  • Machine tool and method for operating a machine tool
    Patent number: 7177720
    Abstract: A machine tool comprises a tool carrier moveable relative to a workpiece to be machined. A controller controls the relative movement of the tool carrier and the workpiece by means of a control program. If an unplanned event occurs during the operational movement of the machine, the relative movement of the tool and the workpiece is stopped, and a restart from a starting position is carried out later. The starting position is in this case approached along a trajectory, and the trajectory is determined automatically as a function of the machining operation in which the unplanned event occurred.
    Type: Grant
