Abstract

This work addresses the process of surface modification of aluminium workpiece in EDM process. Powder metallurgical green compact of macro-sized powders of copper (Cu) and nano-sized multi-walled carbon nanotube (MWCNT) are used throughout the surface modification process. The EDM process is carried out by varying the tool parameters, such as the compaction pressure of the green compacts, and process variable settings such as, peak current and pulse on-time setting. The experiments are planned and performed utilizing the Taguchi L9 orthogonal array. The highest MDR value of 0.36 mg/min and the lowest Ra of 2.5 μm achieved in the experimentation. The XRD analysis confirms the tool material's presence in the modified surface.
