| Abstract: | 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. |
