Pulsed electrochemical machining of turbine components

Abstract

A method for pulsed electrochemical machining (pECM) a turbine component, comprising: generating a pulsed direct current between one or more electrodes of a machining tool and the turbine component, wherein the machining tool comprises a tool body defining a tool axis, the tool body comprising the one or more electrodes, each of the one or more electrodes comprising an electrically conductive material and defining a working surface at a distal end of the tool axis configured to face the turbine component; delivering an electrolyte into an interelectrode gap between the working surface of the one or more electrodes and a target surface of the turbine component; and positioning the working surface of the one or more electrodes relative to the target surface of the turbine component to remove material from the target surface of the turbine component.
