Patent number: 8999136Abstract: A Method and machine tool for compensating a wear of an electrode that machines a workpiece. The method includes selecting a current pocket from plural pockets of the workpiece; updating a wear compensation to be applied to the electrode for the current pocket based on wear compensation of a previous pocket, where the previous pocket is adjacent to the current pocket; and applying the updated wear compensation to the electrode for machining the current pocket.Type: GrantFiled: September 14, 2010Date of Patent: April 7, 2015Assignee: Nuovo Pignone S.p.A.Inventors: Ugo Cantelli, Garth M Nelson, Yuanfeng Luo, Yimin Zhan, Roberto Ciappi, Massimo Arcioni, Renwei Yuan

Patent number: 7824526Abstract: An apparatus and method for adapting a CNC milling machine for electroerosion machining. The apparatus includes a tubular electrode on the distal end of an adapter shaft. A tool holder on the proximal end of the adapter shaft is mountable in the chuck of a cutter spindle in the milling machine. The adapter shaft is rotatably mounted within a bearing and an electrical brush contact subassembly, both of which are supported by a bracket. The bracket is attached to the milling machine but insulates it from the tool electrode. The bearing supports the adapter shaft in alignment with the CNC spindle. An electrical power supply energizes the electrode and the workpiece for electroerosion in a gap between them. Electrolyte is circulated through the spinning tool electrode during operation. The CNC computer is configured to operate the machine, power supply, and electrolyte flow for electroerosion machining.Type: GrantFiled: December 11, 2006Date of Patent: November 2, 2010Assignee: General Electric CompanyInventors: Renwei Yuan, Yimin Zhan, Ugo Cantelli, Yuanfeng Luo, Garth M.
