Optimization of Machining Parameters for Electrochemical Discharge Machining for Soda Lime Glass

Abstract

In this study machining of soda lime glass with the help of copper electrode (cathode) and stainless steel (anode) electrode has been done. The electrolyte used was a mixture of sodium hydroxide and potassium oxide of specific concentration. An orthogonal array of L27 has been designed for the different input parameters such as voltage, electrolyte concentration and current. From the experimental study it was found that the applied voltage has the maximum influence on the responses that is material removal rate (MRR) and tool wear rate (TWR). Highest value for MRR was obtained at an applied voltage, electrolyte concentration, current of 70 V, 35 wt% and 6A respectively & TWR was minimum at an applied voltage, electrolyte concentration, current of 60V, 25 wt% and current was 6A respectively.
