EDM process became industrially viable after the discovery of the influence of different dielectric on machining performance. Dielectric fluid used by different micro-electrical discharge machining operation has huge impact on the machining performance like MRR and surface finish. Earlier only hydrocarbon oil was used as dielectric that affects health safety and environment. Through this paper, authors present a literature review on the application of dielectrics which are better substitute to hydrocarbon oil and how hydrocarbon oil can also be used more efficiently. Some of the work depicts that water-based dielectrics can also be used in die sink EDM instead of hydrocarbon oil. Apart from liquid dielectric, micro-EDM is also possible in gaseous media such as oxygen, air, helium, and argon. But gas-assisted micro-EDM needs further more research to make it industrially viable.
