Beschreibung
Zusammenfassung:	A machine tool for machining pre-toothed workpieces has a workpiece carrier, a workpiece spindle with a workpiece spindle housing and a workpiece spindle shaft. The machine tool has a meshing sensor, a calibration piece, and a sensor controller which is designed to perform the following procedure: Moving the meshing sensor relative to the workpiece spindle into a calibration position in which the meshing sensor is located at the calibration piece 10; determining a response behavior of the meshing sensor by the sensor controller moving the meshing sensor relative to the calibration piece and meanwhile receiving sensor calibration signals of the meshing sensor, and moving the meshing sensor into a workpiece measuring position in which the meshing sensor is located at the workpiece, the workpiece measuring position depending on the determined response behavior.
