摘要: A rotatable chuck for securing a workpiece in a machine includes a base element having a center and a plurality of jaw elements movable relative to the center. The jaw elements are movable to clamp the workpiece. The jaw elements exert a measurable clamping force on the workpiece. The clamping force exerted on the workpiece is measured and the jaw elements are moved relative to the center to vary the clamping force exerted on the workpiece. A comparator compares the measured clamping force to a predetermined clamping force and the jaw elements are moved, as the chuck is rotating, to adjust the clamping force on the workpiece relative to the predetermined clamping force.
