The test principle of spatial error of CNC machine tools is studied. The testing principle and error model of laser vector measurement are analyzed. Laser doppler displacement meter and laser vector measurement are used to detect and compensate the spatial error of CNC spiral bevel gear machine tool, and assess the spatial properties of the machine tools according to the standard ISO 230-6. The experimental results show that the spatial error detection and compensation technology in the paper is feasible and improve the spatial movement accuracy of CNC machine tools in a certain extent and lays the foundation for the further improvement of the machining accuracy.
