Abstract: A die tool wear monitor and analysis system identifies tooling wear, variations in the quality of the manufactured product, and undesired operational conditions within a press. A first signal indicates the angular position of a reciprocating ram and a second signal indicates the force differential present between the tooling components. The second signal is plotted relative to the first signal and defines a value of force differential for selected positions of the upper and lower tooling relative to each other. Preferred values consisting of at least one upper and one lower limit are established for each of the second signals with respect to each of the first signals. The second signal is compared to the established preferred values and when it falls beyond them, the manufacture part is ejected and/or the operation of the conversion press is terminated.
