摘　要:通過對三坐標測量機更換測量系統，改進、設計與此相配的機械部分，從而建立誤差補償模型，并進行誤差測試，同時利用軟件進行誤差補償。結果證明：本誤差補償方法能使測量機的空間精度提高2—3倍，且這種補償方法簡單可靠，為通過誤差補償提高三坐標測量機的精度提供了簡單而有效的手段。[著者文摘]

Error Compensation to Three Coordinate Measuring MachineZHAO Tianehan , WU Hui , FENG Jun , WU Wenbing 1. Eleetromeehanieal School, Jianghan University, Wuhan 430056, China; 2. Beijing Nanhanglike Mechanic Co, Ltd, Beijing 100076, ChinaAbstract:Some modification to the three coordinate measuring machinec （CMM）, was accomplished with changing the measuring system and modifying the corresponding mechanical parts. A better error compensation model was constructed which applied software to measure the error. As a result, it increases the volumetric accuracy by 2 or 3 times. The method is convenient and reliable to improve the accuracy of the CMM through the error compensation.[著者文摘]
