The Research of Positioning Error Measurement Based on Reinshaw Laser Interferometer XL-80
Abstract
In order to improve the positioning accuracy of CNC machine tools and ensure the size and accuracy requirements of maching parts of CNC machine tools. The THWLBTF-3 machining center is used as the test platform and the Reinshaw laser Interferometer XL-80 is adopted in this paper. The positioning error of X-axis of machining center is measured through non-contact and online measurement, and the test data is measured by software. The results show that the magnitude of pitch error of machining center is one of the important factors affecting the positioning accuracy of machining center.
