ABSTRACT:
A digital computer-based degree of freedom (DOF) control system for driving a moving ram of a hydraulic press about a plurality of degrees of freedom as a function of a preestablished motion control program. Actuators responsive to actuator commands drive the moving ram at a plurality of spaced locations. Digital feedback data representative of the positions and loads of the moving ram at the spaced locations are stored in memory. Motion control data representative of the motion control program is also stored in memory. A digital control computer implementing servoloop operations generates the actuator commands as a function of the feedback data and motion control data.
