Amélioration de la qualité des pièces usinées par interpolation directe du trajet sur surface

Abstract : Despite recent advances in technology and software, the High Speed Machining process of complex surfaces still has challenges to achieve simultaneously productivity and high surface quality. Two of them are the tool path generation and its treatment by the numerical controller during real-time interpolation. To date, the classical solution "CAM-CNC" imposes breaks in the digital chain, limiting the final results that are really reached. This paper proposes a unified method, named DTIS (Direct Trajectory Interpolation on the Surface), for multi-axis tool paths generation and interpolation within a HSM context. It avoids the geometrical deviations related to the description format of the tool path and to their jerk limited interpolation. Thanks to the development of an open CNC on the LURPA's 5-axis high speed machining center, it is possible to evaluate the improvements provided by such an approach compared to the usual process.
