ABSTRACT:
A co-ordinate measuring machine has a probe used to touch points on an article under manual control by a user, e.g. from a joystick. A computer determines a vector describing the direction of probe movement prior to touching each point. On the basis of the number of points touched by the user and their respective vectors, the computer makes a decision as to the shape of a feature of the article under inspection, e.g. whether it is a flange, slot, boss, bore, internal sphere, external sphere, cylinder or cone. It can then either calculate a relevant geometrical parameter such as a dimension of the feature, or write a part program for future inspection of the feature on further, nominally identical articles. This can be done automatically without the need for the user to tell the computer anything about the shape of the feature concerned.
