摘　　要：在不增加关节臂式坐标测量机硬件成本的基础上,为了提高测量精度,讨论了几点关键技术。分析了一个测量模型的不足,提出了一机多模思想;分析了空间误差的不均匀性,探讨了最佳测量区;分析了随机采样的弊端,研究了数据采集技术;分析了标定技术的难点,论述了标定内容。On the base of no increasing in hardware cost, some key technologies are discussed in order to improve articulated arm coordinate measuring machines measurement accuracy. After the deficiency of measurement model is analyzed, the idea of one multi-mode machine is proposed. The inhomogeneity of space error is studied, and the optimal measurement area is presen- ted. The data acquisition technology is presented through the disadvantages of the random sampling. The calibration content is put forward when the difficulties of calibration technology are considered.
