ABSTRACT:
A method of monitoring the forces applied to dies in an underdrive press includes the step of determining the position of a frame in an upper slide of the press in relation to a surface of the slide. One or more force sensing transducers are then mounted on the surface of the upper slide each in a predetermined position with respect to the frame of the slide. The transducers are connected to a load monitoring device which is then calibrated to indicate the forces being applied to dies in the press during the operation of the press. The same steps are performed for each slide of an underdrive press having an inner upper slide and an outer upper slide.
