摘　　要：分析五轴联动机床的误差项和拓扑结构,给出伺服轴运动时理想情况和有误差情况下的坐标变换矩阵。以此为基础,给出五轴联动机床空间综合误差的计算方法。基于多体运动学的微分变换原理,给出五轴联动机床综合误差解耦算法。以某RTTTR型五轴联动机床为例,应用MATLAB进行实际综合误差解耦和补偿计算,结果验证了该解耦算法的正确性。The error items and topological structure of the 5-axis machine tool were analyzed, and the coordinate transformation matrix with and without errors when the servo axis moving were given. On this basis, the volumetric comprehensive error calculation method for the 5-axis machine tool was given. The volumetric comprehensive error decoupling algorithm for 5-axis machine tool was given based on the differential transform principle of multi-body kinematics. Taking the RTTTR type 5-axis machine tool as an example, the actual comprehensive error decoupling and compensation were calculated by using MATLAB. The results show that the decoupling algorithm is correct.
