Influence of the Nose Radius on the Cutting Forces During Turning

The primary goal of this paper consists of developing a cutting force model in oblique longitudinal turning. A new method, based on the equivalent geometry of cutting tool, is proposed and included in a 3D thermomechanical model of cutting. Roughing and finishing turning operations were considered for validation. The predicted results are in line with experimental data over a wide range of cutting conditions. Besides, it is underlined that the proposed method represents a robust model taking into account tool-workpiece behavior, friction and it leads to reaching cutting force components quickly.
