Paper Abstract

Laser tracker as a three-dimensional measuring instrument for large dimensions is widely used in the industrial measuring system, which is famous for its high precision, high efficiency, in site measurement and easy to be moved or installed, etc. In order to measure the large annular planes, especially non-continuous planes, a method with laser tracker on the basis of station-moving measurement is proposed. In this paper, the working principle of laser tracker system is described firstly, then the principle of the station-moving measurement is analyzed, finally according to the station-moving measurement principle experiment of the flatness measurement of a Φ5000mm round table is carried out, the result is compared with bridge-level, and feasibility of measuring flatness of large precision parts is validated by experiments and analysis results.
