摘要： In a fixing structure and fixing method of a wire bobbin, the wire bobbin is abutted against the regulating member with the bolt inserted into the insertion hole of the wire bobbin. Then, a nut is inserted into a through hole while being kept inclined so that the axis of the through hole is substantially aligned with the axis of the bolt. Thereafter, the inclination of the nut is returned so that the axis of threaded hole becomes substantially aligned with the axis of the bolt, and then the nut is turned so as to insert part of a tapered portion into the insertion hole.

摘要： A controller for controlling a wire electric discharge machine is configured to monitor the remaining lifetime of a wire electrode and calculates an electric discharge machining time, thereby determining the timing of replacement of the wire electrode, so that it can recognize the timing of interruption of electric discharge machining. Consequently, a program operation can be suspended and the wire electrode can be cut and automatically replaced at that timing. After the replacement of the wire electrode, moreover, the wire electrode can be connected and the program operation can be restarted.
