ABSTRACT:
Method and system for monitoring the operation of a machine having a traversing tool or die member, based on a plurality of features extracted from a process signature. The method includes defining the plurality of features, each feature representing a parameter associated with the process of forming the parts, and operating the machine so as to produce a predetermined number of production parts while collecting a production operating signature. The method also includes extracting the feature values from the production operating signature to obtain production feature values, and comparing the production feature values to predetermined operating limits which represent limits within which acceptable parts are formed.
