The paper presents motion control algorithms and dynamics error of inspection for a five-axis machining tool, to improve the accuracy of TCP (Tool Center Point) of multi-axis motion. Firstly, inverse kinematics equations and servo dynamic models of the five-axis machine are derived, and the dynamics models are verified by means of system identification. Therefore, tracking errors and multi-axis contour errors are reduced through tuning five-axis servo control loops and servo gains, respectively. The proposed methods can be implemented on a PC-based controller and performed on the five-axis engraving machining. Finally, experiment and simulation results demonstrate that the feasibility of five-axis TCP interpolation and motion control algorithms and the dynamics contouring error can be significantly improved on dynamic inspection of a five-axis machine tool.
