摘要： A method of controlling a wire cut discharge machine which improves machining accuracy when a corner portion is machined. When a portion to be machined is a corner portion, the pressure and/or quantity of cutting fluid to be fed to a gap between a work and a wire electrode is reduced for only a specific zone. Setting of this zone and feed regulation of cutting fluid are determined on the basis of an allowable radius and the shape and dimension of the corner portion. The discharge energy to be supplied between the work and the wire electrode is decreased simultaneously with the feed regulation of the machining liquid in the zone described above.

摘要： This invention relates to a method of preparing NC data for coreless machining in wire cut discharge machining using an automatic programming apparatus. A programming apparatus which reads the profile (C1) of a machining area (A1), a wire connecting position (PO) and a maximum cut-in quantity from a PERT program prepares NC data for moving a wire from the wire connecting position (PO) to a machining area center position (P1) (S1) while effecting discharge machining, determines a spiral tool orbit consisting of circular orbits (PS1 ∩ PS3) each having a shape similar to a figure expressing the profile of the machining area and spaced apart mutually by a maximum cut-in distance and linear orbits connecting the adjacent circular orbits with one another and prepares NC data for making rough machining along the linear orbits and circular orbits inside a finish machining area inner peripheral curve (C2) (S2). When the NC data for making final rough machining along the inner peripheral curve is produced (S3), the cut-in distance from the circular orbit (C3) adjacent to the inner peripheral curve is limited to the distance between them. Finally, NC data for making finish machining along finish machining orbits (C4, C5, C1) outside the inner peripheral curve determined on the basis of a finish margin and the number of finishes in the PERT program is prepared (S4).

摘要： A wire electric discharge machining method for improving a machining precision when machining a corner portion. A speed is gradually reduced starting at point A until the machining of a corner portion C-D is initiated, and machining is performed on the corner portion C-D at a constant feed speed. Then, the machining feed speed is gradually increased starting at point D where the machining of the corner portion has been completed until the original speed is restored at point F. In accordance with this change in feed speed, the off-time of a voltage applied between a wire and a work is increased starting at point B, reduced starting at point E after the machining of the corner portion is completed, and restored to the original level at point F. Furthermore, the flow rate of processing liquid is also reduced with the progress of machining of the corner portion. This process is controlled in accordance with the radius curvature of the corner portion by automatically changing a feed speed along the corner portion, off-time and flow rate of processing liquid. There is little deflection of the wire electrode at the start and during the machining of the corner portion, whereby the precision with which corner portion is machined is improved.
摘要翻译：一种用于在加工拐角部分时提高加工精度的线材放电加工方法。从点A开始逐渐降低速度，直到角部C-D的加工开始，并且以恒定的进给速度对角部C-D进行加工。然后，从拐角部分的加工已经完成的点D处逐渐增加加工进给速度，直到原点在点F处恢复。根据进给速度的这种变化，施加的电压的关闭时间线材和工件之间的距离B点开始增加，拐角部分的加工完成后从点E开始减小，并在点F恢复原来的水平。此外，处理液的流量也随着角部加工的进度。通过自动改变沿着角部的进给速度，处理液的离开时间和流量，根据角部的半径曲率来控制该处理。在开始和加工角部时线电极几乎没有偏转，从而提高了角部加工的精度。

摘要： A method of correcting short-circuiting of a wire-cut electrical discharge machine, wherein not only the short-circuiting in the direction of wire advancing but also the short-circuiting in the direction perpendicular to the advancing direction can be quickly and reliably corrected. When the short-circuiting is detected, a wire is retracted by a predetermined distance L0 (S1, S2). When the short-circuiting is not corrected at this time, it is determined that the short-circuiting in the direction perpendicular to the advancing direction of the wire has taken place (S3). Then, a shape of machining and a position of the wire are determined to make an optimum retracting control (S4, S5), to thereby determine a retracting direction and a retracting distance of the wire (S6). The optimum retracting control of the wire is performed on the basis of the retracting direction and the retracting distance (S7), and, when correction of the short-circuiting is detected, the wire is returned to the initial position where the short-circuit is detected (S8, S9), whereby the electrical discharge machining is continuously performed (S10).
