Abstract: Electric Discharge Machining has been established as standard process for machining of electrically conducting hard materials. The intrinsic nature of the EDM process results in electrode wear while machining the workpiece. The electrode wear rate as response parameter is required to be studied for maximum performance of the electrode while machining the work piece. Therefore it is desired to find the effect of EDM process parameters on the Electrode wear. The experiments have been performed with Cu-Mn composite material electrodes on hardened EN-31 die steel as work piece. The composite material electrodes were made through the process of powder metallurgy with different ratio of Cu-Mn metallic powders. It has been observed that Copper-Manganese composite material electrode made with 80-20 weight ratio gives less electrode wear rate as compared to copper-manganese (weight ratio 70-30) composite material electrodes for machining of work piece
