Abstract / Hauptanspruch
|A CMM has a measuring head for recording measurement values associated with an object having a plurality of geometric elements. Defined geometric elements are selected from the plurality of geometric elements and test features relating to the defined geometric elements are determined depending on demand data provided for the geometric elements. Initially, a first measurement sequence including first control commands for controlling the measuring head are determined depending on the test features. The first measurement sequence is modified before the individual measurement values are recorded in order to obtain a second measurement sequence with second control commands, which differ from the first control commands. The second control commands are used for controlling the measuring head and are selected so that the measurement results at the selected geometric elements each have a defined measurement uncertainty that is smaller, by a defined absolute value, than acceptable manufacturing tolerances for the geometric elements.|
