The electrical and non-electrical parameters of EDM influence the performance of EDM. EDM is one of the widely used non-traditional machining process used for machine the hard materials which are difficult to machine by the conventional machining processes. In the past few decades EDM gains popularity because of its wide range of applications in the die-making, aerospace industry and other manufacturing sectors. It is also an alternative method of batch production when the conventional machining processes fail to machine a material. The development in the new hybrid techniques and new tool materials makes some new research scopes in the EDM. Lot of research has been done in EDM optimization, monitoring and its application area but still there are many research gaps which need further study. The aim of this paper to identify the effect of electrical and non-electrical parameters on the performance measures of EDM.
