Article: Assessment of turning performance of POM-C and PA.6 using Taguchi, VIKOR, TOPSIS and CoCoSo methods, incorporating AHP and FUCUM Journal: International Journal of Manufacturing Research (IJMR) 2024 Vol.19 No.4 pp.418 - 454 Abstract: Despite their widespread use in modern manufacturing for producing mechanical parts, the machining of unreinforced polymer materials like PA-6 and POM-C has received limited attention in the existing literature. The distinctive semi-crystalline nature of these materials necessitates specific machining approaches. This investigation aims to address this gap by focusing on process control for machining polymer parts, targeting optimal cutting parameter configurations for shaping processes. The parameters include cutting speed (Vc), feed rate (f), and depth of cut (ap), while outcomes such as surface roughness (SR), tangential cutting force (Fz), cutting power (Pc), and material removal rate (MRR) are evaluated. Single-objective optimisation was conducted using the Taguchi philosophy, and three multi-objective MCDM methods (VIKOR, TOPSIS, and CoCoSo) were used. The findings indicate that the VIKOR method outperforms the others, achieving a favourable compromise among the objectives. By incorporating the AHP and FUCOM weighting methods, The TOPSIS and CoCoSo methods strike a balance between product quality (Fz and Ra) and productivity (MRR and Pc).
