An electrode for machining a pattern in a workpiece has a conductive body with a lattice of closed cells and a plurality of open cells. The open cells are positioned at an edge of the lattice of closed cells. The closed cells are defined by interconnected webs, and the open cells are defined by fins extending from the interconnected webs. A thickness of the fins is less than a thickness of the webs. In use, the electrode is positioned at a plurality of locations on the workpiece, such that a position of the fins of the electrode at each location overlaps a position of the fins of the electrode at an adjacent location. The pattern is formed at each of the plurality of locations by passing electrical charges repeatedly between the electrode and the workpiece and advancing the electrode into the workpiece. |
