LASER MARKING OF METAL MATERIALS MM （金属材料的激光打标毫米）.pdfVIP

LASER MARKING OF of workpiece in laser material interaction. For each configuration is the absorptivity given by combination of laser parameters – wavelength, METAL MATERIALS angle of incidence, polarization of the laser radiation and of the material radiative properties – state, geometry of the surface and temperature. The higher value of the resulting absorptivity means that the more laser 1 2 LYDIA SOBOTOVA , PETER DEMEC radiation is used for the processing [Sobotova 2014]. 1 Technical University in Kosice, Faculty of Mechanical Engineering, Department of Process and Environmental Engineering, Kosice, Slovakia 2Technical University in Kosice, Faculty of Mechanical Engineering, Department of Production Techniques, Kosice, Slovakia DOI: 10.17973/MMSJ.2015_12_201410 e-mail: Lydia.Sobotova@tuke.sk The contribution deals with the implementation of new information from the area of laser marking processing. The marking of various types of metal and non-metal materials are very actual topic of these days. The focus is on the production technical aspects of laser engraving and the introduction of processing strategies. Less attention F igure 2. The interaction of laser radiation with the workpiece material and is paid to the complex chemical process that can be observed when
