SIMPLE PREDICTIVE MODEL OF ORTHOGONAL METAL CUTTING.

The purpose of this paper is the extension of a previously boundary equilibrium model through the consideration of chip moment. The model includes the elastic components of the tool rake face force, which exerts considerable influence on the process. It has been shown that a very simple predictive model of orthogonal cutting leads to relationships between the machining variables which are in accord with previous findings. The assumptions which have been made to allow the construction of such a model have been minimized and shown to be in accord with experimental data.
