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.
