Perforating machining method with laser beam |
摘要 |
Assuming that t1 represents a period of time until a detection signal is outputted after a sensor senses a laser beam passed through a through-hole of a workpiece, t2 represents a period of time until the detection signal derived from the sensor exceeds a preset threshold value, and t3 represents a period of time until radiation of the laser beam is actually stopped after the threshold value is exceeded, a total period of time (t1+t2+t3) of the periods of time t1 to t3 is set to be shorter than a time difference (T2-T3) between a pulse width (T3) and one cycle (T2) of a pulse signal for constructing a laser output command signal.
