A study on capabilities of different electrode materials during electrical discharge machining (EDM)

Electrode material in the electro discharge machining (EDM) process plays an important role in terms of material removal rate (MRR), electrode wear rate (EWR) and surface roughness (Ra). The purpose of this research is to investigate the capability of different electrode materials: copper, aluminum...
