Research and Development in Wire Electrical Discharge Machining(WEDM) :A State of An Review


Wire electrical discharge machining (WEDM) is being widely used for a long time for machining conductive work materials which are difficult to be machined by the main stream machining processes. WEDM has evolved from a simple means of making tools and dies to the best alternative of producing micro-scale parts. This could be achieved with high degree of dimensional accuracy and surface finish. This paper reviews the comprehensive history of WEDM process and its parameters, performance of measures and applications. The review of research literature focuses on machining of metal matrix composite (MMC) by WEDM and the possible trends for future research in this area.
