Abstract: A real-time velocity planning algorithm is proposed to improve the processing accuracy and efficiency of small line segments. The algorithm consists of two parts: a dynamics-based preliminary planning algorithm is proposed to optimize the actual acceleration of short line segments and improve the smoothness of motion, addressing the jitter problem of rigid-flexible coupling and heavy-load platforms in numerical control (NC) motion; a dynamics-based adaptive multi-segment look-ahead velocity planning algorithm is proposed to enhance processing efficiency for small straight lines/arcs, addressing the inefficiency issue of the single-segment look-ahead algorithm. The algorithm was tested on a PC-based real-time controller and a gantry dual-drive XY laser cutting platform and was compared with the adaptive feed-rate algorithm and single-segment look-ahead algorithm. The results show that the proposed algorithm improves both processing quality and efficiency. Additionally, the algorithm is simple and effective, and thus suitable for high real-time application environments.
