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

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.

Adapter element for assembling a rotational apparatus in the measurement space of a coordinate measuring machine

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. The method comprises the steps of: a) initially determining the parameter, and setting the initially determined parameter as target value; b) moving the object from one position to a next position, and re-determining the parameter for a movement cycle between the corresponding positions; c) setting the re-determined parameter as an actual value; d) comparing the target value with the actual value; e) continuing the movement of the object if the comparison results in that the actual value substantially coincides with the target value, and returning to the step b) as long as a last position has not been reached; or f) outputting an error message if the comparison results in that the actual value deviates significantly from the target value.
