The present experimental investigation is conducted on EDM is performed on AISI 4140 or EN-19 as workpiece with
copper as electrode (tool) to establish the relationship between process parameters of EDM on material removal rate, tool wear
rate and radial overcut. Depth of machining is also considered as a process parameter in this investigation. The investigation
concluded that material removal rate, tool wear rate and radial overcut were majorly influenced by the peak current and depth of
machining. Pulse on time was found to be the least dominating parameter for all the performance measures.
