Abstract
A force measuring device for simultaneously measuring the static or dynamic force from each jaw of a chuck or segment of a collet. The device is formed with an annular housing having several radially extending openings in which are disposed elongated force transducers. In use, the force transducers are supported at the inner end and project from the housing into engagement with the jaws of a chuck. Each transducer has bridge configured strain gages disposed thereon. The strain gages are connected to appropriate instrumentation through a slip ring arrangement. The unbalance of the bridge circuits is used to indicate the force of the chuck.
