Abstract
To enhance the velocity profile’s smoothness and machining efficiency of continuous short line segments, a velocity smooth control algorithm was presented based on the transition of cubic parametric spline curves. The transitional mathematical model was constructed, and an improved S-shaped jerk-limited acceleration/deceleration algorithm with look-ahead was adopted for smoother velocity profiles. The simulation and experiment results showed that machining efficiency was greatly improved, and smoother velocity profile was achieved, which approved the feasibility and validity of the proposed method.Keywords
