Correlation between laser finishing technological parameters and materials absorption capacity

The paper deals with some preliminary theoretical and experimental researches concerning different types of metallic materials polishing through laser beam machining (LBM). The specific mechanism of material removal process presents an apparently simple process. In details, this new technology is very difficult to be applied in order to achieve the required smoothening of machined surface due to the multitude of interfering factors concerning material characteristics and surface microgeometry to be machined. These centry data have to be correlated with technological parameters, which basically contribute to the energy density brought on the surface of machined surface. The paper emphasises the high potential of the LBM finishing technology, which has the capacity to obtain a nanometric level of surface roughness (Ra) under conditions of computer aided machining.
