Effect of Powder Mixed Electrical Discharge Machining (PMEDM) on Difficult-to-machine Materials – a Systematic Literature Review

Abstract

AbstractThe last decade has witnessed an increasing interest in the novel applications of electrical discharge machining (EDM) process. Due to the continuous efforts by the researchers many innovations have been made to improve the performance of EDM process. Among various EDM variants, powder EDM is one of the successful technique, which shows the considerable improvement in the performance of EDM by increasing the MRR and surface finish as both of these responses are mainly considered by the industries. Despite the better processing results, powder mixed EDM process is used in industry at slow pace. Therefore, with a vast future scope of powder EDM in areas of machining and surface modification of difficult-to-machine materials, authors in this paper explored all the parameters and terms related with powder mixed EDM process. The main aim of the paper is to help the researchers to understand this concept thoroughly and research the process parameters further in more details to get more improvements in the process resulting in achieving desired quality levels.
