Orthogonal cutting models are described in this paper for the simulation of high speed hard turning, which has emerged as a very advantageous machining process for cutting hardened steels. The models are build using the finite element method and the commercial finite element code AdvantEdge, a special program used in the modelling of cutting. The influence of cutting speed, feed, rake angle and cutting edge radius of the tool on the performance of the cutting operation is investigated. Additionally, oblique cutting models of high speed hard turning are constructed, providing a different approach on the simulation of the process. From the results provided important conclusions are drawn indicating that the proposed models may be used for the studying of the process.
