摘　　要：针对数控机床加工微小线段时因加加速度突变而导致精度和效率下降等问题,提出一种新型柔性加减速控制算法。该算法基于正弦函数构建了加加速度连续平滑的运动控制曲线,并通过分析数控机床加工线段的长度和初末速度,实现新型柔性加减速算法的速度规划。仿真与实验测试结果表明:与传统S形算法相比,该算法能有效地降低因加加速度突变引起的振动,提高数控加工过程中的平稳性与效率。A new flexible acceleration and deceleration control algorithm was proposed to solve the problem of precision and efficiency degradation caused by sudden jerk change in the process of machining micro-segment by CNC.The continuous and smooth motion control curve of jerk was built based on the sine function,and the speed planning of the new flexible acceleration and deceleration algorithm was realized by analyzing the length of the processing line segment of the CNC and the initial and final speed.The simulation and experimental test results show that this algorithm can effectively reduce the vibration caused by the sudden change of jerk and improve the stability and efficiency of NC machining process compared with the traditional S-shaped algorithm.
