摘要： A wire electric discharge machining apparatus is provided. The wire electric discharge machining apparatus includes an upper support that supports an upper guide unit that guides a wire electrode on an upper side. The upper support includes an arm having a lower end provided with the upper guide unit, an axis drive portion moving the arm in at least one axial direction and made of a material that has a larger coefficient of linear expansion than ceramics, and an adjustment block connecting the arm and the axis drive portion and made of ceramics. The adjustment block is fixed at a position where a displacement of the upper guide unit caused by expansion and contraction of the upper support is suppressed by a bimetal effect occurring on a fastening surface of the axis drive portion and the adjustment block.

摘要： A cutting tool assembly using a machined tool operating in a plunge mode of electrical discharge machining to make microreplicated features in a work piece having a complex surface. The microreplicated features can be non-adjacent and can have any geometric configuration and micron-scaled dimensions, as determined by the microstructured features in the tool. The machined work piece can be used as a master tool in order to make microreplicated articles such as optical films, friction control films, plasma display panel molds, or micro-fasteners.

摘要： An electrochemical discharge machining device includes a base, a sensor disposed on the base, a shaft rotatably disposed on the base, an electrode disposed at one end of the shaft and contacting with a work piece, an isolating element disposed between the sensor and the shaft, and a control module connected to the sensor. Current flows to the electrode via the shaft to machine the work piece, and the force exerted on the electrode by the work piece is transmitted via the shaft and the isolating element to the sensor converting the force into a signal sent to the control module for raising or lowering the base to maintain contact between the electrode and the work piece. The sensor serves as a detecting mechanism to ensure appropriate contact between the electrode and the work piece.
