Abstract

EDM is a non-conventional thermo electric process wherein material erodes from the workpiece by a series of discrete sparks between the tool and workpiece immersed in a dielectric medium. This discharge occurs in a voltage gap between the electrode and workpiece. Thermal analysis is essential to quantify the material removal rate and also to know the performance of the material with respect to the defined process. A substantial research has been carried out to qualify the material under process. However, due to complex processes involved an advanced analysis is mandatory. Present study explains how one can understand the behavior of a workpiece for participating in EDM process. Thermal analysis model accurately predicts the temperature profile, material removal rate and quality of the product. The basic objective of this paper is to explore the thermal analysis of the material in terms of a workpiece in EDM.
