Abstract
A system is provided for monitoring the operation of a press machine over a series of press running cycles. A plurality of press operating events associated with the operation of the press machine are defined. Each press operating event has a modifiable control function associated therewith. An arrangement of accelerometers measures the press machine vibrational activity associated with each press operating event that occurs during the series of press running cycles. A processor processes the vibration measurements associated with the press operating events to identify the presence of a vibration trend therein meeting a defined trending criteria. A controller is responsive to trend identification signals generated by the processor for modifying the respective control function of each press operating event which is associated with identification of the vibration trend.
