Analysis of Surface Integrity in Electrical Discharge Machining (EDM) Process for Tungsten Carbide Material

Abstract

The present work comprises of study conducted with a view to optimise the process parameters for machining of tungsten carbide (WC-Co) composite by EDM process. In order to improve MRR and also the surface roughness (R value), pulse-on time, the discharge current, electrode material and type of flushing were varied. The conclusions derived from the investigations are reported as below under separate heads.
