Wire cut EDM (WEDM) is a thermo electric nontraditional manufacturing process in which material isremoved by localized heating and melting. It is discrete spark generation method applicable for hard and difficult tomachine materials. In this paper mathematical model developed for EN19 material with Stastical analysis software.Experiments are carried out using L27 Orthogonal array by varying Material Thickness, pulse on time, Pulse Off time,Flushing Pressure, Wire Tension and Servo voltage. Analysis found that varying parameters are affected for consumablewire with constant wire feed in different way for different response. Attempt to compare different order mathematicalmodel for accurate modeling done in this research. Higher order mathematical model developed with R2value 0.9863 forMRR and 0.9918 for Surface roughness obtained which gives more accurate output for given input parameters.
