Benefits of technology

[0006]An electroerosion machining system is provided in accordance with one embodiment of the invention. The 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 between the workpiece and the respective one or

Problems solved by technology

However, in some applications, during conventional electroerosion machining, due to insufficient flushing capabilities, the molten chips may interact with the workpiece being machined so as to stick or attach to the workpiece and transfer excess thermal energy into the workpiece resulting in heat affected zone on the workpiece and undesirable material properties.
This may be disadvantageous for subsequent electroerosion machining and the machining quality of the workpiece.

Abstract

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.

Description

BACKGROUND[0001]This invention relates generally to electroerosion machining systems and methods. More particularly, this invention relates to electroerosion machining systems and methods with higher flushing capabilities for machining workpieces.[0002]Electrochemical machining (ECM) and electrical discharge machining (EDM) are conventional processes for machining material in objects such as gas turbine components. ECM processes typically pass an electrical current in the gap between an electrode(s) and a workpiece for precision removal of amounts of material on the workpiece to achieve a desired final configuration thereof with substantially smooth surfaces. EDM processes circulate a dielectric liquid between an electrode(s) and a workpiece, and electrical discharges are generated in the gap between the electrode and the workpiece.[0003]Both ECM and EDM processes use electrical current under direct-current (DC) voltage to electrically power removal of the material from the workpiec...
