Utility-Taguchi based hybrid optimization approach in machining of graphite composites

In the present scenario, composites material is widely used in various engineering areas like satellite components, aircraft parts, chemical and sports industries. Graphite an allotrope of carbon that possesses electrical mechanical properties. this paper, graphite taken as reinforcement into epoxy matrix. study, hybrid optimization module developed to tackle multi-objective machining performance issues. Utility concept coupled Taguchi approach find out optimum values responses three input factors i.e., drill speed, feed rate fiber volume percentage varied at four discrete levels surface roughness (Ra) removal (MRR) are process response. L16 OA has been perform operation. Multiple aggregated a single function overall utility (U) finally optimized by concept. embedded determined favorable setting which confirmatory test verified shows satisfactory results. ANOVA outcomes reveal (73.37%) most important factor trailed speed (3.44%) percentage.
