Apparatus and method for determining the location of peripheral points of bodies

Abstract

An apparatus and method for determining the geometrical position of peripheral points of bodies, especially of bodies of rotation, is disclosed. The points are measured relative to an axis of the bodies by a sensing gauge head. The head is preferably carried on an upper carriage of two carriages that move at right angles with respect to one another. The sensing gauge head carries a stretched wire which serves as a measuring face. When the measuring wire makes contact with the body to be measured, an electric circuit is closed to trigger an optical signal. Acoustic and/or motor controlling signals may also be triggered by the contact with the body. A contact brush may also be provided on the sensing gauge head to warn the operator that contact with the measuring wire is imminent.
