Abstract

Wire cut Electrical Discharge Machining (WEDM) is one of the non-conventional machining processes capable of accurately machining components with high hardness and complex shape, which have sharp edges that are very difficult to machine by the conventional machining processes. A significant amount of research has gone into exploring different methods of achieving the ultimate WEDM goals of optimizing numerous process parameters analytically. This paper reviews the vast array of research work carried out by the earlier researchers and graded their results as the influence of machining parameters, pulse classification, effect of wire electrode parameter on machining criteria, thermal load on wire electrode, parametric optimization and adaptive systems. From the study carried out from the literature the optimum values of various machining parameters are notified in this paper. Future scope of the research work to be carried out is envisaged.
