PROBLEM TO BE SOLVED: To provide a control device with a wire replacement function for a wire electric discharge machine, in order to focus on a wire electrode among consumables of a wire electric discharge machine and realize wire electrode replacement without stopping continuous operation and without requiring manpower when the wire electrode has reached replacement time.SOLUTION: A control device 10 for a wire electric discharge machine includes: wire residual life time monitoring means 11; electric discharge machining time calculation means 12; and wire replacement timing determining means 13. Accordingly, the control device recognizes timing at which electric discharge machining is interrupted, and controls the wire electric discharge machine according to this timing so that program operation is temporarily stopped (program operation stopping command means 14), a wire electrode is cut (wire cutting means 20), the wire electrode is automatically replaced using wire replacement means 21, and so that, after the wire electrode replacement, the wire electrode is connected (wire connection means 22) and the program operation is resumed (program operation resumption command means 15).SELECTED DRAWING: Figure 1 【課題】ワイヤ放電加工機の消耗品の中でワイヤ電極に着目し、ワイヤ電極が交換時期に達した際に、連続運転を停止することなく、また、人手を介することなくワイヤ電極交換を行えるようにするために、ワイヤ交換機能を有するワイヤ放電加工機用の制御装置を提供する。【解決手段】ワイヤ放電加工機用制御装置１０は、ワイヤ残寿命時間監視手段１１、放電加工時間算出手段１２、ワイヤ交換時期判定手段１３を有することにより、放電加工が中断するタイミングを認識し、そのタイミングに合わせて、プログラム運転の一時停止（プログラム運転停止指令手段１４），ワイヤ電極の切断（ワイヤ切断手段２０），ワイヤ交換手段２１によるワイヤ電極の自動交換を行え、ワイヤ電極の交換後には、ワイヤ電極の結線（ワイヤ結線手段２２）、プログラム運転の再開（プログラム運転再開指令手段１５）を行えるワイヤ放電加工機を制御する制御装置である。【選択図】図１
