    摘要： In a molding die machining electrode 10, slit grooves of a molding die are machined with a slit groove forming part 22 having a substantially circular outer circumference by ranging hexagonal erected wall parts 23 in a row; while the inner circumference of a slit groove forming part 32 overlaps with the erected wall parts 23 in the outer circumference of the slit groove forming part 22, the outside slit grooves are machined with the slit groove forming part 32 having a substantially circular outer circumference. Similarly, the further outside slit grooves are machined with the slit groove forming part 42 of the third electrode 40. In such a manner, a plurality of the slit groove forming parts are radially divided and overlapping portions between the plurality of the slit groove forming parts are formed substantially coaxially with a molded body. The areas of the slit groove forming parts 22, 32, and 42 are designed to nearly similar values, suppressing the difference in wear of the electrodes.

    摘要： An electrical discharge machining electrode includes a body (11) and one or more shaped teeth (12). The one or more shaped teeth (12) of the body have a diffuser section and a metering section in electrical communication therewith. The body and the teeth may be formed by a process of photochemically etching a substrate made from an electrically conductive material.

    摘要： A layered anisotropically conductive element (11), a resistant element (12), and a feed element (13) constitute an electrode (14) for discharge machining. The layered anisotropically conductive element (11) includes conductive layers and low-conductive layers alternately laminated on each other, the conductive layers and the low-conductive layers being made of thin metallic plates coated with an insulative film. The layered anisotropically conductive element (11) has an anisotropic conductivity, in which the conductivity in a direction parallel to the low-conductive layers is much higher than that in a direction perpendicular to the low-conductive layers. The resistant element (12) is connected to one of layer-perpendicular end surfaces (11c) of the layered anisotropically conductive element (11). The feed element (13) is connected to the resistant element (12).
