The invention relates to a method for introducing a perforation line into an airbag cover (1), wherein the airbag cover (1) is guided along an imaginary line (L) relative to a tool (2). In order to carry out the method, a machining beam (3.1) and a first measuring beam (4.1) are emitted and applied to a machining position (BO) on a light-facing side (6) of the airbag cover (1) facing the machining beam source (3), and a second measuring beam (5.1) is emitted and applied to a measuring position (MO) on a backlight side (7) of the airbag cover (1) facing away from the machining beam source. A first optical path (a) and a second optical path (b) are then determined and evaluated, wherein the first optical path (a) and the second optical path (b) are used to determine the remaining wall thickness (RWS). The processing beam source is controlled as a function of the determined remaining wall thickness (RWS).
本发明涉及一种向气囊盖(1)引入穿孔线的方法,其中使气囊盖(1)沿着假想线(L)相对于工具(2)导引。为了执行该方法,发射加工光束(3.1)和第一测量光束(4.1)施加到位于气囊盖(1)面向加工光束源(3)的向光侧(6)的加工位置(BO),并且发射第二测量光束(5.1)施加到位于气囊盖(1)背向加工光束源的背光侧(7)的测量位置(MO)。然后确定并评估第一光程(a)和第二光程(b),其中第一光程(a)和第二光程(b)用于确定剩余的余留壁厚(RWS)。根据所确定的余留壁厚(RWS)来控制加工光束源。
