NC-simulation for the prediction of surface finish in 5-axis High-Speed Machining

This paper deals with simulation models allowing predictions of the surface finish and the actual velocity during machining. To simulate material removal in 5-axis machining, we propose an N-buffer based model integrating the Inverse Kinematics Transformation. This model can be coupled with the NC-simulation model we have previously developed, and which has been validated for several sets of NC/machine tools. The tooth track is thus linked to the velocity giving the surface topography resulting from actual machining.
