A COLD-WORK METHOD

摘要

The invention relates to an ablation based cold work method, so that the method comprises ablating, along a predefined ablation path on an ablation target surface, to a predefined ablation depth by laser radiation having at least one characteristic wavelength and at least one pulse characteristic for each wavelength for the radiation to be used for ablation of said ablation target material, wherein the radiation from the source is directable via an optical path onto the working spot on said ablation target via a turbine scanner. The invention also relates to an ablation based cold work arrangement, so that the arrangement comprises a laser radiation source to provide the laser radiation be used in the ablation, and at least one turbine scanner arranged into the optical path arranged to lead laser radiation from said laser radiation source to the hit spot of the ablation target at the ablation path location. Such an arrangement can be used in manufacturing technology in automated systems, but also in weapon technology.
