This study presents an investigation on wire electric discharge machining (WEDM) of pure titanium (grade-2). An attempt has been made to model the response variable dimensional deviation using the response surface methodology in a WEDM process. The experimental plan is based on Box-Behnken design. Six parameters such as pulse on time, pulse off time, peak current, spark gap voltage, wire feed, and wire tension were varied to investigate the effect on output response. The response has been optimized using the multi-objective optimization through desirability approach. The analysis of variance has been applied to identify the significance of the developed model. The test results confirm the validity and adequacy of the developed response surface methodology model. Finally, the optimum parametric setting is designed for the optimization of process .
