Thermomechanical modeling of orthogonal cutting including the effect of stick-slide regions on the rake face

An orthogonal cutting model including the primary and secondary shear zones is pre-sented in this study. The primary shear zone is modeled by a thermomechanical model where the rake contact is represented by two regions of respectively sticking and sliding friction. The model is compared with experimental results in terms of shear stress, shear angle, and cutting force predictions. Overall a good agreement is observed.
