Multi-Objective Optimization of Inconel 718 Turning Parameters Using PCA-MARCOS and MARCOS-Taguchi

Abstract In recent years, multiple-attribute decision-making (MADM) methods have gathered significant interest from researchers across various scientific fields. the case of mechanical part machining when faced with conflicting objectives, these become essential in selection necessary cutting parameters. The integration techniques multi-objective optimization procedures has proven effective leading to an efficient solution a multi-attribute problem. present study falls within this context. Its primary objective being determination optimal parameters that reduces tool vibration, minimizes surface roughness along withmaximizing material removal rate during turning Inconel 718 using coated carbide grade (GC1105). These objectives been achieved through combining principal component analysis (PCA) method measurement alternatives and ranking according compromise (MARCOS), MARCOS coupled Taguchi SN ratio. results obtained demonstrated both generated same combination achieve aforementioned represented by nose radius r = 0.8 mm, speed Vc 70 mm min −1 , feed f 0.08 rev depth cut ap 0.3 mm.
