Abstract
From the last decade the electrical discharge machining (EDM) has been investigated as the process for surface modification besides machining. This paper describes the influence of W-Cu powder metallurgical electrodes at various parametric conditions on the surface of mild steel through electric discharge coating (EDC) process for its modification. Taguchi design of experiments is used to investigate the parameters which favour material transfer rate (MTR) with acceptable surface finish. Analysis of variance (ANOVA) and overall evaluation criteria (OEC) has been performed to the output parameters such as MTR and surface roughness
