The invention relates to a method for manufacturing an
electrode by adopting a multi-
station combining method and
machining a die inserted block for forming a
microstructure by using the
electrode, which belongs to the technical fields of special
machining and micromachining. The method comprises two steps, i.e. combined
electrode machining by electrical
discharge wire-
cutting and
microstructure machining by electrical
discharge forming. A plurality of
discharge stations of which the narrow slit widths sequentially and gradually decrease are machined on the same
electrode material by using the electrical discharge wire-
cutting, the gradually-decreased values of the narrow slit widths are equivalent to the variable quantity of electrode scaling dimensions from rough machining to finish machining in the electrical discharge forming. When the electrical discharge forming is carried out, the positions of a workpiece and the electrode are exchanged, the polarity of a
pulse power supply is reversed, and the workpiece carries out
servo-feeding machining on the electrode so as to finish discharging machining on each
station. The method provided by the invention has the effects and benefits that the error in repeatedly positioning caused by exchanging electrodes is avoided, the vibration error caused by the
servo motion of an electrode with a heavier weight and a larger volume is avoided, both the manufactured micro inserted block and the manufactured
microstructure are die steel and have high
hardness, long service lives, good surface quality and mirror effects.
