Abstract
A method for compensating a measurement error related to a measurement of a desired measuring point at an object to be measured with a coordinate measuring machine is disclosed. Some embodiments include a touch probe. Some embodiments include a method that includes providing a three dimensional reference body of known shape and dimension at a known position in the measuring volume of the coordinate measuring machine, defining multiple reference points to be measured at the reference body, touching the reference body with the touch probe in defined touching directions according to the multiple reference points and thereby determining positions for the multiple reference points, and deriving a lobing error information for the touch probe based on the known shape and dimensions of the reference body and the determined positions of the reference points, the lobing error information providing error values related to respective touching directions for the touch probe.
