PROCESS PARAMETER OPTIMIZATION IN WIRE CUT EDM: A REVIEW

This paper describes a comprehensive literature review of major published research work performed on the Wire-Cut Electrical-Discharge Machining which is one of the widely used unconventional machining process in the manufacturing industry. Regarding the optimization of process parameters a lot of research work has been reported, but in unconventional machining processes obtaining higher metal removal rate with better surface quality is still a difficult task. Based on the literature reviewed, further research scope is identified. The present literature reveals that there is a further scope to optimize the various process parameters as well as effect of heat treatment of the work-piece material should be taken into account in order to get better surface quality of machined surface, dimensional accuracy and higher metal removal rate in wire cut EDM process for minimizing the machining time, power consumption and manufacturing cost.
