Abstract: A multi parameter analysis of Metal removal rate imparted to WC-Co by wire electro-discharge machining (WEDM) is presented. Wire Electrical discharge machining (WEDM) is a nontraditional, thermoelectric process which erodes material from the work piece by a series of discrete sparks between a work and tool electrode immersed in a liquid dielectric medium). This paper presents a detailed model of a WEDM. The structure includes in the model, are three parameters such as pulse on time, pulse off time, peak current. We analyzed the effect of this three parameters on material removal rate. The detailed mathematical model is simulated by Minitab14 and simulation results fit experiment data very well this shows that the model can be used to forecast the performance of WEDM when design. In this investigation, an effective approach based on Taguchi method, analysis of variance (ANOVA), multivariable linear regression (MVLR), has been developed to determine the optimum conditions leading to higher MRR. Experiments were conducted by varying pulse on time, pulse off time, peak current using L9 orthogonal array of Taguchi method. The present work aims at optimizing process parameters to achieve high MMR. Experimental results from the orthogonal array were used as the training data for the MVLR model to map the relationship between process parameters and MMR the experiment was conducted on WEDM. From the investigation It concludes that pulse on is most influencing parameter followed by pulse off time and peak current on MRR.
