Turning of polymers: a novel multi-objective approach for parametric optimization

摘要: Engineering problems often embodying with multi-response optimization may be confiscatory in nature. Multi-response basically correspond to choosing the ‘best’ alternative from a set of available alternatives (where can interpreted as ‘the most preferred alternative’ solutions). Manufacturing process involves machining parameters order improve product quality well enhance productivity. Quality and productivity are two important but contradictory while performing operations. mainly concerns on surface roughness machined part whereas is directly related Material Removal Rate (MRR) during machining. As finish (roughness average value) seemed inversely MRR, hence it becomes essential evaluate optimal cutting setting satisfy contradicting requirements The aim this study propose an integrated methodology state characteristics that competitive regards quality. Owing issue, present reporting philosophies viz. (i) PCA coupled TOPSIS (ii) utility based fuzzy approach combined Taguchi framework has been adopted for assessing favorable (optimal) condition polymers (Nylon Teflon, case studies).
