The invention relates to the technical field of laser metal cutting, in particular to a laser metal cutting method and system. The method comprises the following steps: acquiring a first matching rate corresponding to an upper boundary and a second matching rate corresponding to a lower boundary according to a section of a metal element cut by laser, acquiring characteristics of each part of a section area according to a relationship among the first matching rate, the second matching rate and a preset threshold, and acquiring an adjusting weight according to the characteristics of each part, and the laser cutting parameters are adjusted according to the adjusting weight, and the metal element is cut according to the adjusted laser cutting parameters. By means of the laser cutting method and device, the efficiency of the laser cutting process and the laser cutting effect are improved. 本公开涉及激光金属切割技术领域，具体涉及一种激光金属切割方法及系统。方法包括：根据金属元件被激光切割后的切面，获取上边界对应的第一匹配率和下边界对应的第二匹配率，根据第一匹配率、第二匹配率与预设门限的关系，获取切面区域各部分的特征，根据各部分的特征获得调
