactions. In addition a mathematical model has been formulated in order to estimate the process performance. Further, the parameters were optimized for maximizing MRR and minimizing SR using desirability function approach. The optimum settings of parameters are pulse on time 200μ𝑠, duty cycle 0.81, peak current 11A, concentration 4 g/l, for maximizing MRR and minimizing SR.The recommended optimal process conditions have been verified by conducting confirmation experiments. The obtained optimal settings are experimentally verified showing +5.2% and -4.65% as the relative errors for MRR and SR respectively.
