The outsole mold of the shoes has been manufactured using electro-discharge machining by graphite electrode or using casting etc. The study is concerned with the pattern design for the outsole of shoes by CAD, the modeling and the generation of NC data by CAM system and the machining by CNC machining center. The ball end mill and the engraving cutter is used as cutter and the cutting conditions are adjusted according to the shapes and sizes of the cutter and part in cutting. The method showed the possibility coping with the rapid change of shoes industry and proposed the possibility for higher productivity and quality on mold-manufacturing of shoes outsole.
