During linear displacement measurement of CNC machine tools (MT) with laser interferometer the optical components are moved along the measured axis. At the selected measurement points of the axis the optics stops and data collection is performed. At the beginning of the stopping cycle, because of the inertion of the optics and the MT structure, vibrations occure, which spoils the collected data. To minimize the dwell time, the time needed to wait at the measurement point, the number of the collected position data needs to be minimized. In this work through an example is represented the influence of the number of collected data on the measurement values during linear displacement measurements of machine tools.
