Abstract

Powder-mixed EDM is a prominent methodology for enhancing surface quality as well as MRR. The objective of this experiment is to optimize the PMEDM process parameters for machining EN19 work piece by Cu electrode with tungsten powder additives. In this experiment, three levels of current, powder concentration, and pulse on time are kept as the main variables for which Taguchi single objective methodology has been adopted to design the experiment. ANOVA has been done to show powder concentration is the significant variable for high MRR. The conclusions arrived for an optimum value of different parameters has also been verified and the error was found to be 0.64 %.
