An experimental investigation of gold coated silicon using nano powder mixed micro-wire electro discharge machining

Micro Wire Electro Discharge Machining (µ-WEDM) is a type of electro-discharge machining (EDM) process where wire is used instead of a rigid tool. It is a reliable and precise machining process, which is commonly used to produce various complex structural shapes for a wide range of industrial applic...
