Abstract
A clamp device has first and second jaws movable relative to one another for clamping an object therebetween. A clamp sensor operatively connected to one of the jaws generates a clamping signal representative of a clamping force urging the first and second jaws towards one another. A display is arranged to display a value proportional to the clamping signal which is representative of the clamping force between the first and second jaws. A motor for driving movement of the second jaw relative to the first jaw is operated by a controller that responds to operator commands in a manual control mode and/or which automatically drives the motor so as to maintain the clamping signal measured by the clamp sensor within a prescribed threshold range to apply a constant clamping force between the first and second jaws under an automated control mode.
