  • Patent number: 11027391
    Abstract: Disclosed is a workpiece measurement method for determining the position of a workpiece on a machine tool based on feed shaft coordinates when a probe and the workpiece contact each other, in which the probe and the workpiece are moved relative to each other. The method includes the steps of moving one of the plurality of feed shafts to a desired measurement position, storing coordinate values of the one feed shaft at the desired measurement position, moving the probe and the workpiece relative to each other by means of the one feed shaft and another feed shaft, stopping the movement by the one feed shaft when the stored coordinate values have been reached, and measuring the workpiece at a plurality of measurement points by moving the probe using the other feed shaft in a state in which the one feed shaft is stopped at the coordinate values.
