Abstract: Discusses the machining performance of different electrode materials,namely brass wire and zinc-coated wire,in Wire-Cut Electrical Discharge Machining(WEDM).The Material Remove Rate,surface roughness and surface topography had been selected as the performance indicators.The results showed that,compared to the brass wire,the zinc-coated wire could obtain the higher material remove rate,smaller surface roughness and better surface topography when machining the Ti₆Al₄V steel.

Key words: Wire-Cut Electrical Discharge Machining(WEDM), electrode wire, brass wire, zinc-coated wire
