摘要： An electrode applied in electro-machining processes is provided. The electrode comprises a main body portion and at least one built-in internal flushing passage for introducing a flushing liquid to a volume between the electrode and a workpiece to be machined. The electrode is made by an additive fabrication process that enables specialized flushing for enhancing waste material evacuation and incorporate special material properties like zones of high electrical conductivity and thermal resistance. The fabrication process produces materials and geometries that could not otherwise be made using conventional processing.

摘要： There is provided a method for manufacturing a honeycomb structure forming die including a liquid groove forming step for forming linear processing liquid grooves 3 whose width is smaller than that of the slit 5, in positions for forming the slits 5 for forming the partition walls 41 of the honeycomb structure 40 by subjecting the kneaded clay to extrusion in one side end face 7 as a kneaded clay forming face 17 of a plate-shaped die substrate 2. An introduction hole forming step for forming introduction holes 4 for introducing the kneaded clay is performed before or after the liquid groove forming step. Slits 5 communicating with the introduction holes 4 are formed by performing comb-like electro-discharge machining by a comb-like electrode 21 where plate-shaped protrusion electrodes 23 corresponding with the slit 5 width are disposed in positions including the processing liquid grooves 3.
