Abstract
A feedback control system for use in a press machine is adapted to monitor and adjust the clearance between the gib and slide. A pressurized chamber, such as a hydraulic piston-cylinder combination is disposed in actuating relationship to the gib. Selective pressurization of the piston-cylinder induces a controlled displacement of the gib towards or away from the slide, thereby regulating the spatial relationship therebetween. A sensor provides a measure of any possible clearance between the gib and slide. The clearance measurement is compared to allowable reference data. A controller controls the pressurization of the chamber in accordance with the comparison results, thereby controllably moving the gib. The gib may be selectively displaced to optionally effectuate a minimal clearance condition.
