Method for operating a machine tool and machine tool

摘要

The method involves controlling and/or regulating clamping force acting on a clamped workpiece or a workpiece to be clamped at a respective position in a gear cutting machine (10) depending on current process and necessary process forces according to the current process. The workpiece is centered and clamped with the clamping force during loading and/or unloading the machine, where the force holds the workpiece in position for the workpiece positioning process. The force is increased before or during a movement of the workpiece from a loading- and unloading position into a machining position. An independent claim is also included for a machine tool.
