| Abstract: | The fabrication of an articulated coordinate measuring machine (ACMM) which has 6 degree of freedom (DOF) was presented. The measurement formulation and its error model were analyzed by means of the Denevit-Hartenberg (D-H) method. With a laser tracker, the parameter calibration model was analyzed by means of space coordinate translation theory. A comparison of measurement precision before and after the parameter calibration was given. The results show that the high precision laser tracker can be used for the calibration of ACMM. |
