Abstract: A machine tool holding workpieces has measuring probes disposed on spindles. The spindles move in common relative to the workpieces until a termination criterion is reached for the common displacement movement. During the common displacement movement, a position of a measuring probe relative to a respective workpiece is detected where the measuring probe makes contact with the respective workpiece or loses contact with the respective workpiece, allowing geometric statements about the respective workpiece to be derived. The measuring probes are kept at a rest position relative to their respective spindle during the common displacement movement, as long as the respective measuring probe does not yet make contact with the respective workpiece. Following contact with the respective workpiece, a deflection from a rest position is detected. The termination criterion is satisfied as soon as the deflection of at least one of the measuring probes reaches a maximum deflection.
