基于多体系统运动学理论，分析了多轴机床的拓扑结构关系及各个运动轴的误差项元素，建立了多轴机床运动空间的几何误差模型。基于Labview开发了误差补偿平台，进行了误差补偿试验。通过对比补偿前后各轴线性定位误差和补偿前后的数控加工代码，验证了所建立的误差模型的正确性，且该补偿方法是可行的。
基于多體繫統運動學理論，分析瞭多軸機床的拓撲結構關繫及各箇運動軸的誤差項元素，建立瞭多軸機床運動空間的幾何誤差模型。基于Labview開髮瞭誤差補償平檯，進行瞭誤差補償試驗。通過對比補償前後各軸線性定位誤差和補償前後的數控加工代碼，驗證瞭所建立的誤差模型的正確性，且該補償方法是可行的。

Based on the theory of multi?body system kinematics, the topology structure relationship of the multi?body machine tools and axis error term elements of each motion axis were analyzed. The geometric error model of multi?axis machine tool movement space was established. Error compensation platform was developed based on the Labview, and the error compensation experiment was carried out. By compared each axis positioning error and numerical control ( NC) machining code before and after the compensation, the established error model is verified correct, and the compensation method is feasible.
