ABSTRACT
This paper describes the development of a response model for electrical discharge machining inconel X750 utilizing response surface methodology. The metal removal rate (MRR), models are developed in terms of Pulse peak current (Ip), Pulse on time (Ton), Gap voltage (V).The contours have been generated from these model equations and are shown of different plots. The model generated shows that the metal removal rate increases with an increase of pulse on time, and relatively with gap voltage. Metal removal rate decreases when pulse peak current increases.The second order is more accurate based on the variance analysis and the predicted value is closer to the experimental result.
