Optimization of Material Removal Rate and Surface Roughness for EN31 Steel in Wire-EDM Process

R. Santosh Kumar, A. Balaram Naik

Abstract: In the present work an attempt is been made to optimise the performance parameters of wire-cut electric discharge machining on EN31 alloy steel, this is achieved by adjusting the input parameters. Non-electrical input parameters are chosen in the experiment and they were wire feed-rate, wire tension, duty factor and dielectric pressure. Here fractional factorial method is used for design of experiment and trails were conducted based on it. The data obtained from the experimental trails is utilised to deduce optimum input parameters for best machining performance based on greys relational analysis. And finally the influence of each parameter chosen for the experimentation is also established.
