Experimental investigation of Aluminum alloy 6061 machining in Powder Mixed EDM

Rakesh Kumar Patel, M. K. Pradhan.


Powder mixed electric discharge machining process (PM-EDM) is a hybrid machining process uses conductive and nonconductive micron/nano powder particle in the dielectric medium. The aim of this article is to find the optimum machining parameter for PMEDM of Aluminum alloy 6061. The selected input process parameters are voltage, peak current, pulse on time, and concentration of SiC powder. Taguchi method L9 orthogonal array used to plan the experiment. Multi optimization genetic algorithm used to find the optimum value of input parameter which gives better surface finish.

Key words: Powder mixed electric discharge machining process (PM-EDM), micron/nano powder, Aluminum alloy 6061
