In this paper, we will review research work done in past regarding optimization of EDM process parameters by different techniques. It is observed that a review of the diverse approaches developed previously would aid to assess their foremost prospects and their advantages or boundaries in which the majority of materials have to be machined so as to choose the most appropriate approach for a meticulous application based on the material and also tells about the prospects that need further consideration. A substantial work has been reported by the researchers on the EDM performance for various materials on the basis of parameters. Numerous approaches are proposed in the past to resolve the problems such as to optimize the condition of higher MRR, and improvement in surface finish and lower SR with low tool wear rates are achieved with various optimization techniques. The vital electrical discharge machining parameter affecting to the characteristic measures of the course is Ip, arc gap, Ton, and Toff. Majorly electrical discharge machining parameters are usually evaluated on the basis of surface roughness (SR), MRR (MRR), cutting speed (V), and tool wear rate (TWR). Principle behind EDM process is thermo-electric source between the job and an electrode. The various process of EDM: die sinking EDM, wire EDM (WEDM), EDM milling, and wire electrical discharge grinding (WEDG). Electric discharge machining (EDM) is a vital non-traditional process, which is extensively used for machining a range of difficult-to-machine material such as heat-treated tool steels, composites, ceramics, carbides, heat-resisting steels with convoluted shape.
