Method for setting laser drilling machining condition and laser beam machine

To provide a method for setting a laser drilling machining condition and a laser beam machine which can alleviate the change of parameters requiring experience and skill and confirm the hole shape without separating a substrate and without manually inputting parameters of the optimum condition. Test regions are provided on at least five positions at the center and four corners of the machining region, a set of more than sixteen holes with different machining conditions is machined in each test region, and the optimum drilling machining condition is selected by comparing diameters, shapes and positions of the holes formed under the same machining condition in each test region with those of holes formed under other machining conditions. 本发明的目的是提供种激光开孔加工条件的设定方法以及激光加工机，前述激光开孔加工条件的设定方法以及激光加工机能够减轻需要经验和熟练度的参数变更，在不取下基板的情况下确认孔形状，无需手动输入最佳条件的各参数。本发明至少在前述加工区域的中心部、四角部的5个部位上设置试验区域，在各试验区域中加工不同加工条件的16个以上的孔的组，将各试验区域的在相同加工条件下形成孔的孔径、孔形状、孔位置与在其他加工条件下形成的孔的孔径、孔形状、孔位置相比较，选定最佳的开孔加工条件。
