ABSTRACT:
A workholding device comprises a body 10, a plurality of relatively movable base jaws 12, each base jaw 12 carrying one of a plurality of top jaws 13, such that when the base jaws 12 are moved relative to one another, a workpiece 15 can be gripped by the top jaws 13, and a sensing device 14 positioned to sense force transmitted from a top jaw 13 to a base jaw 12. Preferably a second sensing device 16 is provided to sense centrifugal force to permit compensation for its effect on the top jaws, so that a signal can be obtained which is an accurate measure of the force prevailing between the top jaws 13 and the workpiece 15.
