Effects of the laser beam interaction with the workpiece material

摘要

The laser beam machining uses the effects generated at the interaction of the workpiece surface with a laser beam that has adequate energetically and spatial - time characteristics. It is known that, as result of the laser beam interaction with the workpiece material, local chemical and physical effects are signalized. In order to study such effects and simultaneously the technological possibilities of laser beam equipment, some experimental researches were developed on an Ytterbium fiber laser equipment of 300 W. Movements of the laser spot along established trajectories were ensured, changing the distance between the trajectory segments. The influence of this distance on the obtained surface was highlighted.
