Electrochemical discharge machining (ECDM) is a hybrid machining process that combines the possible characteristics of Electro Discharge Machining (EDM) and Electrochemical Machining (ECM) machining. In the present work, Quartz is used as work piece material and potassium hydroxide (KOH) as an electrolytic medium. Experiments were carried out by considering the three factors at three different levels. The input variables are Voltage, Electrolyte Concentration (EC) and Inter-Electrode Gap (IEG). The experimental response variable is Material Removal Rate (MRR). The process variables were analyzed and optimized using ANOVA from the Minitab 14 statistical tool. The response parameters are predicted by using Artificial Neural Network (ANN) and linear regression equation was generated to predict the experimental values. The results reveal that, voltage and electrolyte concentration have approximately equal percentage of contribution in achieving maximum MRR.
