Abstract
The use of unconventional machining techniques in shaping metal matrix composites (MMCs) has generated considerable interest as the manufacturing of complicated die contours. Metal matrix composites are advanced materials having high specific strength, good wear resistance, and high thermal expansion coefficient. Electrical discharge machining is a best process to make complicated shapes on the difficult to machine materials. The current paper presents a review of the research work done in electrical discharge machining (EDM) on MMCs. The review is categorized in to two stages namely wire cut EDM on composites and EDM on composites .This literature review helps to identify the suitable process parameters and their ranges in machining of composites.
