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.
