Literature mapping of electrical discharge machining (EDM) system

Electrical Discharge Machining (EDM) is a non-traditional machining process used for end pieces in application of aerospace, automotive industry and many manufacturing industries. The process removes the material from a workpiece by a series of frequent electrical discharges between the electrode tool and the work piece in a dielectric fluid environment. Duet the non-direct contact between the workpiece and the electrode during the machining process, mechanical stresses and chatte vibration issues are eliminated.This paper presents a review of EDM particularly in control system, Material Removal Rate(MRR) and power generator design and development.
