This work deals with the optimization of 5-axis flank milling tool paths regarding the geometrical deviations and the trajectory smoothness. Our approach consists in integrating the energy of deformation of the tool path as a smoothness parameter in tool path computation. The resulting tool trajectory minimizes a compromise between geometrical deviations and smoothness in the part coordinate system. In order to assess smoothness in the machine coordinate system, an estimation of the minimum machining time is calculated accounting for the machine tool kinematical limits. Finally the proposed approach is assessed through experimental investigations.
