Abstract

Electrical Discharge Machining (EDM) is a thermo-electric process which widely used in the manufacturing process for tool mould and die industries. Mechanism of EDM process is complex and difficult to understand. So, establishing a comprehensive model to predict the performance by correlating the process parameters is a difficult work. In the present work, a Central Composite Design (CCD) for combination of variables and Response Surface Method (RSM) have been used to explore the influence of process parameter such as; peak current, powder concentration and tool diameter on the Material Removal Rate (MRR) on EN-8 steel. Analysis Of Variance (ANOVA) at 95% level of significance was performed to obtain the significant coefficients. Significant process parameters have been identified and optimum process conditions have been obtained. A confirmation experiments has been conducted and verified optimal conditions. Percentage errors of predicted and actual values for developed models was found within 5%.
