20110262771 | METHOD FOR ROUGHENING METAL SURFACES AND ARTICLE MANUFACTURED THEREBY - A method for surface roughening a metal work piece includes disposing a region of the workpiece to be roughened proximate to a counter electrode. The region of the workpiece to be roughened and the counter electrode are subsequently disposed together in an electrolyte. An electric potential with current flow is applied between the work piece and the counter electrode to roughen the metal surface to a desired roughness. | 10-27-2011 |
20120211357 | ELECTROEROSION MACHINING SYSTEMS AND METHODS - An electroerosion machining system comprises one or more electrodes configured to machine a workpiece, a power supply configured to energize the workpiece and the respective one or more electrodes, an electrolyte supply configured to pass an electrolyte, and a working apparatus configured to move the respective one or more electrodes relative to the workpiece. The electroerosion machining system further comprises a controller configured to control the working apparatus to machine the workpiece, and a removal agent configured to cooperate with the electrolyte from the electrolyte supply for removal of removed material from the workpiece. An electroerosion machining method is also presented. | 08-23-2012 |

20140034513 | ELECTROCHEMICAL MACHINING TOOLS AND METHODS - An electrochemical machining tool and method capable of rounding sharp edges that may be prone to cracking, for example, edge regions of cooling slots within dovetail slots of turbine wheels. The electrochemical machining tool includes an electrode and is secured to the component. The electrode of the electrochemical machining tool is inserted into a first slot, an electrolyte solution is applied between the electrode of the electrochemical machining tool and a second slot that intersects the first slot, an electrical potential is applied to the electrode and the turbine wheel to create a potential gradient between the electrode and the edge of the second slot, and material is removed from the edge of the second slot by displacing the electrode about and along the edge. | 02-06-2014 |
20150014281 | ELECTRODE AND METHOD FOR MANUFACTURING THE SAME - An electrode applied in electro-machining processes is provided. The electrode comprises a main body portion and at least one built-in internal flushing passage for introducing a flushing liquid to a volume between the electrode and a workpiece to be machined. The electrode is made by an additive fabrication process that enables specialized flushing for enhancing waste material evacuation and incorporate special material properties like zones of high electrical conductivity and thermal resistance. The fabrication process produces materials and geometries that could not otherwise be made using conventional processing. | 01-15-2015 |
20150135512 | BACKSTRIKE PROTECTION DURING MACHINING OF COOLING FEATURES - A method of machining a component including a substrate having an outer surface and an inner surface defining at least one interior space includes: disposing a distributed medium having a plurality of irregularly shaped particles in the interior space and forming at least one hole in the substrate, while the distributed medium is disposed within the interior space, such that the distributed medium provides backstrike protection for an opposing wall during the formation of the hole(s). Each hole extends through the substrate to provide fluid communication with the respective interior space; and the method further includes removing the distributed medium from the interior space. | 05-21-2015 |
20160045967 | METHODS AND SYSTEMS FOR ELECTROCHEMICAL MACHINING OF AN ADDITIVELY MANUFACTURED COMPONENT - 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. | 02-18-2016 |
20160101479 | METHODS FOR THE ELECTROEROSION MACHINING OF HIGH-PERFORMANCE METAL ALLOYS - A method of machining a work-piece formed of titanium-based material, using a machining apparatus, is described. The method includes the steps of providing an electrically-conductive electrode contained within a spindle assembly, in a pre-selected distance and position relative to the titanium-based work-piece; while electrically powering the electrode and the work-piece with a power supply. In the process, fluid electrolyte is circulated through at least two pathways in the machining apparatus—an internal conduit within the spindle assembly; and an external conduit. The charged electrode is moved relative to the work-piece in a plunging motion, to remove material from the work-piece at a relatively high rate, using a high-speed electro-erosion (HSEE) process. | 04-14-2016 |
