Predictive model for the full biaxial surface and subsurface residual stress profiles from turning

A model to predict the fill biaxial surface and subsurface residual stresse s from the turning process is presented. The model formulation includes the rmomechanical coupling, plastic heating, frictional heating, convection, co nduction, thermal softening and strain hardening. Calibration and validatio n of the model are undertaken. The predictive model stands as a tool both t o optimize the turning process based on the resulting residual stresses and also to gain an in-depth understanding of the physics of residual stress d evelopment from the turning process. In addition, thorough analysis of the experimental results reveals insight into the effects of feed and depth of cut on the surface and subsurface machining-induced residual stresses.
