CURRENT RESEARCH TRENDS IN MICRO ELECTRICAL DISCHARGE MACHINING: A REVIEW

In recent years, rapidly developing technology required to develop products in miniaturized compact volumes with combineding more functions are embedded in the products. So to fulfill this requirement of technology industries has to implement advancement in manufacturing process. Micro holes will find very precise application in many areas. Hence manufacturing of such hole should be done very accurately. µ-EDM is one of the most efficient methods for fabricating precise micro holes with close tolerance. This paper reviews the vast array of research work carried out within past decades for the development of Micro EDM. This study is mainly focused on aspects related to metal removal rate, tool wear and dimensional accuracy which are the most important parameters from the point of view of selecting the optimum condition of processes as well as economical aspects
