Abstract
A method of machining a workpiece to a predetermined depth using an electrode machining discharge apparatus including electrodes which wear during the machining process. The machining of a workpiece to a first level is effected, after which the electrodes are withdrawn and a refeed member having a surface matching that of the workpiece is positioned for engagement with the electrodes, followed by the electrodes engaging the refeed member to align the ends thereof, after which the machining operation continues. The machining operations are in increments less than the depth to which the machining is to be effective, and several alignments of the electrodes may be required.
