Abstract :

Copper tungsten (Cu-W) metal matrix composite (MMC) is a very useful material for electrical discharge machining (EDM) electrodes. It has high strength, good wear resistance and exceptional arc erosion resistance. It is often fabricated using powder metallurgy route and is too hard to be machined with conventional techniques. In this paper, an attempt has been made to investigate machinability aspects of Cu-W with 30 wt.% copper and 70 wt. % tungsten in WEDM. The effects of Pulse on Time (Ton), Pulse off Time (Toff), Peak Current (IP), Wire Tension (WT) and Spark Gap Set Voltage (SV) have been investigated experimentally on Material Removal Rate (MRR) and Surface Roughness (Ra).
