PURPOSE:To mass-productively perform cutting of a complicated shape with improvement of the surface roughness of the cutting surface, by executing electric discharge machining on the cutting surface by the following work with one part of the metal work cut by laser cutting as the electrode, after laser cutting. CONSTITUTION:In laser cutting, a fitting hole 20 in the specific shape to the chuck of an electrode head 9 is formed at a specified position of an initial work 18 and thereafter a required work shape is subjected to cutting. Then, the fitting hole 20 of the work (mold electrode) 19 whose one part is cut off is correctly arranged to the lower part of an electrode head 9 and the mold electrode 19 is fixed to the electrode head 9. A work liquid is then poured into a work tank to perform diesinking rocking electric discharge machining. After completion of the electric discharge machining, the work liquid is recovered from the work tank and a series of metal compound work is completed. |
