ABSTRACT:
A method wherein the position of a workpiece of an NC-controlled machine is determined, and an apparatus which includes at least one center point and a computing unit. The position of the center point is ascertained by a measuring device and the measured value is fed as a signal into the computing unit. Using the computing unit and the measurement signal, the position of the center point and, thus of the workpiece can be determined. The measuring device is associated with a tailstock of the apparatus and is connected to the computing unit. The measuring device is integrated in the apparatus, so that no additional measuring unit is required. It is also not necessary to provide an installation area for such a measuring unit in the region of the workpiece.
