Abstract
Some embodiments of the invention include a calibration method for a coordinate measuring machine. In some embodiments, the method may include emitting and directing the laser beam towards a first of the set of retro-reflectors, whereby a measuring path is defined by the orientation of the laser beam, moving the calibration laser head along the measuring path so that the laser beam is kept directed towards the first retro-reflector according to the measuring path and the reflected laser beam is continuously received at the calibration laser head, measuring the change in distance to the first retro-reflector at a plurality of measuring positions along the measuring path and gathering a machine position for each of the plurality of measuring positions, the machine position relating to a position of the tool carrier relative to the base.
