Study of the Effect of Machining Parameters on the Machining Characteristics of Tungsten Carbide in Electrical Discharge Machine

Electrical discharge machining (EDM) is a widely used process in the mould / die and aerospace industries. It is a process for shaping hard metals and forming deep and complex-shaped holes by arc erosion in all kinds of electro-conductive materials. The objective of this research is to study the influence of operating parameters of EDM of tungsten carbide on the machining characteristics. The effectiveness of EDM process with tungsten carbide is evaluated in terms of material removal rate, the relative wear ratio and the surface finish quality of the workpiece produced. It is observed that copper tungsten is most suitable for use as the tool electrode in EDM of tungsten carbide.
