Abstract
An instrument system for a press machine environment includes a monitoring apparatus to determine the flywheel speed, slide speed, and slide displacement relative to, for example, Top Dead Center. These measurements are used to determine the energy consumed by the slide as a function of slide displacement as its travels during its work stroke. A piston-cylinder combination is disposed at a die location to emulate a die set and to facilitate a determination of the load developed by the slide as it actuates movement of the piston. A computation of the work produced by the slide during piston movement can be determined on the basis of measurements of piston displacement and slide-induced pressure applied to the piston. A display plots various graphs to depict slide energy, slide work, and flywheel speed as a function of slide displacement.
