On the Influence of Electrical Discharge Drilling Parameters and Per-formance Measures of Inconel 718 Superalloy - a Study

摘要

Presently, with gamut of technologies available still the manufacturing industries are beleaguered by significant challenges from hard-to-cut materials like superalloys, ceramics, stainless steels, brass, carbides and fiberreinforced composites along with exact design requirements (i.e., superior surface finish, high precision, versatility, high strength, intricate geometrical properties, low thermal expansion and robustness, etc.) and economical operation. Conventional Machining Processes (CMP) requires cutting tools that are tougher than the workpiece and require direct interaction between the workpieces. These features of CMP lead to hardships in handling hard and fragile materials.
