Experimental Investigation on H11 Steel In Abrasive Mixed EDM Process Using Aluminium Electrode for Surface Roughness

In this experimentation, various effects of input parameters in Electric Discharge Machining (EDM) process like polarity, peak current, pulse on time, duty cycle, gap voltage and concentration of abrasives powder in dielectric fluid are calculated experimentally for surface roughness investigation. A standard orthogonal array of L18 by Taguchi is used for experimental process. Al is used as tool electrode for the machining of H11 steel on Electronica Smart ZNC EDM. Main effects of factors are taken into account in this study. This study show result show the input process parameters are affecting the response variable i.e. (Surface roughness).
