Abstract

Electric discharge machining (EDM) process with conductive metallic powder has been widely employed for hard materials machining with acceptable dimensional and geometrical accuracy. However, low material removal rate (MRR) and poor surface quality limits the applications of this machining technique. In this article, effort has been made to identify the parameters that resulted in maximum MRR and minimum overcut (OC) during EDM operation of various die steels having similar applications (EN8, EN19 & EN24) by copper electrode with nickel powder-mixed dielectric fluid. Since the MRR in EDM process has been affected significantly by variation in peak current, off and on time of pulse, so these three parameters along with concentration of conductive powder have been selected as input variables in the research work. The experiments were executed and analysed using RSM technique of design of experiments.
