<p>PROBLEM TO BE SOLVED: To provide a laser trigger controller which corresponds to the speeding-up of the oscillation frequency of a laser. SOLUTION: The method and the device include a clock gate circuit 15 which gates the trigger signal of the laser beam, a sensor which detects a location which is irradiated with the laser beam, a control section which reads the location actually irradiated with the laser beam by the location signal from the sensor and calculates the location where the trigger signal is to be turned on from the read-in location where the laser beam is actually irradiated and a preliminarily given machining pattern data, and a comparator 16 which compares the location irradiated with the laser beam and detected by the sensor with the location where the calculated trigger signal output is turned on when a radiation means of the laser beam or a work begins to move, and outputs a signal when both locations coincide with each other. The controller calculates a location where the trigger signal output is to be subsequently turned off from the machining pattern data when the clock gate circuit is turned on by the above-mentioned outputted signal.</p> |
