VIBRATION SEVERITY MONITOR TO CONTROL PRESS OPERATING SHUTHEIGHT AND PROCESS OPERATING CONDITIONS
First Claim
1. A method for use in association with a press machine to adjust the press machine shutheight, said method comprising the steps of:
- providing a reference signal;
running the press machine in an operation;
providing a performance indicia signal indicative of a performance aspect of the press machine operation;
comparing the performance indicia signal to the reference signal and generating a comparison signal representative thereof; and
controlling the press shutheight using the comparison signal

Abstract
A system monitors vibration activity in a press machine environment and generates a signal indicative of vibration level severity. An accelerometer can provide measured peak acceleration data that serves as an indication of vibration level. The vibration measurement, is compared to a reference vibration level that corresponds to a run condition of desired operating parameters. A controller controls the press machine shutheight in accordance with the differential expressed in the comparison result. The consequent shutheight adjustment effects a change in the vibration activity that acts as a correction to the deviation in vibration behavior expressed by the differential.
