Abstract
The invention relates to a method for detecting measurement data on coordinate measuring and digitalizing machines. When the measuring times of the coordinate measuring machine and the sensor are determined by an electric signal (trigger), the equality thereof can be guaranteed and the influence of signal propagation delays can be excluded. The nth sensor information always corresponds to the nth machine information. Allocation is made easier when each value detected at a measuring time obtains an identifier. In one embodiment, surface points of a free forming surface can be detected during movement of the sensor on the coordinate measuring machine and by means of a measuring sensor. The measuring times are determined by an electric signal that is produced by the sensor and is transmitted to the coordinate measuring machine. The signal triggers distance measuring of the sensor as well as the output of the current machine position.
