Abstract

This paper deals with finding five optimal control parameters input voltage, current, speed, pulse on/off time to maximize metal removal rate (MRR) and minimize surface roughness (SR) on wire edm (electrical discharge machining). Wire edm is an electro thermal production process in which a thin single strand metal wire in conjuction with de-ionised water (used to conduct electricity), allows the wire to cut through metal by the use of heat from electrical sparks. For the purpose to get a best solution to maximize MRR and reduce SR, here we optimize parameters using taguchi method. Also we compare experimental reading with taguchi optimum result to know the optimal solution.
