英文摘要：

The Revo probe was used for the first time in coordinate measuring machine system to solve the problem of low accuracy for articulated ann coordinate measuring machine. The geometrical relationship was found between rota- tional joints and measuring bar through analysis of the structural features of system, and the approach vector was calculated according to this relationship. So the control of measuring bar＇s posture was realized. An algorithm of self- adaptation measuring was proposed based on measuring pole＇s initial posture. The minimum variation of posture was obtained on the basis of known coordinates of data. The calculation of inverse position was completed by the posi- tional equation. The experiment shows that the control of Revo probe＇s posture and inverse position are achievable through applying this algorithm. The theory foundation is built for the further research on the development and kine- matics of the articulated arm coordinate measuring system with high freedom and Revo probe.
