Abstract
A gauge for determining the diameter of an eccentric cylindrical workpiece part during grinding. The measurement is effected by a pair of fingers adapted to engage diametrically opposite regions of the part. The fingers are carried at the ends of a pair of elongate probes mounted on the grinding wheel table so as to move therewith, thereby to follow the eccentric movement of the said part in a horizontal plane, as the workpiece rotates. The probes are slidable in a generally vertical sense relative to the grinding wheel table and relative to each other. The two probes are also slidable as a unitary assembly relative to the table, in a direction towards the workpiece, with the two fingers positioned above and below the upper and lower extremities of the eccentric movement of the workpiece part, to allow subsequent gauging thereof by closure of the two fingers onto the part to make contact therewith. After grinding to size, the probes are movable to disengage the fingers from the workpiece part, and also movable away therefrom to permit relocation or removal of the workpiece. One of the probes may be slidably supported on the other probe.
