One of the most important nontraditional machining processes is wire electrical discharge machining which is used for
machining of conductive materials with high precision. Monel R- 400 material is selected for finding the optimal machining
parameters on Wire-EDM, Monel R-400 materials are widely used in marine applications, oil production and refining
industries. The input process parameters taken into consideration are the pulse on time (Ton), pulse off time (Toff), peak current
(I), and wire feed (WF) and the data is collected through experimentation. The output response such as material removal rate
(MRR) has been considered for analysis. Taguchi L27 design is used to conduct the experiments, and response surface
methodology is applied for the development of the MRR model and optimization of response
