摘　　要：提出了一种光滑进给速度整数优化模型,实现了多工具联动控制,确保了加工系统中高速数控机床的平稳运转。该模型将加工段的车削因子转化为相应的联动进给速度,并考虑了轴向进给速度和进给加速度的限制。阐述了工具联动控制轨迹规划方法中轨迹限制条件的定义,然后根据定义的限制条件值给出了所有可能的加速度轨迹形状,并给出了各种轨迹形状下的完整算法及实现,简化了模型的决策变量和约束条件。在此基础上,详细讨论了基于简化模型最优解的平滑运动速度优化方法。仿真和实验结果表明,该方法可以实现机电一体化加工系统多工具联动控制。In this paper,an integer optimization model of smooth feed speed is proposed,which realizes Multi Tool linkage control and ensures the smooth operation of high-speed CNC machine tools in the machining system.The model converts the turning factor of the machining section into the corresponding linkage feed speed,and considers the constraints of axial feed speed and feed acceleration.This paper describes the definition of trajectory constraint conditions in the tool linkage control trajectory planning method,and then gives all possible acceleration trajectory shapes according to the defined constraint conditions,and gives the complete algorithm and implementation of various trajectory shapes,which simplifies the decision variables and constraint conditions of the model.On this basis,the optimal method of smooth motion velocity optimization based on the simplified model is discussed in detail.The simulation and experimental results show that this method can realize multi-tool linkage control of mechatronics machining system.
