High-performance NC for high-speed machining by means of polynomial trajectories

To answer both constraints, a good geometrical description of the surface and a better follow-up by the numerical control unit, this paper deals with polynomial formats for

Based on the feed drive model developed in the previous sections, the following section presents the results of simulation with the predictive RST control structure

By integrating kinematics performances, this model allows the simulation of the actual tool follow-up during machining, both at the kinematical level of each axis

In the case of ball-end cutter tool milling, for a given position of the tool center point any orientation of the tool axis preserves the tangent contact between the tool and
