摘要 |
<p>In order to detect a wire breakage as soon as possible, the wire electrical discharge machining apparatus includes a speed fluctuation compensator that generates a speed fluctuation suppression command that is a speed compensation value that suppresses fluctuation of the rotational speed of the tension motor on the basis of the rotational speed of the tension motor and a breakage detecting device that detects a breakage of the wire electrode on the basis of a comparison of a preset breakage detection threshold and a speed fluctuation suppression command output from the speed fluctuation compensator.</p> |
