Surface Study in a Non-conventional (Electrical Discharge Machining) Process for Grade 6 Titanium Material

Electrical discharge machining (EDM) produces complex shapes and permits high-precision machining of any hard or difficult-to-cut materials. The performance characteristics such as surface roughness and microstructure of the machined face are influenced by numerous parameters. The selection of param...
