Abstract
In some examples, a pulsed electrochemical machining (pECM) system including a first tool body including a first electrode defining a working surface at a distal end of the tool axis configured to face a workpiece and a second tool body including a second electrode defining a working surface at a distal end of the tool axis configured to face a workpiece. The system includes a mechanical system configured to position the working surface of the first tool body relative to the workpiece and configured to position the working surface of the second tool body relative to the workpiece. The system includes an electrolyte system configured to supply electrolyte to a first interelectrode gap and a second interelectrode gap and a power supply configured to generate a pulsed direct current between the first tool body and the workpiece and the second tool body and the workpiece.
