Abstract

A system for monitoring the operation of a press machine employs a sensor to measure the peak acceleration levels of a slide assembly. The sensor measurement data represents peak load levels being developed within the press machine. A data means provides load level capacity data representing the maximum allowable compressive and tensile load levels for the press machine. The capacity data is provided in the form of plural press machine operating zones each representing a corresponding range of load values and having a respective rating factor which indicates the relationship of the particular operating zone to a respective one of the maximum allowable compressive/tensile load levels. A processor evaluates the peak load levels in relation to the operating zone data to determine which respective ones of the plural press machine operating zones encompass each respective one of the peak load levels. The operating condition of the press machine is determined in accordance with the peak operating load levels and the respective rating factors associated with the respective press machine operating zones which are determined by the processor to encompass the peak load levels.
