摘要： In a machining liquid processing unit in an electric discharge machine selectively using two types of machining liquid of a first machining liquid not containing therein powder material and a second machining liquid containing conductive powder material mixed therein, a movable shooter is movably provided between a first position where a machining liquid is flown to a first storage section in a machining liquid vessel and a second position where a machining liquid is flown to a second storage section, and the machining liquid discharged from a machining liquid discharge port formed in the machining liquid vessel in an electric discharge machine is selectively flown to either of the first storage section or the second storage section by the movable shooter.

摘要： A method of improving an internal surface topography of a manufactured workpiece includes filling a workpiece with an electrically conductive magnetorheological (MR) fluid. The workpiece includes at least one internal feature having an inner surface with at least one irregularity. The method further includes converting the MR fluid into a rigid MR material, applying a voltage to the rigid MR material, and ablating the inner surface in response to the voltage to remove the at least one irregularity.

摘要： The present method for machining a part includes wire electro-discharge machining the part to create a recast layer, and then removing a zinc content of the recast layer without substantially altering the remainder of the initial composition make-up of the recast layer. The final composition make-up of the recast layer is substantially identical to the initial composition make-up except for the removed zinc content.

摘要： In the present invention, when performing electrical discharge machining on a workpiece via an electrical discharge machine that has an electrode holder and an electrode guide, a workpiece model and an electrode-guide model are generated in advance, an interference-start position at which the electrode-guide model starts interfering with the workpiece model when the electrode-guide model is moved towards the workpiece model along an axis line (CLa) is calculated, and a position obtained by moving the electrode-guide model a prescribed distance away from the workpiece model, starting at the interference-start position, is set as an electrode-guide position. With the electrode guide positioned at the electrode-guide position, the electrode holder is moved downwards in order to move an electrode downwards toward the workpiece surface, and electrical discharge machining is performed on the workpiece.

摘要： A wire electric discharge machining apparatus that machines a workpiece by using a wire supported between a lower arm and an upper arm. The apparatus includes a surface plate that has a vacant inner area in which the wire moves and supports part of the workpiece with an outer area thereof. The apparatus further includes a bellows that extends through a side surface of a casing of a machining bath, enclosing part of the lower arm, wherein a first end of the bellows that is on a side of the machining bath is attached to the lower arm so that the bellows does not get in under the inner area, at whatever position the wire machines the workpiece.

摘要： A method for machining materials difficult to cut by EDM conventional processes and consisting in providing contamination of the machining or dielectric fluid used in the course of electrical discharge machining with particles of a metal or metallic alloy of low vaporization temperature selected, for example, from the group consisting of zinc, cadmium, tin, lead, antimony and bismuth. The contamination particles are obtained directly from a surface coating placed directly on the electrode tool or from an additional piece of metal or metallic alloy which is electro-eroded at the same time as a cut is effected by the electrode tool in an electrode workpiece, and the contaminated fluid is circulated in the machining zone between the electrodes, the contaminated fluid facilitating the triggering of the electrical discharges in the machining zone and providing an increase of the machining rate, or material removal rate.
