ABSTRACT

A simple erosion model for electrical discharge machining (EDM) is proposed and compared to other authors' cathode experimental data. From these comparisons, the effective arc spot current density and erosion enthalpy have been obtained. The good agreement between the experimental results and the theoretically calculated erosion curve validates the model.
