Abstract Scope The variation of incoming material properties and the quality of emerging high-strength steels significantly increases the costs for product design and production. It is not economical to tightly control material chemistry to eliminate the variation of material properties at steel mills. This paper introduces a methodology on how to implement a nondestructive evaluation (NDE) tool to measure the variation of the incoming material properties. The servo-controlled forming process was optimized to adapt to variations in the incoming material properties in a lab-scale stamping cell. Final stamping quality was obtained with three different batch materials by altering servo press parameters, such as the slide motion and blank holder force, to adjust for the variation of the material properties from one batch to another. A mid-strength (340-MPa tensile strength) steel was evaluated in this study. The effectiveness of both an NDE tool and the servo-press control was evaluated on a 300-Ton mechanical servo press.
