Abstract:

A new and improved method for calibrating workpiece clamping mechanisms such that once a particular clamping mechanism is calibrated with respect to a particular workpiece to be clamped upon a support surface, the clamping mechanism will always clamp the workpiece with a predetermined, precisely repeatable clamping force. In addition, the method of the present invention may be utilized in conjunction with the calibration of a plurality of clamping mechanisms so as to enable the plurality of clamping mechanisms to always generate the same precise clamping force whereby the multiple clamping mechanisms, utilized to clamp a single workpiece upon a support surface, can in fact clamp different regions of the single workpiece with precisely the same predetermined clamping force such that all regions of the single workpiece are in fact securely clamped.
