  • Identifying and regulating the starting behavior during electrochemical machining of workpieces
    Patent number: 9790615
    Abstract: Disclosed is a method for the electrochemical machining of a workpiece, in which at least one electrode is situated adjacent to a surface to be machined and current pulses are generated in pulsed operation to ablate material from the workpiece. Before and/or at the beginning and/or during the electrochemical ablation, data of the current pulses are registered and analyzed to identify a starting phase or a transient phase comparable to a starting phase and/or to regulate the spacing of the electrode to the surface to be machined and/or the current flow during a starting phase or a transient phase comparable to a starting phase.
    Type: Grant
    Filed: October 20, 2014
    Date of Patent: October 17, 2017
    Assignee: MTU AERO ENGINES AG
    Inventors: Dirk Ruhlig, Markus Boxhammer
  • Method and device for removing a layer from a surface of a body
    Patent number: 9333623
    Abstract: A method for removing a layer made of a first material from a surface of a body made of a second material is disclosed. The body is subjected to a pressurized jet containing a blasting medium composed of particles, where the pressurized jet at least intermittently has an Almen intensity of at most 0.35 Almen A, preferably at most 0.3 Almen A and particularly preferably at most 0.25 Almen A.
