ABSTRACT: Electrical discharge machining (EDM) is one of the earliest non-traditional machining
processes. EDM process is based on thermoelectric energy between the workpiece and an
electrode. Material removal rate (MRR) is an important performance measure in EDM process.
Since long, EDM researchers have explored a number of ways to improve and optimize the MRR
including some unique experimental concepts that depart from the traditional EDM sparking
phenomenon. Despite a range of different approaches, all the research work in this area shares
the same objectives of achieving more efficient material removal coupled with a reduction in tool
wear and improved surface quality. The paper reports research on EDM relating to
improvement in MRR along with some insight into mechanism of material removal. In the end of
the paper scope for future research work has been outlined.
