Multi-criteria decision making of turning operation based on PEG, PSI and CURLI methods

Multi-criteria decision-making ( MCDM ) is the methods identify an alternative that considered best among implemented alternatives. This issue probably more significant since each evaluated based on many criteria may be contrary. paper presents multi-criteria of a turning process. Turning experiments were carried out with total sixteen A test material used SB410 steel. Cutting tools are coated TiN. The aim this study to determine experiment where minimum surface roughness and maximum removal rate MRR) simultaneously obtained. Three include: Pareto-Edgeworth Grierson PEG ), Preference Selection Index PSI Collaborative Unbiased Rank List Integration CURLI ). In case application, it not necessary define weights for criteria. stability ranking alternatives basis different also identified according value Gini index. results demonstrate both option. cutting velocity 1700 rev/min, feed 0.192 mm/rev depth cut 0.6 mm options MRR respectively.
