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.

摘要： A front face distance is obtained by measuring the position of a front face of an instrument panel held by an end effecter of a robot. An error on an optical axis, at the position of the front face is obtained based on the front face distance. Based on the error, the position of the instrument panel is adjusted so that a focal point of a laser meets the position at a predetermined depth defined with the front face as the standard. A back face of the instrument panel is irradiated with a laser to form a fine hole of a fragile section.
