Abstract:
1. A method for monitoring operation of a press assembly including a press having a replaceable die attached thereto, the die being configured to form a workpiece, the press including a plurality of press elements, including a movable portion for moving a portion of the die, a mechanical power source, and a plurality of power transmission elements for transmitting mechanical power from the mechanical power source to the movable portion of the press, the method including: establishing a baseline vibration level for a first location on the press assembly, the baseline vibration level defining a boundary for vibrations beyond which one or more of the press elements have a reduced life expectancy; measuring vibrations at the first location on the press assembly during operation of the press; measuring vibrations at a second location on the press assembly during operation of the press; and correlating the measured vibrations at the first location with the measured vibrations at the second location to establish a relationship between the vibrations at the first and second locations.
