Abstract
A method for the control of a ram movement and ram forces of multi-point servo hybrid presses, where the positions, speeds and forces to drive the ram can be controlled independently of each other by the servo motor, which is assigned to each pressure point or each group of pressure points, for the main drive for the ram movement in the main function and the hydraulic pressure cushions, which are separately assigned to each pressure point of the ram, in an auxiliary function, to influence process-induced position and force settings of the ram in a combinatory interaction to achieve an active control of draw depth and tilt.
