AB  - The presented article deals with the technology and principals of laser cutting. The article describes the properties of CO2 laser beam, input parameters of laser cutting process, assist gases, the interaction of the cut material and the stability of laser cutting. The chemical compositions of cut materials and their influence on the cutting properties focusing on the roughness of the surface, are described as well. In the experimental part the roughness of the surface was measured by using the 3D scanning and evaluation of the microstructure in the HAZ area was provided.
