Electrical discharge machining of titanium alloy using copper tungsten electrode with SiC powder suspension dielectric fluid

Titanium alloys which are categorized as lightweight materials, posses greater strength and toughness are usually known to create major challenges during conventional and non-conventional machining. Electrical discharge machining (EDM) which is very prominent amongst the non-conventional machining m...
