A workpiece is contour-machined by axially transporting an electrode wire through the workpiece between spaced apart wire support/guide members while advancing the workpiece to cut a groove progressively along a programmed closed-loop path of predetermined contour. The workpiece is relatively displaced w.r.t. the electrode wire to advance the wire along the closed-loop path, first along an upper path, then along a lower path, and finally along the remaining portion of the upper path. Used for severing a workpiece into a central portion and a peripheral portion by electroerosion. The severed central portion falls and rests on the peripheral portion without hitting or squeezing the electrode wire against the walls of the peripheral portion.
