Abstract
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.
