Abstract
The Experimental Investigation of machining and mechanical characteristics ofTungsten carbide/Cobalt (WC/CO) composite,which is a vital composite material employed for manufacturing the largely universal and thriving dies, cutting tool as well as other special purpose tools. It is not possible to machine this machine this material easily through conventional techniques that is why the electro - discharge machining (EDM) is used for machining of WC/CO based material, which is produced through powder metallurgy route.It has been carried out on the influence of parameters factors such as Electrode rotation (S), Pulse on time (T) Flushing pressure (P), Current(C) and voltage (V) of EDM were chosen as input variables to optimize the process performance characteristics in terms of material removal rate (MRR) and surface roughness (Ra).The Response Surface Methodology (RSM) was used to identify the most important parameters to maximize the material removal rate and minimize the surface roughness.In this paper study to focus on optimization of EDM characteristics of tungsten carbide/cobalt based composites.
