ABSTRACT:
A method and apparatus for dynamically monitoring in real-time the operation of a press machine and tooling during actual production operations, in order to evaluate the true interaction between actual vibration activity occurring at multiple locations within the press machine geometry. A configuration of accelerometers is used to acquire measurement data indicating the acceleration of the press machine and for tooling at a plurality of press machine locations. An integrator converts the acceleration data into displacement data representing the displacement activity of the press machine at the indicated machine locations. Filtering the displacement data provides deflection measurements representing the vibrational activity occurring at the relevant machine and tooling location. Measurements of the relative press motion activity between selected machine locations provide an indication of the influence that deflection activity occurring at respective press machine locations has on one another.
