| Abstract: | A separated calibration method of coordinate measuring machine with two parallel rotational axes based onthe reversal method was presented in this paper, aiming at the calibration problems of articulated arm coordinatemeasuring machine （AACMM）. The reversal method of calibration is explained, and the use of reversal method forparallelism error calibration, arm length error calibration and zero error calibration are described. This method is easyto operate, and its measurement uncertainty can be obtained by measuring gauge blocks within its measurementrange. The experiment proves that the measurement uncertainty of the machine using the separated calibration methodbased on the reversal method is three times higher than that using the integrated calibration method based on theGauss-Newton method |
