Abstract
The invention is directed to an articulating device for a probe head ( ) of a coordinate measuring apparatus with the articulating device having at least two rotation joints ( ) for angularly aligning the probe head ( ). In this articulating device, corrective values are assigned to the device with which the errors caused by the elastic deformation of the articulating device are corrected when making measurements. To improve the measuring results, a mathematical model is used for correcting the deformation and this mathematical model includes at least one mathematical finite element ( ).
