What is A multivariate hybrid approach applied to AISI 52100 hardened steel turning optimization about?

This paper presents an alternative hybrid approach, combining response surface methodology (RSM) and principal component analysis (PCA) to optimize multiple correlated responses in a turning process. Since a great number of manufacturing processes present sets of correlated responses, this approach could be extended to many applications. As a case study, the turning process of the AISI 52100 hardened steel is examined considering three input factors: cutting speed (V c ), feed rate (f) and depth of cut (d). The outputs considered were: the mixed ceramic tool life (T), processing cost per piece (K p ), cutting time (C t ), the total turning cycle time (T t ), surface roughness (R a ) and the material removing rate (MRR). The aggregation of these targets into a single objective function is conducted using the score of the first principal component (PC 1 ) of the responses' correlation matrix and the experimental region (Ω) is used as the main constraint of the problem. Considering that the first principal component cannot be enough to represent the original data set, a complementary constraint defined in terms of the second principal component score (PC 2 ) is added. The original res
