Abstract
Stamping process control is achieved by commanding actuation mechanisms to appropriately vary material flow into the die during the stamping cycle, based on feedback on part quality. The actuation mechanisms in turn employ closed-loop control to achieve the desired material flow. Thus, process control forms an outer loop while control of the actuators form an inner loop. The inner-loop control is referred to as machine control and in this chapter, the nonlinear dynamics of hydraulic actuators for variable binder-force control are analyzed and machine control approaches for these actuators are described. Real-time digital implementation of machine control algorithms is also considered.
