Abstract
This paper presents the simulation of orthogonal metal cutting of 6061 T6 Aluminium alloy using Hypermesh and LS-Dyna to study the effect of the edge radius on cutting forces and chip formation. The constitutive material model Elastic Plastic Hydrodynamic was used to model the work piece. The capability of this model to predict cutting forces, shear angle and chip curvature was investigated. Design of Experiments principle was used to study the effect of the parameters on cutting edge performance. The trends of the simulated results were in good agreement with the generally observed theoretical and experimental results. The model can also be used as a numerical tool for optimizing the edge radius. The effect of edge radius and other cutting conditions on the chip curl and the shear angle were also investigated.
