Effect of powder concentration on EDM performance during machining mild steel

This research work describes the effect of powder concentration in dielectric fluid during electrical discharge machining (EDM) of mild steel on material removal rate (MRR), electrode wear rate (EWR) and work surface roughness (Ra). The machining parameters studied in this research are current (4.5A...
