Purpose. To increase the accuracy of determination of the parameters of movement trajectories of the spindle on hydrostatic bearings, based on the use of high-precision laser triangulation position sensors and digital signal processing. Methodology. For the experimental research of regularities of the spindle block accuracy formation in terms of the accuracy trajectories movement of the spindle, the method of trajectories with modern, high-precision means of measurement and digital information processing has been used. The parameters of the spindle movement trajectories were estimated by statistical descriptions of magnitude the radius vector. The frequency content of trajectories of the spindle was analyzed by the method of spectral analysis. Findings. Based on the application of modern highprecision measuring tools and digital signal processing, we have developed the information-measuring complex for the research on trajectories of the spindle. The methodology of experimental research on movement trajectories of the spindle with hydrostatic supports has been proposed. The methodology allows us to determine statistical descriptions of the accuracy of the spindle block with high accuracy under the simultaneous impact of technological loads, pressure and oil temperature in hydrostatic supports. The application of the proposed methodology allowed us to establish the clear stochastic character of movement trajectories of the spindle with hydrostatic supports, especially under relatively small harmonic load. The results of the analysis of indicators accuracy of spindle rotation, depending on the operating parameters of the hydrostatic supports are presented. Originality. Statistical descriptions of the spindle trajectories and their influence on the formation of the spindle block accuracy indicators depending on the operational parameters of hydrostatic supports and technological loads were established. Practical value. The proposed methodology of the research on the accuracy of the spindle movement trajectories based on the modern precision information-measuring complex can be used to analyze the accuracy of a wide range of rotating units of technological equipment.
