Abstract: 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.

Abstract: A molded resin laminate in which the dimensional accuracy and the strength are excellent at a bent portion and a method for producing the same are provided. One, in which an average diameter of small cells existing in a region on a side of a resin cover to be formed into a surface layer is smaller than an average diameter of large cells existing in a region on a side of a base resin component to be formed into a base layer, is used as a foamed resin component to be formed into an intermediate layer of the molded resin laminate. After the base resin component is molded with a molding machine, the base resin component is held on a male mold of a forming machine different from the molding machine described above. A sheet-shaped laminate, which is obtained by joining the foamed resin component and the resin cover, is arranged between the base resin component and a female mold. Subsequently, the forming machine is subjected to mold clamping.

Abstract: A resin mold has a surface layer formed on the molding surface of a main body from a thermosetting resin and containing fine particles of silicon carbide. The surface layer can be formed simply by thermosetting the resin without calling for any plating, so that the mold can be made in a short time. The high hardness of silicon carbide gives a high wear resistance to the surface layer. The main body is formed from a thermosetting resin and contains metal particles.

Abstract: 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.
