Recent Developments in Wire Electrical Discharge Machining

The tremendous growth of manufacturing industries and desired need of accuracy and precision has put a great importance on non-traditional machining processes. Metal and non-metals having properties like high strength, toughness, and hardness is generally machined by non-conventional machining methods. One of earliest non-traditional machining that is still in use and being effectively utilized in industries is wire electrical discharge machine. This machining technique gives a tough line of competition to conventional machining process like milling, grinding, broaching, etc. Cutting intricate and delicate shapes with accuracy and precision gives this machining technique an edge over other conventional machining and non-conventional machining processes. This chapter provides an insight to various research and prominent work done in field of WEDM by various scientists, researchers, and academicians. The chapter also emphasizes various advantages and disadvantages of different modelling and optimization methods used. The chapter concludes with some recommendations about trends for future WEDM researchers.
