Abstract

In this paper, cutting of SS316 material using electro discharge machining (EDM) with a copper electrode using RSM technique is discussed. Electrical discharge machining (EDM) is one of the earliest non-traditional machining processes [1]. These methodologies are used to analyze the effect of each parameter on the machining characteristics and to predict the optimal choice for each EDM parameter such as peak current, gap voltage and pulse on time. It is found that these parameters have a significant influence on machining characteristics such as material removal rate (MRR). The optimal settings of the parameters is determined through experiments, planned, conducted and analyzed using response surface methodology (RSM) called a Box-Behnken design [2]. The results of analysis (ANOVA) explained the proposed mathematical model is significant and desirable within the predicted range of process and response parameters.
