Prediction of shear angle variation in orthogonal wave-removing processes

Abstract

An analytical model is presented for predicting the dynamic response of the shear plane during an orthogonal wave-removing process. The model is derived based on the work-hardening slip-line field theory in cutting mechanics. It takes into consideration the variations of the hydrostatic stress along the shear plane and the mean frictional coefficient on the tool-chip interface in response to the change in the cutting configuration. The results from a series of simulation studies show that the predictions from the model are in very good agreement with the existing experimental evidence for a wide range of cutting conditions.
