摘要： An EDM system in which a tool electrode is spacedly juxtaposed with a workpiece to define a machining gap which is substantially open directly to a region of atmospheric air. A non-inflammable (e.g. water-based) machining liquid is injected into the machining gap while electrical discharges are effected therein to electroerosively remove stock from the workpiece and to permit the injected liquid to be at least partially decomposed with a resultant formation of machining products which, growing in amount, are accumulated in a pile as debris on a surface of the workpiece adjacent the machining gap. A brush is provided to sweep the debris, and to substantially remove the piled machining products adjacent the machining gap.

摘要： An NC-EDM machine is safeguarded against feed errors arising from both mechanical and erosive-machining effects. The disclosed safety arrangement includes two detecting circuit units. The first unit is arranged to respond to NC-furnished driving command signals for producing a first detection signal representative of a commanded relative displacement to be effected between the tool electrode and the workpiece along a programmed machining path in a given time period. The second detecting unit is arranged to respond to effective electrical discharges caused in the EDM gap to produce a second detection signal representative of an actual relative displacement effected between the tool electrode and the workpiece along the path in the given time period. A comparator is connected to the two detecting units for comparing the first and second detection signals to produce an output signal indicative of a deviation of the actual advancement from the commanded advance.

摘要： A power-supply circuit for electrical machining of all types in which a tool is juxtaposed with a workpiece, the circuit having an alternating current input connected to the mains and receiving the alternating current at the mains' frequency, a rectifier connected to the input for converting the commercial alternating current to direct current, a solid-state switching device for converting the direct current to a high-frequency signal, a transformer whose primary winding receives the high-frequency signal and which produces a high-frequency output at a desired voltage level, a rectifier connected to this transformer at its secondary, and switch means for transforming the direct-current output of the latter device into the machining signal. The system permits the transformer to be of substantially reduced size by comparison with transformers used in earlier high-power electrical machining systems.

摘要： A wire state of use indication apparatus for use with a traveling-wire electroerosion cutting machine is disclosed in which a sensing unit instantaneously responds to the rotation of a roller disposed in the wire travel path and rotated with the electrode wire travelling in bearing contact with the roller. The number of the rotations is counted to produce a sensing signal which represents the cumulative number of rotations of the roller a number which in turn represents the amount of the electrode wire which has been drawn out of the wire storage rool by a given time instant during a given cutting operation. A processing circuit is provided to process the sensing signal with an input setting signal representing the amount of the electrode wire stored in the reel prior to the commencement of the cutting operation to produce an output signal which represents the amount of the electrode wire remaining in the reel at that time instant. The sensing unit may also provide a further sensing signal representing the instantaneous rate of rotation of the roller which rate in turn represents the instantaneous rate of drawing the wire out of the reel.

摘要： Wire-cut electroerosion method and apparatus whereby breakage of an electrode wire is substantially prevented by limiting air-bubbling in the cutting zone from the electrode wire traveling through a liquid-machining medium. The air-bubbling is limited by cleaning the electrode wire advancing from its storage reel prior to its entry into the cutting zone supplied with the liquid machining medium. The electrode wire may be cleaned by brushing the wire between the storage reel and the wire-braking roller and thereafter cleansed by a showering fluid. Preferably, ultrasonic vibrations are applied to the showering fluid. The braking rollers and a wire-conducting roller are also provided with brushes to prevent contaminants from being introduced onto the cleaned electrode wire by these rollers.
