Abstract
Abstract A system employing structural moment detectors for collecting and interpreting data reflecting the effect of at least a selected one of a plurality of forces acting on a structure such as a machine tool. The output signals from the moment detectors are processed to modify the information content (including rejecting components of the signals which reflect extraneous forces other than the selected one). The processed signals are then manipulated to provide secondary signals which are responsive to the condition of the structure as a result of the application of the selected force.

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.
