Enhancement of material removal rate in EDM process using silicon carbide based strenx 900 steel

Abstract Material removal rate (MRR) plays an important role in metal industries. Its mainly depends on hardness, strength and toughness of the material. Light hardness materials are easily machined by conventional machining processes. High hardness materials are easily machined by unconventional machining processes. Electrical discharge machining (EDM) process is one of the effective methods to machine very hard materials. To achieve high material removal rate in very hard material is difficult and it takes more time. The silicon carbide-based strenx 900 steel is used as work material for this experimental investigation. The material removal rate has enhanced by modification of electrical circuit, powder mixed dielectric fluid and install oxygen arrangement. These additional facilities are used to improve the machinability characteristics and tool life of the EDM process.
