Laser machining of chosen materials

Abstract

A paper deals with technological applications of laser. It evaluates the influence of design and technological conditions on output parameters of cutting process and also presents relative laser machinability of polymeric and metallic materials; in addition, it shows possible evaluation of structural change of metals and it gives mathematical model for determination laser cutting quality functions based on results of the experimental research. The temperature distribution has been derived. Results of plastic materials and hard-to-machining metals machinability are shown. Finally, surface quality evaluation after exposure to concentrated light energy and quantification of material microhardness are described.
