Coordinate measurements are the source of digital data in the form of coordinates of the measurement points of a discrete distribution on the measured surface. The geometric deviations of free-form surfaces are determined (at each point) as normal deviations of these points from the nominal surface (the CAD model). Different sources of errors in the manufacturing process result in deviations of different character, deterministic and random. The contribution of random phenomena on the surface depends on the type of processing. The article suggests an innovation in applying the methods of analysis of spatial data in research on the geometric deviations randomness of free-form surfaces, consisting in testing their spatial autocorrelation. In the research on spatial autocorrelation of free-form surface deviations, Moran's I statistic was applied.
