Ultimate Tensile strength and wear resistance of fabricated copper-based composites is improved at the higher reinforcement content. Founded in 1980 to provide a specialist sub-contract Wire and Spark erosion service to the engineering industry. EDM. 0000024927 00000 n Electrical Discharge Machining (EDM) is a competitive technology for this operation, since it does not depend on material hardness and can fulfill strict geometrical requirements. Numbers of ways are explored by researchers to improve and optimize MRR along with a reduction in tool wear rate (TWR) and surface roughness (Ra). Electro discharge machining (EDM) is one of the most widely used non-conventional and contactless technologies for the manufacturing of materials featuring electro-conductivity, high hardness and strength. manufacturing sectors. Electrical Discharge Machining. In Electric Discharge Machining process an arc is produced when two current-carrying wires are short-circuited.
