LINEAR AND ANGLE DISPLACEMENT MEASUREMENT OF VERTICAL MILLING CENTER USING A MULTI-AXIS CALIBRATOR

The paper presents the methodology results of measurements of the accuracy of movements of the linear axis of a CNC machine. The XM-60 multi-axis calibrator by RENISHAW was used as a research apparatus. It allows measurement in six degrees of freedom in any spatial orientation with one mounting. This translates into an increase in the accuracy of measurements performed due to the elimination of the need to adapt the test bench depending on the measurements performed. This made it possible to measure linear and angular displacements from one mounting of the test apparatus. Due to the repeatability of the measurement method for each of the CNC machine axes, the article presents the measurement and results of the Y axis of the DMU50 vertical milling center.
