摘要： A wire cut electric discharge method adapted to make a slit (74), which is opposed to predetermined paths (70) each of which is straight or curved, in a workpiece (W) by electric discharge while moving one of a wire electrode (22) and the workpiece (W) relatively to the other along the predetermined paths on the basis of a NC program which is an aggregate of program blocks determined as a segment of the predetermined paths includes the steps of storing a position of a wire electrode which gets out of the predetermined paths after a process has been stopped, designating one segment out of an aggregate of segments of predetermined paths, determining a connecting position (82) in which the wire electrode is connected to the designated segment (80) with the position of the wire electrode the shortest distance away therefrom, and moving the wire electrode to the connecting position so as to return the wire electrode to predetermined paths. When a perpendicular line can be drawn from the position of the wire electrode to the designated segment, the connecting position corresponds to an intersection of the segment and the perpendicular line, and, when not, the connecting position corresponds to one of both ends of the segment which is nearer to the position of the electrode.

摘要： A wire-cutting machine with rotating electrode wire, comprises a differential device between a spindle (101) and a reel (103) to reel the electrode wire (112) in or out so that the working wire is rapidly rotated synchronously during its linear feeding. The wire-cutting machine according to the present invention has increased cutting thickness, and improved machining steadiness, precision and finishing surface due to the chip-discharge performed at whole machining area, and no electrode wire deformation happened. A taper cutting is possibly done in the machine, which also possesses the function of numerical control abrasive as a multi-machining.

摘要： A wire-electrode electrodischarge machine which supplies a pulsating current from a power supply circuit to a wire electrode through two feeder elements. The change of the discharge currents flowing through these two feeder elements with time (i.e. current differentiation value) is detected. The results of detection are used to obtain data relating to the discharge position and thus determine whether or not any change with time of the discharge position. In other words, whether or not a concentrated discharge occurs is judged. On the other hand, whether the difference between the currents in the two feeders is within a predetermined range to check for any wear or inferior contact in the feeder elements.

摘要： According to the present invention, feeding units (150a), (150b) having mechanisms for feeding wire electrodes (38a), (38b) of different diameters are provided for respective wire electrodes (38a), (38b), and these feeding units (150a), (150b) are transferred toward wire electrode supply paths by cylinders (151a), (151b) which are detachably engaged with the feeding units (150a), (150b), so as to automatically change the different-diameter wire electrodes (38a), (38b) in accordance with an object machining process, and carry out a machining operation with the machining conditions, required by the diameter of a wire electrode in use and an object machining process, selected automatically. Thus, a machining operation can be carried out by using an optimum wire electrode selected in accordance with a desired shape to which a workpiece is to be machined, and a wire electric discharge machining method of a high accuracy and a high machining efficiency can be obtained.

摘要： This invention provides a wire breakage position detector capable of displaying a zone in which wire breakage in a wire feed path occurs and the causes of the breakage in that zone that have been determined in advance. At the time of wire breakage, the value of a rewind quantity storage register is updated (S4, S5) in accordance with a pulse delivered from a rotary encoder following the rewind operation of the wire by a rewind motor while a breakage position detection voltage applied to the wire through a conductor is being detected by a microprocessor through an electrode disposed downstream of the conductor (S3). Thereafter, when the cut end of the wire passes the electrode, the motor rotation and the voltage application are stopped (S6-S8). The microprocessor judges (S9) in which zone of the wire feed path the wire is broken on the basis of result of comparison of the distance between each component disposed along the wire feed path and the electrode with the detected rewound quantity, and displays the zone of the wire breakage and the causes of breakage in this zone on a CRT screen in a message form.
