PURPOSE:To prevent the phenomenon of short-circuit from occurring, and to prevent machining hindrance from occurring, by filling a filler into a cut groove formed in a workpiece by a cutting process, and by holding a scrap produced from the workpiece by means of the filler. CONSTITUTION:A cutting machining process is carried out by a wire electrode 3 from a machining starting hole 26 in the direction of the arrow (a) to form a cut groove 3'. When the electrode 3 reaches at, for example, the position B, the cutting machining process is temporarily interrupted, and a filler 23 is filled into the cut groove 3' at, for example, the predetermined positions C, C' from a nozzle in a filler feed device (which is not shown), and is secured. A scrap 1' is held by means of the filler, and therefore, will not move. Then the remaining part may be cut and removed. |
