Abstract
An apparatus for measuring force applied to a blank resting on a tool supported by a tool holder includes a tubular piezoelectric body having a central aperture extending between a first end and a second end of the body, a plurality of legs attached to an outer surface of the body and each having a free end extending beyond the first end of the body, and an elongated tube extending through the central aperture of the body, a first end of the tube terminating between the first end of the body and the free ends of the legs. Indica are provided on an outer surface of the tube for indicating the position of the body in a cavity formed in a tool holder. An electrical cable has a pair of conductors electrically connected to the body for generating a sensor output signal. Potting compound is forced through an interior of the tube to encapsulate the legs, the body, the first end of the tube and the cable to retain the apparatus in the cavity.
