Paper Abstract

Researched on the probe’s diameter error of the Articulated Arm Coordinate Measuring Machine (AACMM) in the measuring process. Based on the analysis of the influence of the error source on the accuracy of the probe, the influence of the contact force on the measuring diameter of the probe was analyzed emphatically. It was proposed to use the Coordinate Measuring Machine (CMM) to identify the probe diameter error of the AACMM and apply the least square method to compensate the probe diameter error. The results show that the research method has certain feasibility. The maximum error of the length measurement is reduced by about 47 um. The average error is reduced from 0.0315 mm to 0.0046 mm, which improved the measurement accuracy of the AACMM.
