Experimental Study on Material Removal Capability with Vibration-Assisted WEDM

Abstract:

Wire Electrical Discharge Machining (WEDM) is a thermal process that involves melting and vaporisation of work material by a wire electrode in order to obtain the required size. The present work covers a study to improve the material removal rate (MRR) and to machining required slot size by varying frequency lateral vibration of wire while WEDM machining on AISI H13. The machining experiments were conducted by means of two electrode wire materials such as brass and zinc coated wires. The experiments mainly focused on surface integrity aspects like surface/sub surface microstructure, kerf width and surface roughness modification of surfaces machined with Wire Electrical Discharge Machining. The experimental results present the machinability of work material with WEDM process with varying frequency of vibration of wire electrode materials.
