摘要： PROBLEM TO BE SOLVED: To discriminate exact replacement timing by discriminating the replacement timing of a movable cutting edge and a fixed cutting edge in a cutting mechanism part not only from time but also from the consumed degree of the cutting edges.
SOLUTION: A consumption rate storage means is provided for storing a consumption rate (1/P) per one cutting of the cutting edge of a wire cutting device for every wire diameter and material. Cutting frequency during machining is obtained from the time from the start of machining to the end and the frequency of cutting operation per unit time (S21-S24). A value obtained by multiplying the cutting frequency by the consumption rate (1/P) of a used wire is added to an accumulated consumption rate R up to the present to update the accumulated consumption rate R (S25). When the accumulated consumption rate R exceeds a predetermined consumption rate, the replacement of a tip (the cutting edge) is urged, and when the tip is replaced, the accumulated consumption rate R is cleared. Also when an alarm of wire cutting failure is outputted (S22), the tip is replaced, and the accumulated consumption rate R is cleared. Further, the consumption rate (1/P) stored according to the achievement of cutting can be changed.

摘要： PROBLEM TO BE SOLVED: To prevent a wire electrode from departing from a wire traveling path using a simple configuration.
SOLUTION: A wire bobbin 2 is driven in the reverse direction of a wire feed direction by a torque motor 3 to apply tension to the wire electrode 1, and a velocity detector 4 that detects a rotation velocity of the wire bobbin 2 is provided. The wire electrode 1 is laid along the wire traveling path that includes a guide roller 14, a brake roller 5, upper and lower guides 8 and 9, and wire take-up rollers 10a and 10b. When the velocity detected by the velocity detector 4 meets or exceeds a predetermined velocity, the output torque of the torque motor 3 is increased so that an inertial force of the wire bobbin 2 causes the wire electrode 1 to be slackened, thus preventing the wire electrode 1 from departing from the wire traveling path. Only the provision of the velocity detector 4 can easily prevent the wire electrode 1 from departing from the wire traveling path, and the work of laying the wire is made easy.

摘要： PROBLEM TO BE SOLVED: To prevent a wire electrode from being broken during the preparation operations before electric discharge machining.
SOLUTION: When a wire electrode is arranged along a traveling path by manual operation, a motor M1 for feeding the wire electrode to a workpiece is driven in response to a predetermined torque command from a control section 30 with a switch SW1 on a side a. The wire electrode is prevented from being broken by facilitating the manual operation. The wire electrode is connected, and a motor M2 for delivering the wire electrode from the workpiece is driven at a predetermined speed, whereby the electrode is run. Then, the switch SW1 is shifted to a side b and a switch SW2 to the side a, and the motor M1 is subjected to torque control such that a tension on the wire electrode detected by a tension detector 6 is equal to a command tension. When a variation of the tension on the wire electrode is converged, the switches SW1 and SW2 are shifted to the side b, speed control of the motor M1 is performed so that detected tension is equal to the command tension, and electric discharge machining is started. Though the tension on the wire electrode is varied due to static frictional force during the start of running of the wire, the wire electrode can be prevented from being broken by the torque control of the motor M1.
