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.

Method and device for determining actual dimensional properties of a measured object

A computer-assisted method for determining dimensional properties of a measurement object using a coordinate measuring machine. An image representation of the measurement object is shown to a user and the user selects a first geometric element of the measurement object, resulting in the display of eligible test features for the selected first geometric element. The eligible test features are automatically determined from a plurality of typical test features stored in a database, by the selected first geometric element being assigned to one of a plurality of predefined measurement elements stored in the database. A defined measurement sequence is generated in a computer-assisted manner based on the test feature selected by the user. Individual measured values are recorded on the first geometric element using the defined measurement sequence. A numerical value based on the individual measured values is determined, which represents a dimensional property of the first geometric element corresponding to the selected test feature.
