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