Abstract :
The present study aims to develop a mathematical model so as to predict material removal rate using response surface methodology in a wire cut electrical discharge machine. In order to establish a mathematical model concerning process parameters and material removal rate, a central composite rotatable design matrix is employed. It includes four variables with five levels. Moreover, the process parameters such as Pulse; on time, off time, peak current, and wire tension are changed accordingly in the process of the experiments. A comparative study is made between the theoretically predicted values of material removal rate and the observations from the experiment. Both the experimental and predicted values are found to be concomitant
