Abstract
The present study highlights a multi-objective optimization problem by applying utility concept coupled with Taguchi method through a case study in Electric Discharge Machining of D2 Steel by using Electrode produced by Direct Metal Laser Sintering using Directmetal20. The study aimed at evaluating the best process environment which could simultaneously satisfy multiple Surface Roughness requirements. As traditional Taguchi method cannot solve a multi-objective optimization problem; Taguchi’s Lower-the-Better (LB) criteria; individual response characteristics has been transformed into corresponding utility values. Individual utility values have been added finally to compute overall utility degree which serves as representative objective function for optimizing using Taguchi method. The study combined utility theory and Taguchi method for predicting optimal setting. Optimal result was verified through confirmatory test. This indicates application feasibility of the aforesaid methodology proposed for multi-response optimization in Electric Discharge Machining.
