In a laser cutting device and a cutting method disclosed in application No. CN201310644610.0, a laser emission module is used to emit a laser beam with a wavelength that is transmissive to a material to be processed. The laser beam formed by the beam combining module is converged to form multiple adjustable focal points on the optical axis. The laser cutting device provided by the present application has high processing precision and can meet the processing requirements of materials with large thickness.

[0003] However, during actual cutting, the metal in the heat-affected zone around the cutting point may be coarsened, oxidized or phase changed (such as the hardened layer of low-carbon steel), thereby causing the local hardness of the metal material to increase and the toughness to decrease, and the material may be easily cracked during subsequent processing (such as bending). In addition, the thermal expansion and contraction of the heat-affected zone may cause slight deformation of the material, which has a significant impact on thin and brittle materials (such as silicon steel sheets and glass), and it is difficult to meet the requirements of high-precision assembly. Moreover, the heat-affected zone may be accompanied by slag and oxide layer adhesion, which requires additional cleaning processes (such as grinding and pickling), thereby increasing the production cost.
