Wire Electrical Discharge Machining (WEDM) is a specialized thermal machining process capable of accurately machine parts with varying hardness or complex shapes and are very difficult to machine by conventional machining processes. This study outlines the development of model and its application to optimizing machining performances such as machining time and surface quality using Desirability Function Approach (DFA). The design matrix for the experiments is developed on the basis of 1/3 Fractional Factorial Design with no replication. Each experiment has been performed under different cutting conditions of pulse-on time, pulse-off time, peak current and spark gap set voltage. A composite desirability value is obtained for the multi-responses using individual desirability values from the DFA. Based on composite desirability value, the optimal levels of parameters have been identified. The optimal process parameters for individual response is also obtained by using Taguchi’s signal to noise (S/N) ratio.
