<p>PROBLEM TO BE SOLVED: To provide a coordinate positioning apparatus for determining whether or not the dimensions of an object conform to tolerance.SOLUTION: The coordinate positioning apparatus employs a measurement probe 6, such as a touch trigger, analogue, or non-contact probe, mounted on a measuring instrument such as a coordinate measuring machine, a machine tool, or a lathe. The coordinate positioning apparatus is configured to drive the measurement probe around a path relative to the object, which is based on tolerance of an object 14. The path relative to the object may include at least one first path based on the maximum tolerance of the object and a second path based on the minimum tolerance of the object. Further, the coordinate positioning apparatus is configured to monitor all of the probe measurement data acquired by the measurement probe while the measurement probe is driven around the path and to indicate that the dimensions of the object do not conform to tolerance only in the case of variation in the state of the probe measurement data which is acquired while the measurement probe is driven around the path.</p> |
