Abstract
Copper and graphite are the commonly used tool materials in Electric Discharge Machining (EDM). The use of copper as tool material increases the material removal rate (MRR) of workpiece during EDM. However, the tool wear rate (TWR) of graphite electrode is less as compare to copper electrode. In the current work, an attempt has been made to find the performance of Cu-Gr composite material as EDM tool. Four EDM tools of different copper-graphite composition have been used to machine AISI 1020 mild steel. Both MRR and TWR have been considered to measure the performance of EDM. The results reveal that the increase of graphite percentage in Cu-Gr composite tool reduces TWR up to 83 % by reducing MRR 73%.
