摘要： By utilizing a function of automatically selecting an automatic wire-connection parameter of a wire electric discharge machining apparatus, a default cutting condition is read, a cutting process is executed, and a wire-connection process is executed. As a result, when the wire connection is successful, the process in an automatic wire connection mode is ended. On the other hand, when the wire connection is unsuccessful, it is determined whether or not a parameter set selected by executing a cutting condition automatic selection process is adopted as a new default cutting condition. When the selected parameter set is adopted as the new default cutting condition, the selected parameter set is stored as the new default cutting condition, and the automatic wire connection mode is ended.

摘要： The methods and devices enable a reliable and rapid automatic threading process on spark-erosive wire-cutting machines with closed round guides without complicated entry of parameters. A heat-output control device with an optimized output characteristic curve is supplied from a DC voltage source of the erosion generator. Through an at least partial feedback loop of heating current and source voltage, the characteristic curve is modified in such a way that different wire types or different annealing lengths for the wire provide optimal results for stretching, straightening and separating the wire electrode without controlled intervention. With adaptive control it is possible to thread future wire types automatically without reprogramming.

摘要： When a wire electrode is arranged along a traveling path by manual operation, a motor M1 for feeding the wire electrode to a workpiece is driven in response to a predetermined torque command from a control section with a switch SW1 on a side a. The wire electrode is connected, and a motor M2 for delivering the electrode from the wire is driven at a predetermined speed, whereby the electrode is run. Then, the switch SW1 is shifted to a side b and a switch SW2 to the side a, and the motor M1 is subjected to torque control such that a tension on the wire electrode detected by a tension detector is equal to a command tension. When a variation of the tension on the wire electrode is converged, the switches SW1 and SW2 are shifted to the side b, speed control of the motor M1 is performed so that detected tension is equal to the command tension, and electric discharge machining is started.

摘要： A wire electric discharge machine and a wire electric discharge machining method in which a workpiece set posture is compensated for an error. After a workpiece is set and fixed on a workpiece table, an upper guide measures three or more three-dimensional positions that are not situated on one straight line on an upper surface of the workpiece, utilizing detection of contact with the upper surface. A unit normal vector Nincl (Xn, Yn, Zn) is obtained, and a shift amount Δshif (ΔU, ΔV) for shift from an originally set vertical position (U0, V0) to a corrected position (Uc, Vc) is calculated. In machining, the shift amount Δshif (ΔU, ΔV) is added to the position (U0, V0) to compensate for an angle error of a machined surface, and a deviation of a machined point position caused by inclination of the workpiece is collaterally compensated for as required by correcting the upper and lower wire guides. Thus, the machined shape cannot be distorted, and the workpiece set posture error can be compensated for.
