Review on alternative approaches to fabricate the Copper based Electric Discharge Machining (EDM) electrodes

Abstract

Abstract Electric discharge machining (EDM) process is the category of the non-traditional and non-contact machining processes which is widely used in the industries for machining of difficult to machine materials and mainly utilized for fabrication of dies and high precision equipments. Machining performance of the EDM is mainly affected by the physical properties of the electrode. The ideal electrode of the EDM should have high electrical and thermal conductivity, high specific heat, better machinability and high wear and erosion resistance etc. A single material cannot fulfil all these requirements. This paper presents the review of alternative approaches to fabricate the electric discharge machining electrodes by using different process.
