A method of using the apparatus for calibrating an air gap sensor can include attaching the apparatus to a machine tool using only magnetic force to keep the apparatus in place.

Embodiments of the disclosure discloses a calibration bracket. The calibration bracket includes a base, a vertical rod, a transverse force application member and a transverse force application mating member. The vertical rod is detachably mounted to the base. The transverse force application member is disposed on one of the base and the vertical rod. The transverse force application mating member is disposed on the other of the base and the vertical rod and is configured to be connected to the transverse force application member to apply, to the vertical rod, a force parallel to the base. A limiting protrusion is provided on one of the base and the vertical rod. A limiting opening is provided on the other of the base and the vertical rod. The limiting opening can allow the limiting protrusion to pass through the limiting opening and snugly abut against the limiting protrusion when the transverse force application member applies a transverse force to the vertical rod. By means of the structure described above, the vertical rod can be quickly mounted to or detached from the base. Therefore, the calibration bracket is easy to assemble and transport.

A measurement system using heat compensation profiles for compensating inaccuracies caused by heat distortion is disclosed. Measurement of objects with different heat distribution involves use of heat compensation profiles with corresponding heat distribution. The heat compensation profile comprises a set of compensation coefficients that represent the deviation of the object having a heat distribution according to the heat compensation profile and the cooled down object. When the compensation coefficients are applied to the measured object the resulting measures correspond with the measurement results of the object after the object has been cooled.

The present application discloses a method for calibrating a measuring probe in a gear cutting machine by using a workpiece received in a workpiece holder of the gear cutting machine, wherein the measuring probe includes a measuring probe tip which is movably arranged on a measuring probe base, wherein the deflection of the measuring probe tip relative the measuring probe base can be determined via at least one sensor of the measuring probe, and wherein the measuring probe is traversable relative to the workpiece holder via at least two axes of movement of the gear cutting machine. The method comprises rotating the workpiece via an axis of rotation of the workpiece holder and traversing the measuring probe via the at least two axes of movement of the gear cutting machine such that in the case of a perfect calibration the touch point of the measuring probe tip on the tooth flank would remain unchanged.
