| Abstract: |
| According to the detection of the positioning accuracy of CNC, the measuring principle and the measurement methods of laser interferometer are analyzed. In order to reduce the errors of positioning accuracy and repeat positioning accuracy, interval segmentation compensation is advanced to compensate the errors. Error compensation experiments are carried out to validate the method. The results show that the principle of method is correct and the method has good results. |
