Abstract
This invention consists in a method of repairing a broken wire on a wire cut electric spark machine in which a wire broken on a cutting path during electric spark cutting process is repaired and the repaired wire is returned to the position at which the wire was broken. After connecting (S1) the ends of the broken wire, a discharge state in which electric discharge current is smaller than that at the time of machining the wire is selected (S2, S3) and the wire is returned to the position at which the wire was broken along the cutting path (S4, S5, S6). With the broken wire returned to the initial position in a discharge state that electric discharge current is smaller than that during machining, another process is applied to the distorted work so as to correct distortion and chips can be removed by electric discharge. Thus, the wire is prevented from being broken again and can be quickly returned to the position of the wire breakage.
Description
明 細 書 ワイヤカ ツ ト放電加工機の断線修復方法 技 術 分 野 Description Wire disconnection EDM machine disconnection repair method Technical field
本発明は、 放電加工の加工経路途中で断線したヮィャを結 線後に断線位置に復帰させるヮィャカ ツ ト放電加工機の断線 修復方法に関する。 背 景 技 術 The present invention relates to a method for repairing a broken wire in an electrical discharge machine, which restores a broken wire in the middle of a machining path of electrical discharge machining to a broken position after the connection. Background technology
ワイヤカ ツ ト放電加工機はヮ一クとワイヤとの間にパルス 的放電を発生させ、 ワークの一部を溶解し、 この溶解した部 分をノズル等で吹き飛ばしていき、 これを連続動作させて、 ワークを所望の形状に仕上げるものである。 The wire-cut electric discharge machine generates a pulsed electric discharge between the peak and the wire, melts a part of the work, blows this melted part away with a nozzle, etc., and operates it continuously. A work is finished to a desired shape.
ワイヤカ ッ ト放電加工機でワークを加工中に、 ワイヤが断 線した場合、 従来はワイヤを一度加工開始点に戻し、 そこで ヮィャを結線した後、 既に加工した加工経路に沿ってヮィャ を断線した位置まで苠していた。 Conventionally, if a wire breaks during machining of a workpiece with a wire-cut electric discharge machine, the wire is once returned to the machining start point, the wire is connected there, and then the wire is broken along the already machined machining path. To the position.
また、 ワイヤ自動結線装置のついた加工機のように、 断線 したワイャを取り除き、 加工開始点で新しいヮィャを再び結 線して、 断線位置で自動的に再加工するものもある。 Also, there is a machine such as a machine with an automatic wire connection device that removes a broken wire, reconnects a new wire at the processing start point, and automatically reprocesses at the breaking position.
しかし、 ワークを加工するとワ -クの内部歪み等により、 ワークが変形する場合がある。 また、 ワイヤの通過した後の 加工経路には加工くずが残されていることがある。 従って、 従来のようにワイャ結線後にこの加工経路に沿ってワイャを
戻してやろうとすると、 ヮィャが加工くず又は歪んだヮ一ク 等に引っ掛かり、 断線した位置に戻る途中で再び断線してし まうという問題があった。 発 明 の 開 示 However, when the work is processed, the work may be deformed due to the internal distortion of the work. In addition, processing chips may be left in the processing path after the wire has passed. Therefore, wires are connected along this machining path after wire connection as in the past. If the wire is to be returned, there is a problem in that the wire is caught by processing scraps or distorted cracks and the wire is broken again while returning to the broken position. Disclosure of the invention
本発明はこのような点に鑑みてなされたものであり、 放電 加工時に断線したワイャを加工開始点で結線後、 断線位置ま で戻す場合に、 加工くず又は歪んだワークによってワイヤが 再度断線することなく高速に断線位置に復帰できるワイヤ力 ッ ト放電加工機の断線修復方法を提供することを目的とする。 本発明では上記課題を解決するために、 The present invention has been made in view of such a point, and in a case where a wire that has been disconnected during electric discharge machining is connected at a machining start point and then returned to a disconnection position, the wire is disconnected again due to processing waste or a distorted work. It is an object of the present invention to provide a method for repairing a disconnection of a wire-cut electric discharge machine capable of returning to a disconnection position at a high speed without any problem. In the present invention, in order to solve the above problems,
放電加工の加工経路途中で断線したヮィャを結線後に断線 位置に復帰させるワイヤ力ッ ト放電加工機の断線修復方法に おいて、 結線後の前記ワイヤを前記加工時よりも小さな放電 電流の放電状態に維持しながら前記加工経路に沿って前記断 線位置まで復帰させることを特徵とするワイヤカツ ト放電加 ェ機の断線修復方法が提供される。 A wire force that restores a broken wire in the middle of the machining path during electrical discharge machining to a disconnected position after connection, in a method for repairing a broken wire in a wire-cut electric discharge machine, where the discharged wire has a smaller discharge current than that during the machining. A method for repairing a disconnection of a wire cut discharge machine, characterized in that the wire cutting discharge machine is returned to the disconnection position along the machining path while maintaining the cutting position.
結線後のワイャを加工時よりも小さな放電電流の放電状態 に維持しながら加工経路に沿って断線位置まで復帰させる。 従来のようにワイャを加工経路に沿って断線位置までそのま ま復帰させると、 ヮィャが歪んだワーク又は加工くずに引つ 掛かり、 断線した位置に戻る途中で再び断線してしまう。 一 方、 加工時と同じ放電状態で復帰させると加工経路で再び放 電加工が行われたと同じ状態になり、 加工面の精度が劣化し、 加工誤差が増大する。 そこで、 本発明のように加工時よりも
小さな放電電流の放電状態で復帰させることによって、 歪ん だワークに対してはその歪みを修正するような加工が行われ、 また、 加工くずに対してはそれを放電によって除去すること ができる。 従って、 ワイヤは再度断線することはなく、 高速 に断線位置に復帰することができる。 図 面 の 簡 単 な 説 明 The wire after the connection is returned to the disconnection position along the machining path while maintaining the discharge state with a smaller discharge current than during the machining. If the wire is returned to the disconnection position along the machining path as it is in the past, the wire will be caught by the distorted work or processing waste, and will be disconnected again while returning to the disconnected position. On the other hand, if the discharge is resumed in the same discharge state as during machining, it will be in the same state as when discharge machining has been performed again in the machining path, and the accuracy of the machined surface will deteriorate, and machining errors will increase. Therefore, as in the present invention, By recovering in the discharge state with a small discharge current, the work that corrects the distortion is performed on the distorted work, and the processing waste can be removed by the discharge. Therefore, the wire does not break again and can be quickly returned to the break position. Brief explanation of drawings

Immediately, the machining conditions suitable for moving the machined path once again in the discharge state are selected and output to the machine. This processing condition is a discharge current value smaller than the discharge current at the time of disconnection, and is a discharge condition that can remove dust. The actual machining conditions are determined in consideration of the wire material, diameter, wire tension, feed speed, machining fluid specific resistance, machining fluid injection amount, distance between guide works, etc.
〔 S 3〕 S 2で設定された放電条件で放電を開始する。 [S3] Discharge starts under the discharge conditions set in S2.
