An overview to micro-wire-electrical discharge machining

Abstract

Abstract Hard to cut metals are widely machined with the help of Wire EDM process which overcomes major challenges in the conventional machining processes. For generation of micro-features and complex three dimensional structures Wire EDM is considered above other unconventional machining process like abrasive jet, laser, plasma and electron beam machining. Wire EDM provides better dimensional accuracy, machining rate and surface finish, with flexibility to alter process parameters. Importance and utilization of micro or nano parts in aerospace, medical, missiles & ballistics and automobile requires machining process like μ-WEDM to obtain desired features and intricate geometries. This study approaches and enlightens the work areas where micro level features have been generated using Wire EDM by different researchers, using diverse experimentation, modeling and optimization approaches for Wire-EDM. Finally, conclusion and future scope at the completion of the chapter binds up the present study.
