ABSTRACT:In this paper Silicon Carbide powders mixing into the dielectric fluid of EDM on machining characteristic of SS316 L materials has been proposed. Various process parameters namely peak current, pulse-on time, pulse-off time, powder concentration, powder grain size and nozzle flushing, duty factor, etc have been considered. The process performance is measured in terms of Response variables like Material Removal Rate(MRR) & Surface Roughness(SR). Number of experiments to be conducted is based on Taguchi orthogonal array with three level and three factors. The outcomes are expected to increase MRR, improve surface finish/reduce surface roughness..
