摘要： The present disclosure provides an electrochemical machining apparatus including a pressurized tank, a cap, a stabilizing plate, a guiding element, and an electrode. The pressurizing tank has a top surface and a chamber, wherein the top surface is disposed with an opening and a limiting portion. The cap fits in the opening and is limited by the limiting portion to seal the pressurized tank. The stabilizing plate is spaced from the top surface or the cap by a distance. The guiding element penetrates the stabilizing plate to connect with the cap and provides a channel to the chamber. The electrode is guided by the guiding element and penetrates the chamber via the channel. When the electrode processes a workpiece in the chamber during an electrochemical machining operation, the cap takes a pressure generated during the electrochemical machining operation, and the stabilizing plate stabilizes the electrode and the guiding element.

摘要： A method includes applying a force to elastically deform at least a portion of a superalloy turbine blade from a relaxed, initial position to an elastically deformed position. The at least a portion of the superalloy turbine blade has a curvature in the elastically deformed position not present in the relaxed, initial position. A hole is drilled generally span-wise through the at least a portion of the superalloy turbine blade in the elastically deformed position, and when the force is released, the superalloy turbine blade returns to the relaxed, initial position and the hole takes on a hole curvature within the at least a portion of the superalloy turbine blade.

摘要： An electrochemical machining system for machining a conductive work piece is provided. The system includes a drilling tool configured to remove material from the conductive work piece. The drilling tool is configured to advance within the conductive work piece along a tool path to form a bore hole having a variable geometry that extends through the conductive work piece when the material is removed therefrom. The system further includes an inspection device configured to determine a position of the drilling tool along the tool path, and a controller configured to communicate with the inspection device. The controller is further configured to compare the tool path to a nominal tool path, and determine a position error of said drilling tool, the position error defined by a difference between the tool path and the nominal tool path.

摘要： An electrochemical machining device includes an electrode bundle, an electrode sleeve used for receiving the electrode bundle therein, and an electrolytic tank. The electrode bundle includes a number of columnar electrodes. Each of the columnar electrodes can move along an axial direction of the electrode sleeve. The electrode sleeve includes sidewalls, and two pressing plates positioned corresponding to two adjacent sidewalls. The sidewalls of the electrode sleeve include a number of screws to adjust a distance between the pressing plates and the corresponding sidewalls. The pressing plates can be moved to press the electrode bundle, and fix the electrode bundle between the pressing plates and the corresponding sidewalls of the electrode sleeve. A shape of the electrode bundle can be adjusted according to a shape of a molding surface.

摘要： A device and a method for producing a blade airfoil from a workpiece which comprises at least two gaps and at least one blank arranged between the two gaps, wherein the blank comprises two opposite lateral faces which are bounded by a base, a top and a first and a second edge. The method comprises: (a) arranging the first and second electrodes in the first and second gaps, the surface of the workpiece forming an annular space surface at the gaps, (b) applying a positive voltage to the blank and applying a negative voltage to the first and second electrodes, (c) moving the first and second electrode in the direction of the first and second lateral faces. Step (b) is preceded by passing electrolyte between the two electrodes over the top toward the base.
