Currently, emphasis is placed on the ever-higher accuracy and speed of measuring the geometric accuracy of CNC machine tools. Achieving the highest possible accuracy is often time-consuming, which results in higher financial costs. The purpose of this study was to verify the suitability of the dynamic measurement of the position CNC machine based on laser interferometry using angular optics concerning static measurement. In the case of both measurements, a commercially available laser interferometer XL-80 was used. First, a static measurement was performed on the horizontal X axis, then a set of dynamic measurements was performed, and the last static measurement was evaluated as a control. The test therefore assesses the accuracy of dynamic position measurement in accordance with ISO 230-2 parameters. The advantage of dynamic measurement is the provision of a more realistic and detailed view of CNC machine tool errors thanks to the high resolution of the measurement itself. At the same time, this research opens another unexplored area of mutual synchronization of data obtained from the CNC machine and data from the reference method.
