【摘要】 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。更多还原

【Abstract】 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.更多还原
