Abstract

This article considers the study of cutting parameter on Kerf width using WEDM of Inconel 718. Three numerical parameters like voltage gap, feed rate, and current are being manipulated in this experiment. Designs of experiment are done by using the response surface methodology. ANOVA shows that feed rate heavily affect the size of Kerf width compared to other parameter used in this experiment. Optimization was done after the experiment has been validated by using the random parameter and optimized parameter. The error obtained when using random parameter is 5% and 4% for the optimized parameter. The best combination of parameter to optimize the Kerf width are fz 0.86 mm/min, V 41 V and I 7A in as to obtain a Kerf width of 325.119 μm.
