Abstract

The binder force in sheet metal forming controls the material flow into the die cavity. Maintaining precise material flow characteristics is crucial for producing a high-quality stamped part. Process control can be used to adjust the binder force based on tracking of a reference punch force trajectory to improve part quality and consistency. The purpose of this chapter is to present a systematic approach to the design and implementation of a suitable MIMO process controller. An appropriate process model structure for the purpose of controller design for the sheet metal forming process is presented and parameter estimation for this model is accomplished using system identification methods. This paper is based upon original experiments performed with a new variable blank holder force (or variable binder force) system that includes 12 hydraulic actuators to control the binder force. Experimental results from a complex-geometry part show that the MIMO process controller, designed through simulation is effective.
