Abstract
本发明属于激光加工技术领域，公开了激光切割中切缝宽度的检测方法。该检测方法包括：在激光切割头进行切割时，实时获取激光切割头内气腔出气口处的第一出气气压值；根据喷嘴口径、激光切割头内气腔进气口处的进气气压值、喷嘴与工件之间的距离和工件待切割的切缝宽度获取对应的第一标定出气气压值和第一标定阈值；实时判断第一出气气压值与第一标定出气气压值差值的绝对值是否小于第一标定阈值，若是，则确定工件的切缝宽度符合使用要求。该检测方法能够在激光切割时实时判断切割宽度是否符合使用标准，检测效率高，避免出现不达标的切割宽度会影响工件的尺寸从而产生很多不良品的问题；自动化程度高，避免出现危害操作人员人身安全的问题。
