3D Hybrid Numerical Model of Residual Stresses: Numerical—Sensitivity to Cutting Parameters When Turning 15-5PH Stainless Steel

This paper investigates the residual stresses induced by a longitudinal turning operation in 15-5PH martensitic stainless steel. An experimental investigation has quantified sensitivity of to cutting speed, feed, tool geometry and flank wear. In parallel, 3D hybrid model, previously developed, been applied each case study. modelling approach consists replacing tooling chipping equivalent thermal mechanical loadings. These loadings are moved onto machined surface compute final stress state. It shown that wear have dominant effect on compared speed feed rate. However, influences intensity compressive peak, some extent, whereas affected depth. work also model is able predict stresses, as well parameters, with reasonable agreement.
