Abstract
The present research aims at investigating the influence of the cutting conditions during hard turning of AISI 52100 bearing steel using two types of mixed ceramics with different geometries. The ceramic tools used were represented by the conventional mixed ceramics (Al2O3+TiC) of conventional shape (CC650) and Wiper (CC650WG). A Taguchi L16 experimental design was applied to explore the impacts of the conditions of cutting, specifically the speed of cutting (Vc), rate of feed (f), and depth of cut (ap) on the output parameters through a statistical approach based on (ANOVA). The analysis of the results obtained enabled the development of mathematical models that predict output parameters represented by the surface roughness (Ra) and the tangential cutting force (Fz) for the two ceramics tested. Three multi-objective optimization methods represented by the Desirability Function (
