摘要：

This paper deals with assessment and correction of tool path in 5-axis machining. The tool trajectory is described using two curves; each one corresponding to the trajectory of two particular points of the tool axis. The assessment of the tool path is performed via the calculation of the envelope surface, which is calculated using a kinematics approach. The geometrical deviations between the envelope surface and the nominal surface are calculated. When necessary, the tool path is corrected, so that the envelope surface fits the ideal surface as much as possible. This correction is carried out by the deformation of both curves that are representative of the tool trajectory. We choose to illustrate our purpose through flank milling of sculptured surfaces.
