Abstract

A method of finding a feature of an object using an analogue probe mounted on a machine tool. The method comprises the analogue probe and/or object following a course of motion which causes the analogue probe s surface sensing region to traverse across the feature to be found a plurality of times whilst approaching the feature over successive traverses so as to ultimately arrive in a position sensing relationship with the feature so as to collect scanned measurement data about the feature along at least part of a traverse.
