ABSTRACT:
A method of detecting the forming of defective parts with a progressive die includes the step of generating a reference force/displacement curve for each forming station of the die while a number of sample parts are formed. The curves are stored in a data processor. The forming force at each forming station, and the displacement are monitored during the formation of production parts and supplied to the data processor. The production force data are compared to the reference force data for each displacement to indicate faults in various parameters previously set into the data processor.
