摘要： Provided is a wire electrical discharge machining device which has a tension controller for maintaining the tension of a traveling wire electrode at a tension. The tension controller includes: an allowed tension calculation module for determining an allowed tension that is less than a wire breaking tension at which the wire electrode breaks; and a set tension generation module for generating the set tension in accordance with the allowed tension. When the set tension is greater than the allowed tension, the set tension generation module reduces the set tension. When the set tension is less than the allowed tension, the set tension generation module increases the set tension in such a way that the set tension does not exceed the allowed tension.
