Abstract

The invention is directed to a method for making coordinate measurements on a workpiece on a machine tool. In this method, the workpiece 25 remains on the machine tool during the measuring operation and is scanned via a measuring arm of a coordinate measuring apparatus 31 set up next to the machine tool 21. The coordinate measuring apparatus 31 has its own measuring system for detecting the movements of the measurement arm 34 or of the probe 35 attached to the measuring arm. It is not absolutely necessary that the coordinate measuring apparatus 21 have its own drives or that it has its own CNC-control because the measurement arm or the probe head can be guided or moved with the aid of an entrainment device 27 by the drives of the machine tool 21.
