This paper outlines the findings of the investigational studies performed to explore the impact of the electrical discharge machining method and input variables on the properties of the output parameters. EDM allows the machining of very hard and high temperature resistant metals and alloys such as super-alloys, carbides, ceramic, composites and heat-resistant alloy. However, these products are challenging to produce owing to the need for higher cutting strength and large machine usage costs. EDM offers a minimal machining force with an appropriate tooling expense is a promising non-conventional machining method for machining Composites. As electrical erosion method is commonly used for the manufacturing of composites with further uses in the construction, aircraft and automotive industries. Composites have desirable physical as well as mechanical properties such as light weight, high specific modulus, higher toughness and Strength and thermal resilience. Due to wide range of application of composites nowadays the present analysis addresses the EDM and its input and output parameters such as Ton, Toff and Discharge Current, etc. on the MRR and SR especially for the composites. The goal of this paper is to examine past work and to establish a path forward for study.
