摘要
A method for selecting the proper clamping force to be applied by a rotatable chuck against a workpiece of known rigidity comprises the steps of inserting a transducer of known rigidity into a chuck of known rigidity, measuring the clamping force under conditions of a stand-still and rotation to obtain a change in clamping force induced by rotation, and multiplying the change of force by a correction factor involving the foregoing rigidities to obtain a predicted change of clamping force which would be experienced upon insertion of the workpiece in the chuck. The predicted change in clamping force enables an operator to select a sufficient amount of clamping force for safely retaining a workpiece in the chuck during rotation.
