Patent number: 9254530Abstract: A method for removing material from a component that is connected as an anode is disclosed. In an embodiment, an electrode that is connected as a cathode is guided to the component such that a gap is formed, an electrolyte is introduced into the gap, and a closed system is formed for the electrolyte by the formation of a duct. The electrolyte is continuously guided from an inlet opening to an outlet opening of the duct. Forming the duct, e.g., by guide elements that are mounted on the electrode, ensures that only those surface parts of the component to be machined from which material is to be removed enter in contact with the electrolyte while the other surface parts do not enter in contact with the electrolyte. Since the electrolyte is continuously guided across the surface, used electrolyte is continuously discharged along with residual matter while fresh electrolyte is delivered.Type: GrantFiled: December 5, 2008Date of Patent: February 9, 2016Assignee: MTU Aero Engines GmbHInventors: Erwin Bayer, Martin Bussmann, Albin Platz

Patent number: 8409423Abstract: A method for machining workpieces provides a machining electrode, which is guided at a specific distance to the workpiece. An electrolyte is provided between the workpiece and the machining electrode, through which an operating current flows between the machining electrode and the workpiece. The operating current results from an operating voltage (UA), which is produced at the machining electrode, the workpiece being connected to ground. To perform the machining procedure, the distance between the machining electrode and the workpiece is regulated and the operating voltage (UA) is determined in such a way that the resulting operating current is a DC current or a pulsed DC current—i.e., the operating voltage is a DC voltage of fixed or specific dimension. A measuring voltage (UM) is superimposed on the operating voltage (UA) for producing the operating current.Type: GrantFiled: October 13, 2005Date of Patent: April 2, 2013Assignee: MTU Aero Engines GmbHInventors: Erwin Bayer, Martin Bussmann, Thomas Kraenzler, Albin Platz, Juergen Steinwandel
