A new constitutive model for cutting simulation of 316L austenitic stainless steel
Paper in proceeding, 2019

In this study, a new phenomenological model is proposed to describe the flow stress properties of 316L austenitic stainless steel at high strains strain rates and temperatures encountered in metal cutting. Additionally, a novel approach is presented for calibration of the proposed model which combines the experimental flow stress data with inverse modelling of the orthogonal cutting process. The simulation results including the cutting forces and chip shapes are compared with the experimental results attained using tailored tools with different rake angles. This model showed improved prediction capabilities in comparison with those obtained from the widely used Johnson-Cook material model.
