A controller for a wire electric discharge machine recognizes that a consumable, such as a filter, an electrode pin, and an ion exchange resin, has reached the end of its life and the timing at which discharge machining is interrupted, and temporarily stops programmed operation in accordance with the timing. Moreover, when receiving an evaluation result representing that time for exchange of the consumable has been reached, the controller instructs a consumable exchanging unit, such as a robot, to cause it to exchange the consumable for automatic exchange of the consumable. After the consumable has been exchanged, a programmed operation resumption instructing unit resumes the programmed operation. |
