摘要: 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.

摘要: A system of manufacturing a component comprises forming a component on a conductive build plate. The component defines at least one access port and includes an inner surface that defines at least one internal passage. The system further includes forming at least one electrode within the at least one internal passage, wherein the at least one electrode is electrically isolated from the component. An electromotive force is applied to the at least one electrode to facilitate smoothing the inner surface.

摘要: A drilling tool for use in machining a conductive work piece is provided. The tool includes a body portion, a forward electrode coupled to the body portion, and at least one side electrode coupled to the body portion. When electric current is supplied to the forward electrode and the at least one side electrode, material adjacent to the forward electrode and the at least one side electrode is removed from the conductive work piece. Further, the forward electrode and the at least one side electrode are selectively operable to form a bore hole having a variable geometry that extends through the conductive work piece when the material is removed therefrom.

摘要: A fixture for an electro-chemical machining (ECM) electrode is provided. The fixture may include a clamp having a shape and size configured to selectively engage in at least a portion of a selected dovetail slot of a plurality of dovetail slots in a turbine wheel. An electrode mount positions an electrode head relative to the clamp such that the electrode head operatively engages a portion of the selected dovetail slot for electro-chemical machining of the portion. The fixture's electrode may act as a cathode for the ECM process. The fixture allows for ECM on site without removing a turbine wheel from a turbomachine.
