Abstract: 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.

Abstract: An arrangement includes a rotary apparatus, a device, and an adapter element configured to assemble the rotary apparatus in a measurement space of a coordinate measuring machine. The rotary apparatus has an axis of rotation (D). The adapter element includes a first fastening portion configured to fasten the adapter element in the measurement space, a second fastening portion, and a coupling portion. The rotary apparatus is fastened to the adapter element at the second fastening portion. The device is coupled to the adapter element at the coupling portion. The coupling portion is arranged adjacently to the second fastening portion. The device is positioned on the adapter element next to the rotary apparatus.

Abstract: A system and a method for reliably monitoring a parameter, in particular a moment of inertia, required for determining a kinetic energy of an object that can be measured by means of a sensor of a coordinate measuring machine. The object is moved between various positions, with the object preferably being at least briefly at rest in each of the approach positions.

Abstract: A measuring arrangement is calibrated for determining rotational positions of a rotary device that has a first part and a second part which can be rotated relative to the first part about a rotational axis. Rotational positions of the first part relative to the second part and/or rotational positions of the second part relative to the first part are detected using a plurality of sensors distributed about the rotational axis. A respective measurement signal corresponding to each detected rotational position is generated such that redundant information on the rotational positions of the first part and the second part relative to each other is provided. The redundant information on the rotational position(s) are analyzed such that effects of a translational movement of the first and the second part relative to each other are corrected, the translational movement running transverse to the extension of the rotational axis.
