摘要： In an electric discharge machining apparatus with a wire-shaped electrode for machining a workpiece by causing electrical discharge in a gap between the wire-shaped electrode and the workpiece and controlling a machining feed speed so that the voltage across the gap is constant, the machining area of the workpiece is detected from the machining feed speed. The thus detected data representative of the machining area are applied to an arithmetic unit which operates to instruct optimum electrical machining conditions according to the machining area, whereby the workpiece is machined under the optimum electrical conditions at all times.

摘要： An electric discharge machining apparatus for cutting and shaping a workpiece into an article having a desired configuration in which the period of time required until the speed of a table carrying the workpiece becomes constant is made quite short. Comparator means compares a gap voltage between a wire-shaped electrode and a workpiece with a reference voltage to produce an error voltage. In one embodiment, a non-linear amplifier is disposed between the output of the comparator means and the input of an integrator. In the integrator, a clamping diode is coupled across an integrating capacitor so as to prevent the output of the integrator from becoming negative.

摘要： In an electric discharge machine, a pulse voltage is applied between a wire electrode and a workpiece to cause electric discharge between said wire electrode and said workpiece in a work liquid, and said workpiece is moved to said wire electrode depending upon the configuration of said workpiece and the degree of said electric discharge work to obtain a desired configuration. The movement of said workpiece can be controlled depending upon the speed signal corresponding to a gap voltage and the degree of the signal. The size of the work area is detected by the speed signal and a sharp corner work is carried out under a low energy by controlling the power source and the thickness variation work is carried out by increasing the energy in the case that the work area is increased and by decreasing the energy in the case that the work area is decreased.

摘要： A machining solution filtration apparatus for a machining device which includes: a filter, a filter medium which is arranged separately from the filter and supplied continuously; a unit for supplying a contaminated machining solution to the filter medium; a unit for generating a difference in pressure between the upper surface and lower surface of the filter medium; a unit for returning a machining solution filtered via the pressure difference to a filtered solution vessel; a unit for selecting the filter to allow the machining solution to be filtered only thereby for a predetermined period of time; a unit for detecting the presence/absence and/or remaining amount of the filter medium; and a unit for controlling the speed of supplying the filter medium. Accordingly, the apparatus is not only simple in structure and efficient in filtration, but also capable of reducing its running cost by extending the life of the filter and improving utilization of the machining device by reducing the frequency of replacing the filter. It is also easy in maintenance and readily repairable in the event of an abnormality.

摘要： A method and apparatus for detecting breakage of a wire electrode in an electric discharge machining apparatus, and an apparatus for carrying out this method, whereby breakage of the wire electrode is detected by detecting a change in a current from a detection power source provided separately from the main power source. Current from the detection power source is applied through the wire electrode by a roller in contact therewith. When the wire electrode is unbroken, current passes from the detection power source, through the wire electrode, to an optical coupling circuit, the secondary of the latter driving and indicating circuit. When the wire electrode breaks, the power flow to the primary of the optical coupling circuit is interrupted, thereby indicating breakage of the wire electrode.

摘要： A broken wire electrode 3 of a wire electrode electric discharge machining device is automatically repaired at the wire breaking position. After the used portion is cut away, the wire electrode 3 is fed toward the work 1. Upon detection of contact of the wire electrode 3 with the work 1, the feeding of the wire electrode 3 is stopped. A predetermined amount of deflection is obtained when the feeding of the wire electrode 3 is stopped. The wire electrode 3 is then moved horizontally relative to the work 1 within a predetermined range, until the end of the wire electrode 3 eventually falls into the machined groove 14 and the wire electrode 3 comes out of contact with the work 1. Thereafter the feeding of the wire electrode 3 is resumed to span the wire electrode 3 across the feeding-side wire guide unit 4 and the receiving-side wire guide unit 5. The attitude of the wire electrode 3 within the machined groove 14 is constrained downward by the water jet 7 sucked into the machining liquid nozzle 27 via the suction pump 30.

摘要： A wire electrode supplying apparatus for a wire electric discharge machine to effect the machining of a workpiece by inserting a wire electrode through the workpiece and allowing electric discharge to take place between the workpiece and the wire electrode. In this apparatus, a wire electrode feeding section is provided for inserting the wire electrode through the workpiece, as well as a feeding-side guide section and a receiving-side guide section are provided with the workpiece placed therebetween for the positioning of the wire electrode. The wire electrode is formed of a small-diameter wire, and the feeding-side guide section and the receiving side guide section are respectively provided with small openings for constraining the direction of its movement. The passage of the wire electrode through the small openings is aided by reducing the speed of feeding the wire electrode when the wire electrode passes through the small openings. A vertically movable jet nozzle is provided for allowing a working fluid to be jetted from the vicinity of the feeding-side guide section toward the receiving-side guide section so that the wire electrode after passing through the feeding-side guide section heads toward the receiving-side guide section. By starting the jetting of the working fluid after passing through the jet nozzle, the wire electrode is guided positively.
