Study on the Strategies for Fabrication of Die Assembly with Typical Shaped Cavity by Using Electrical Discharge Machining

Article Preview

Abstract:

Die assembly is a kind of special tools for fabrication of metal or non-metallic materials parts with required design and purpose. Generally, the high material hardness for die assembly should be selected to increase the service life and reduce the cost in manufactory industry. Electrical discharge machining (EDM) is a suitable method for fabrication of die assembly as the material remove in EDM process mainly depends on the material's thermal characteristics, regardless of the hardness. In this paper, the machining strategies for fabrication of die assembly with typical shaped cavity using EDM were discussed, according to the different cavity structures, the best machining strategies were proposed
