3D FEM Investigation of the Effects of Nose Radius and Edge Radius on Turning of AISI 4140

摘要

In this paper, FEM is employed to investigate the effects of nose radius and edge radius on the turning of AISI4140. The tool material used is Carbide and Johnson-Cook plastic model is employed to model the workpiece due to its capability of modeling large strains, high strain rates, and temperature dependent visco-plasticity. Different nose radii and edge radii are used to explore the effects of the nose radius and edge radius on the machining temperature, cutting forces, and power. This model provides a fundamental understanding of cutting mechanics of the turning operation of AISI 4140.
