    Abstract: Disclosed are a multi-channel electrochemical machining device and method for a blisk, and relate to the technical field of blisk electrochemical machining. The multi-channel electrochemical machining device for a blisk comprises an electrolytic bath used for accommodating an electrolyte, a blisk workpiece, a tube electrode and a top cover plate. The top cover plate is located above the blisk workpiece. An electrolysis chamber used for the tube electrode to electrolyze the blisk workpiece is formed between the lower surface of the top cover plate and the surface of the blisk workpiece. The electrolysis chamber communicates with the electrolytic bath. A drainage seam communicating the electrolysis chamber and the electrolytic bath along the axial direction of the blisk workpiece is formed in the upper surface of the top cover plate.

    Abstract: An electrochemical machining assembly for boring a passage in an electrically conductive workpiece. The electrochemical machining assembly includes an electrochemical machining tool having a telescoping collar with an articulating head coupled thereto. The telescoping collar is actuated between a contracted configuration and an extended configuration to advance the telescoping collar stepwise in the passage. The articulating head is tiltable relative to the telescoping collar to determine a direction of the passage. The electrochemical machining assembly is configured to remove material from the workpiece upon application of a voltage between the articulating head and the workpiece via a circulating electrolyte fluid to lengthen the passage.

    Abstract: The invention relates to a method for the electromechanical machining of a component with at least one electrode which has a first working face with an outer contour which is shaped so as to form a gap complementary to a surface, to be produced by the electrochemical machining, of the component and which has a second working face which is able to be arranged at an edge of the produced surface of the component. In the method, first of all the component is provided, and the first working face of the electrode is positioned in a first machining position with respect to the component. Then, the component is machined with the first working face in order to produce the surface, before the machining of the component with the first working face is ended at a predetermined position. Subsequently, the component is machined with the second working face of the electrode.

    Abstract: A machining apparatus is disclosed, which includes a curved outer conduit, a curved rotary electrode and a driving motor. The outer conduit has a cavity and a fluid inlet in fluid communication with the cavity. The electrode includes a flexible shaft positioned in the cavity and having a first end and a second end, and a machining head having a fluid outlet in fluid communication with the cavity and electrically connected with the first end of the flexible shaft to be powered via the flexible shaft. The motor is mechanically coupled to the second end of the flexible shaft for driving the flexible shaft to rotate. A machining system is also disclosed, which includes the machining apparatus, a power supply for powering the flexible shaft, an electrolyte supply for providing electrolyte to the fluid inlet and a machine tool onto which the outer conduit and the motor are positioned.

    Abstract: A method of controlling a working gap between one or more cathodic tools and an anodic workpiece in an electrochemical material dissolution process, the method comprising: providing a cathodic tool and an anodic workpiece defining a working gap therebetween, the cathodic tool and the workpiece being at least partially immersed in a conductive electrolyte solution; providing a negative electrical potential to the cathodic tool; monitoring one or more of the electrical potential, current, current density and charge between the cathodic tool and the anode to determine the working gap between the cathodic tool and the anode; and, controlling one or more process parameters to maintain one or more of the working gap and electrochemical working conditions between the cathodic tool and anodic workpiece at a targeted value.
