摘要： An apparatus for an electrochemical discharge machining process is provided. The apparatus includes a holder housing having, an inlet hole, an outlet hole, a first side, and a second side, and containing an electrolyte, a tool holder disposed at the first side, and a first electrode having a first end and a second end. The holder housing is configured to sealingly accommodate the electrolyte unless at least one of the inlet hole and the outlet hole is open. The first end is coupled to the tool holder and the second end passes through the second side. Since the apparatus is moved to a machining position of the work-piece by a worker, additional power for controlling the position thereof is not necessary. In addition, the apparatus is easy to carry and use because of its simple structure.

摘要： Spark-erosion machining method and machine implementing a machining gap, a process regulator, a numerical control system, a Nominal Trajectory. The latter describes the movement of the tool electrode relative to the part as it ought to proceed if no disturbance were to occur during the machining. Information contained in the Nominal Trajectory is used to define at least two control vectors Vg, Vp which orient, within the coordinate system XYZ, two independent regulation movements. The first, or Gap Vector Vg, defines the direction in which a first regulation movement of the axes of the machine must be performed to maintain the removal of material. The second, or Position Vector Vp, defines the direction in which a second regulation movement of the axes of the machining machine must be performed to correct a tool electrode position error. The respective amplitudes of the regulation movements are calculated in real time by the process regulator.

摘要： When forming metallic components, in particular three-dimensionally curved blades, which constitute a single piece with the blading of turbomachine rotor wheels, the linear oscillation of the electrode acting as a tool is superimposed by a circular oscillation, enabling the electrode to turn into the workpiece conformally with its shape. Further forming is performed by circular oscillation with circular feed in the one and/or the other direction. An embodiment of the corresponding apparatus comprises an electrode holder (9) with linear feed (Zvor) and linear oscillation (Zosz) and a workpiece holder (5) with circular oscillation (Cosz) and circular feed (Cvor).
