摘　　要：为解决数控系统处理连续微线段时启停频繁以及插补过程中加速度突变等问题,通过建立圆弧过渡转接模型,根据转折点处的约束条件规划出过渡圆弧处的最优衔接速度,基于新型柔性加减速控制算法对多轨迹段进行速度前瞻规划。经过实验验证,该前瞻插补算法输出的轨迹误差不超过系统给定的最大值,且速度和加速度曲线连续平滑,在满足加工要求的同时能最大限度地提高加工效率,达到了实验最初设计目的。To solve the numerical control system when handling consecutive micro line segment,frequent start-stop,adding velocity mutation to interpolation problem,through the establishment of circular arc transition switching model,according to the constraint conditions that the turning point in planning out the optimal convergence speed,the transition arc based on the new flexible deceleration control algorithm to track speed forward planning.Through experimental verification,the trajectory error output of the lookahead interpolation algorithm does not exceed the maximum value given by the system,and the velocity and acceleration curves are continuous and smooth,which can not only meet the machining requirements but also maximize the machining efficiency.Achieved the original design of the experiment.
