Abstract
A pulsed electrochemical machining (pECM) system including a tool body defining a tool axis and a proximal end and a distal end. The tool body includes one or more electrodes, each of the one or more electrodes defining a working surface at the distal end of the tool axis configured to face a workpiece. Electrolyte at least partially fills an interelectrode gap defined by the working surface at the distal end of the tool axis and a target surface of the workpiece. A first flow block coupled to the tool body and a second flow block coupled to the workpiece are configured to form at least one seal surrounding at least a portion of a perimeter of the interelectrode gap, and the at least one seal is configured to reduce or eliminate flow of the electrolyte out of the portion of the perimeter of the interelectrode gap.
