Electric discharge machining (EDM) widely used mostly in the tool and die industry and the material normally used as electrode are copper, tungsten, graphite, copper tungsten and copper chromium alloys. In the present work, Electric discharge machining was carried on H-13 workpiece using powder metallurgy electrodes of copper chromium (CuCr) and conventional copper electrode. The input parameters selected in the study were current, voltage, duty cycle and retract distance. The output parameters were material removal rate, tool wear rate, surface roughness and overcut. Experimental results show that CuCr powder metallurgy electrode gives best results for MRR. Also CuCr powder metallurgy electrodes gives better results for overcut as compare to conventional copper electrode. It has been seen that electrode type is significant factor for all output parameters.
