    The process parameters of such process should be optimized to improve the quality measures. In the present study, Taguchi- DEAR based multi criteria decision making has been proposed to obtain optimal combination process parameters on machining die steel in PMEDM process. From the experimental investigations, the optimal process parameters combination has been found was found as SKD11 (workpiece), Gr (Electrode), positive (polarity) and 20 µs (pulse on time), 8A (current), 57 µs (pulse off time) and 20 g/l (Powder concentration) among the chosen parameters in the machining process.
