Past and Current Status of Hybrid Electric Discharge Machining (H-EDM) Processes

Abstract

A B S T R A C T Electric discharge machining (EDM) process is one of the highly used advanced machining process. The material removal mechanism is melting and evaporation electric discharge in EDM process. EDM process has its advantages and disadvantages. To overcome the disadvantages, many researchers are trying to hybrid this process with other process. So, that the hybrid EDM process clubs the advantages of both processes which can increase performance and efficiency compared to EDM process alone. This paper reviews the past and current status of various hybrid EDM processes.
