A method is described for determining a relative position of an axis of rotation of a rotary table of a coordinate measuring machine. The rotary table has or forms a reference element that is arranged eccentrically in relation to the axis of rotation. The method includes a measuring step including performing a rotary movement of the rotary table, and producing measuring points that encode a position of the reference element by a sensor of the coordinate measuring machine during the rotary movement. The method includes a determining step including determining the relative position of the axis of rotation of the rotary table based on the measuring points.

Method and apparatus for determining a relative position of an axis of rotation of a rotary table for a coordinate measuring machine

A coordinate measuring machine for determining dimensional and/or geometric properties of a measurement object has a measurement element, which defines a reference point and is movable along multiple movement axes relative to a measurement object receptacle. The movement axes include multiple linear axes and at least one axis of rotation. In order to control the measurement element relative to a measurement object, desired positions of the reference point and parameters defining limit values for permissible velocities and/or accelerations are provided. Multiple individual temporal sequences of respective individual axial positions for the plurality of movement axes are determined as a function of the desired positions of the reference point and the parameters. The individual temporal sequences each have individual time intervals between successive individual axial positions. The individual temporal sequences are synchronized onto a common timing cycle, which uses the longest individual time interval in each case for each target position.
