A comparative study on work surface hardness EDMed by Ta-C powder compacted and copper electrodes

Abstract. Tantalum-carbide and solid copper electrodes were used to EDM mild steel. Current, spark on-time and off-time were taken as the machining variables. It was found that work surface hardness increases while machining with high current and on-time. However, increase in spark off-time results...

Metalworking Abstract. Tantalum-carbide and solid copper electrodes were used to EDM mild steel. Current, spark on-time and off-time were taken as the machining variables. It was found that work surface hardness increases while machining with high current and on-time. However, increase in spark off-time results decrease in work surface hardness. It was also found that the surface machined with pure copper electrodes is harder than that machined by tantalum-carbide powder metallurgy compacted electrodes.
