Abstract
A method is described for operating an electric press which comprises an electrically actuated press ram, at least one displacement sensor for sensing positions of the displacement of the press ram during its working stroke, at least one force sensor for sensing compressive force applied by the press ram during the working stroke onto workpieces to be processed, and a control system which controls the working stroke in terms of displacement and compressive force. Parameters which indicate a successful course or completion of the pressing operation are dynamically adapted as a function of the profile of the compressive force versus the displacement of the press ram.
