Title: WORKPIECE MEASUREMENT METHOD
Abstract:
Disclosed is a method for measuring a workpiece (W) on a machine tool (100) in which a probe (114) and the workpiece are moved relative to each other by a plurality of feed shafts and the position of the workpiece is obtained on the basis of the coordinates of the feed shafts when the probe and the workpiece come into contact with each other. In this method, one of the plurality of feed shafts is moved to a desired measurement position, the coordinate values of the one feed shaft are recorded when the feed shaft is at the desired measurement position, the probe and the workpiece are moved relative to each other by the one feed shaft and another feed shaft, the movement by the one feed shaft is stopped when the recorded coordinate values have been reached, and the probe is moved using the other feed shaft and the workpiece is measured at a plurality of measurement points while the one feed shaft is stopped at the aforementioned coordinate values.
