چکیده
In this study, the effect of input parameters of Electro Discharge Machining (EDM) process including polarity, peak current, pulse on time, duty cycle, gap voltage and concentration of abrasives powder in dielectric fluid on surface roughness are experimentally investigated. A L18 Taguchi’s standard orthogonal array is used for experimental design. Copper is used as tool electrode to machine H11 steel on Electronica Smart ZNC EDM machine tool. Main effects of factors are considered in this work. The results show that all the input process parameters affect the response variable (Surface roughness).
