Abstract: Rapid advancement in manufacturing industries has given rise to miniature and light weight products with increasing high engineering applications. Micro-EDM is one of the most extensively used chipless machining processes to fabricate desired product features. In recent years, many researches have been directed to enhance the performance of micro-EDM. This paper provides such a review on the research activities carried out in the micro-EDM process. The influence of dielectric fluids, pulse characteristics and ultrasonic vibration which play a vital role in the machining performance of micro-EDM are highlighted in this paper. Also attempts made by various researchers to fabricate a high aspect ratio micro-structure using micro-EDM are discussed. Hence, a consolidated review of this research work will enable better understanding of the various contributions for effective implementation/application. The review also focuses on the optimisation of various parameters using different methods viz., Taguchi, ANN, grey relational analysis and fuzzy logic control system.

Keywords: micro EDM; dielectric fluids; pulse duration; ultrasonic vibration; material removal rate; MRR; tool wear; optimisation; Taguchi methods; artificial neural networks; ANNs; grey relational analysis; GRA; fuzzy logic; fuzzy control; electro-discharge machining.
