Electrochemical discharge machining: A review

Abstract

Electrochemical Discharge Machining is unconventional hybrid machining process which combines the features of electrochemical machining (ECM) and electro discharge machining (EDM). This machining process is able to machine hard and brittle non-conductive materials such as glass, ceramics, refractory bricks, quartz, composite materials and electrically conductive materials such as steel, copper, tungsten etc. Features with high aspect ratio and complicated geometry can be created by Electrochemical Discharge Machining. Electrochemical Discharge Machining (ECDM) find a wide range of applications in advanced industries like Nuclear reactor, Automobiles, Aeronautic, MEMS. This paper reviews various notable works related with the effective parameters of ECDM and optimization of parameters by different optimizing techniques, also gives future scope in the Electrochemical Discharge Machining.
