Title: Machine health monitoring system

Having described our invention in such clear and concise terms to enable those skilled in the art to understand and practice it, we claim:

1. A system for collecting and interpreting data reflecting the effect of at least a selected one of a plurality of forces acting on a machine tool for forming and/or bending metals, said system comprising, in combination:

(a) at least one structural moment detector carried by said machine tool assembly for generating output signals in response to said plurality of forces acting on said machine tool assembly;

(b) means for processing said output signals to modify the information content thereof, including rejecting components of said signals which reflect the effects of extraneous forces other than said selected one; and

(c) means for manipulating said processed signals to provide secondary signals responsive to the condition of said machine tool assembly as a result of the application of said selected force.
