A method for operating a machine tool such as a press includes determining and providing/storing energy for machining a work piece as available energy by considering a first value of the energy to be applied of at least one element of the machine tool to store energy. Available energy provided in a section or in a partial section of a motion sequence of a stroke element determined for machining the work piece is gathered. Part of the available energy of the energy to be applied for machining the work piece from an energy potential provided/stored in the machine tool is used. A second value for an effective required energy is formed via at least one energy-storing element.
