ABSTRACT:
An edge finding or indexing probe for locating an edge surface of an article positioned adjacent thereto. The edge finding device includes a housing having a first cylindrical cavity therein defined by a first cavity axis coaxially therethrough and a first cavity radius. A locating element includes a first cylinder defining a first circumferential surface for communicating within the first cylinder cavity of the housing. The locating element further includes a second cylinder defining a second circumferential surface for communicating with the edge surface of the article positioned adjacent thereto. The algebraic sum of the radius of the first cylinder plus the radius of the second cylinder is equal to the radius of the first cavity, whereby the localizing element moves within the first cavity to locate the edge surface along an extension of the first cavity axis.
