<p>An interference prevention system of a machining head for preventing the interference between a punch head and a work holder and the interference between a laser head and the work holder in a compound machine for effecting punch-press machining and laser machining. A horizontal direction interference range, where the punch head and the laser head interfere with the work holder in the horizontal direction, and a vertical direction interference range, where the laser head interferes with the work holder in the vertical direction, are set, respectively. When laser machining is selected (S1) and the laser head lowers into the vertical direction interference range where it interferes with the work holder in the vertical direction (S2), the position of the laser head is monitored. When the laser head enters the horizontal direction interference range (S3), an alarm is raised (S4). On the other hand, when punch-press machining is selected, whether or not the punch head is about to enter the horizontal direction interference range where it interferes with the work holder in the horizontal direction is checked (S6). When the punch head is about to enter the horizontal direction interference range, punch-press machining is inhibited in advance and at the same time, an alarm is raised (S7).</p> |
