Abstract
Electrodes, components, apparatuses, and methods for electrochemical machining (ECM) are disclosed. ECM may be employed to provide burr-free or substantially burr-free ECM of electrically-conductive workpieces (e.g. shrouds). As one non-limiting example, the electrically-conductive workpiece may be a shroud that is used as an electrical component in electronics boards. While the ECM components, apparatuses, and methods disclosed herein reduce burrs, ECM can provide imprecise machining and cause stray erosions to occur in the machined electrically-conductive workpiece. In this regard, the electrodes, components, apparatuses, and methods for ECM disclosed herein provide features that allow for precise machining of the machined electrically-conductive workpiece and also allow avoidance of stray erosions in the machined electrically-conductive workpiece.
