PCT No. PCT/EP92/01008 Sec. 371 Date Dec. 23, 1992 Sec. 102(e) Date Dec. 23, 1992 PCT Filed May 8, 1992 PCT Pub. No. WO92/19410 PCT Pub. Date Nov. 12, 1992.For the electric discharge machining of cutter plates (60) by means of an electrode wire (50) a respective cutter plate (60) is rotated under program control about a workpiece axis (A) and is adjusted rectilinearly with respect to the electrode wire (50) along at least one of three axes (X, Y, Z) of a rectangular coordinate system, among them one axis (X) which is parallel to the workpiece axis (A). During the machining of a flank (64) adjacent a cutting edge (66), the cutter plate (60) is rotated in such manner about the workpiece axis (A) that the point at which the electrode wire (50) intersects the cutting edge (66) always lies on a tool axis (E) which extends at right angles to the electrode wire (50) and to two axes (X, Y) of the coordinate system. During the machining of portions of the flank (64) which are located adjacent portions of the cutting edge (66) not in parallel with the workpiece axis (A), the electrode wire (50) is rotated about the tool axis (E).
