ABSTRACT: Wire electrical discharge machining is process to cut difficult material for manufacturing the complicated parts and shape. In this research empirical model is develop for material removal rate considering the input parameter like pulse on time ,pulse off time, peak current, servo voltage ,wire feed rate, wire tension ,wire material. L27 orthogonal array were used to perform the experiments. Simplex and quasi newton method used to determine power indices and constant. Predicated and experiment value of material removal rate is approximately near. It was found that wire diameter and pulse on time is most significant parameter.
Keywords : Wire electrical discharge machining; Orthogonal array; Simplex and Quasi newton method.
