Paper Abstract

The shafting error has a great influence on the measurement accuracy of the laser tracker. Based on the error expression form, a mathematical model is established for the eccentricity error of the shafting system, and the simulation analysis is carried out. The tilting error of the shafting system is obtained from the angle of the geometric angle and the moiré fringe respectively. A specific analysis was carried out. A laser tracker angle measuring system was built to analyze the shafting error in the system and correct the shafting error. The experimental results show that the original error of the laser tracker angle measurement is 189.31", and the corrected angle error is 127.13", which provides a theoretical basis for the highprecision measurement of the laser tracker.
