The four components of the deviations of a rotary table from an ideal axis of rotation can be obtained by a single measuring method wherein a test body (4) having a plurality of well-defined measurement points is placed on the rotary table (1) and the positions of said measuring points are then determined by means of a coordinate-measuring instrument (3), for each of various angular positions of the rotary table, there being thus a set of ascertained measurement-point coordinates for each of the angular positions of the rotary table. From the sets of measurement-point coordinates, the travel deviations f.sub.a, f.sub.r and f.sub.t of the axis of rotation, and the angle-position deviation p.sub.w are then determined by calculation.
