Description

【００２５】
次に図２により、被加工物６，７が同一材料の異なる厚みを有する一対の部分６，７からなる場合について述べる。図２において、被加工物のうち薄い部分６および厚い部分７が、図１（ａ）（ｂ）（ｃ）に示す吸収率の高い部分３および吸収率の低い部分４に各々対応して配置されている。図２において図１（ａ）（ｂ）（ｃ）に示す場合と同様、薄い部分６の表面はレーザ光１の焦点距離からずれ、厚い部分７の表面はレーザ光１の焦点距離に一致しているので、精度の良い突き合せ加工を行なうことができる。[0025]
Next, referring to Figure 2, a case will be described in which the workpiece 6, 7 is made up of a pair of portions 6, 7 of the same material but with different thicknesses. In Figure 2, the thin portion 6 and the thick portion 7 of the workpiece are arranged to correspond to the high absorption portion 3 and the low absorption portion 4 shown in Figures 1(a), (b), and (c), respectively. In Figure 2, as in the cases shown in Figures 1(a), (b), and (c) , the surface of the thin portion 6 is offset from the focal length of the laser beam 1, while the surface of the thick portion 7 is aligned with the focal length of the laser beam 1, thereby enabling accurate butt machining.
