  • To identify the geometric errors of three-axis vertical CNC machine tools, the circular motion trajectories of three-axis vertical machine tools were modeled by using the theory of multi-body system. Based on the numerical simulations of circular motion trajectories, the influence mechanism of the typical geometric errors on the circular motion trajectories was analyzed. Considering the influence of multiple geometric errors on the circular motion trajectory, this paper put forward a geometric errors identification method, which can identify all 21 geometric errors of three-axis vertical machine tools based on the least squares method and polynomial based error modeling. Numerical simulation results demonstrate the accuracy and feasibility of this method.
