Abstract and Keywords

Abstract: This paper introduces the T-S velocity curve model based on existing velocity planning algorithms. Following the completion of path planning using the trapezoidal velocity curve, the displacement and critical point velocity for each stage are determined. Subsequently, the acceleration and deceleration stages are transformed into S-shaped acceleration and deceleration curves using the Bézier curve to achieve velocity planning for the entire path segment. Simulation results demonstrate that the proposed algorithm effectively addresses the issue of flexible impact resulting from sudden acceleration changes while ensuring planning efficiency. Finally, the algorithm's advantage in suppression of vibration shock is validated through vibration signal acquisition. Physical printing experiments further confirm a significant improvement in the quality of the printed models.

Keywords: 3D printing; stepper motor; velocity planning; acceleration and deceleration curve; Bézier curve
