Abstract
A workpiece is electrodischarge machined using a machining apparatus having a workpiece holder, an electrode holder having an electrode mounted thereto, and a power supply providing an electrical voltage and current. The workpiece is mounted in the workpiece holder, and the electrode is positioned adjacent to a machining location of the workpiece. The method further includes furnishing a source of a flow of conditioned water, directing the flow of conditioned water from the source into the machining location of the workpiece, without submerging the machining location in a liquid, and applying a voltage from the power supply such that an electrical current flows between the workpiece and the electrode holder so that metal is removed from the workpiece into the flow of conditioned water.
