ABSTRACT:
Method of and system for monitoring the operation of a stamping press including a punch and a die for forming parts from a blank based on processed punch tonnages measurements at predetermined locations in the working stroke. The method includes selecting at least two punch locations at which a press variable measurement will be made and operating the stamping press so as to produce production parts to measure a production press operating variable at the locations for each production part produced. The method also includes processing the production press operating variables to obtain production operating parameters and comparing the production operating parameters to predetermined operating limits representing limits within which the variation in blank thickness and work hardening coefficient of the sheet metal are in control and acceptable stampings are being produced.
