Abstract
Official abstract text for this publication.
The present invention provides a method for operating a press which includes providing a press with at least one plunger which executed a stroke, an upper tool part, a sub-structure. A control and regulation device receives a value(s) on an operating condition from a system of the press. The value(s) are provided from the system of the press to the control and regulation device during a processing of a work piece. The value(s) provided are processed to the control and regulation device according to a function F ( x ) = L x · F 2 under the condition that L > x > L 2 so as to permanently operate a movement of the plunger via a drive device and the press in a controlled manner or in a regulated manner according to a system of forces required for a work piece with a respective force which is actively influenced or is actively modified in a position and a dimension/amount.
