Abstract: In this paper, an attempt has been made to review the literature on strategies formulated and tested in ultrasonic vibration assisted electrical discharge machining (USEDM). The strategies for optimisation of EDM performance include flushing, dimensional accuracy, cavitation, surface morphology, polluted gases and chemical effects etc have been highlighted. The major performance controllable parameters in EDM process have also been discussed in this study. The main emphasis is given on classification of USEDM process on the basis of mode of ultrasonic vibration (UV) action imparted to EDM system, which includes a tool, work piece and the dielectric medium. The ultimate purpose of this study is to generalise the variable relationships of various proposed strategies, which may be applied in industries to improve the performance of USEDM. At the end of this study, some limitations of implementing ultrasonic vibration in EDM have been discussed.

Keywords: UV action; mode of vibration; flushing; dimensional accuracy; cavitation; surface morphology; polluted gases.
