Publication number: 20120006691Abstract: Conventional electrochemical machining process requires fixed shaped tool cathodes, which makes retooling time consuming and expensive. Flexible tool cathodes include elastically deformable cathodes that can deform in two or three dimensions and can adapt to the contour of the workpiece while the workpiece is moving relative to the flexible tool cathode. That is, the flexible tool cathode can perform tracing. Certain flexible tool cathodes can be also used for special configurations such corners and edges. The flexible tool cathodes can be used to polish, finish, or shape the workpiece through electrochemical processes.Type: ApplicationFiled: July 8, 2010Publication date: January 12, 2012Inventors: Yuefeng Luo, William Edward Adis, Laurence Scott Duclos
