Abstract
A method of machining a pattern at a plurality of locations in a workpiece includes positioning a shaped electrode including the pattern at the plurality of locations in a sequence. In some embodiments, the sequence is random. The method further includes forming the pattern at each of the plurality of locations by passing electrical charges repeatedly between the shaped electrode and the workpiece and advancing the shaped electrode into the workpiece for a fraction of a full depth of the pattern. The method further includes repeating the positioning and forming steps a plurality of times until the full depth of the pattern has been formed at each of the plurality of locations.
