Abstract

Abstract. During EDM work surface roughness can be influenced by using powder compacted electrodes. The present study shows that surface roughness of workpiece is higher when using TaC/Cu green compacted electrode compared to that produced by pure copper electrode. When using TaC/Cu green compacted electrode, more material is deposited on the workpiece surface and a thick layer is formed on the surface. In addition, the particles from the electrode are randomly deposited on the workpiece surface. On the contrary, there will be only a very thin layer of material from electrode will be deposited on the workpiece surface when using pure copper electrode. A thick deposited layer with randomly deposited particles will create rougher surface rather than a thin layer. That is why surface roughness is high when using TaC/Cu green compacted electrode.
