Abstract
A predictive model for residual stresses in orthogonal cutting is presented. It uses process conditions as inputs and predicts surface and sub-surface residual stress profiles due to machining. The model formulation incorporates cutting force and cutting temperature predictions and utilizes those parameters to define the thermo-mechanical loading experienced by the workpiece. The stresses at the cutter edge hone and in the shear plane are considered in a rolling/sliding contact algorithm which admits kinematic hardening for non-proportional plasticity with subsequent stress relaxation to meet boundary conditions. Model predictions are compared to experimentally-measured residual stresses under various cutting conditions for validation.
