Evaluating the optimum level of Electrical Discharge Machining parameters regarding decreasing electrode wear ratio by using response surface method
Abstract The effect of Electrical Discharge Machining (EDM) parameters (i.e., Voltage, Peak current, Pulse on time and Pulse off time) was investigated in order to minimize the electrode wear ratio. Effects of selected parameters on process variable, electrode wear ratio was investigated by developing the mathematical model using response surface method (RSM). Optimal combination of these parameters was obtained for achieving controlled machining of the work-pieces. Keywords: Electrical discharge machining, Response surface method, Electrode wear ratio, Mathematical Model.
