An analytical computer program, called OXCUT, is developed at the ERC/NSM to predict forces, stresses and temperatures in orthogonal and practical cutting operations from flow stress and thermal property data of the workpiece material, tool geometry and cutting conditions. The temperature and force results, predicted by OXCUT, are compared to the measured results published in the literature. Moreover, orthogonal slot milling experiments in conjunction with OXCUT and multidimensional minimization are used to obtain flow stress data for metal cutting. The obtained flow stress data are input to FEM(DEFORM) to study the influence of edge preparation (hone/chamfer) of cutting inserts on insert stresses and cutting temperatures during orthogonal turning of H13 tool steel (46HRC). Furthermore, the stress, temperature, and relative velocity results, predicted at the tool-workpiece interface using OXCUT, are utilized in an attempt to study the influence of tool geometry and cutting conditions on tool wear in drilling.
