PURPOSE:To efficiently draw wire-cutting electric discharge lines in each process for manufacturing a plurality of parts of the same form, by moving the processing locus reversely to jointly use a single processing line for adjacent parts. CONSTITUTION:A wire electrode 4 is moved in an electric discharge locus 3 from a starting hole 8 to a point (a) as shown by arrows. After the electrode 4 is moved from the point (a) to another (b), the electrode is moved back to the point (a) and then moved to a point (d) through a point (c). The electrode 4 is thereafter displaced back from the point (d) to the preceding one (c) and moved therefrom to a point (e). The electrode 4 is then moved from the point (e) to a point (f) and backed to the point (e). The electrode 4 is thereafter moved from the point (e) to a point (h) through a point (g). Backing in the electric discharge locus is thus effected at the beginning and end of processing of parts 2. Electric discharge machining is caused to leave small uncut portions 10. The wire electrode 4 is finally returned to the starting point 8. |
