Abstract:
The invention relates to an apparatus for surface processing on a workpiece, the apparatus comprising a positioning assembly (31) and a processing tool (4) comprising an active portion (8) configured to be directed to an impact position on a surface area of said workpiece and to operate on an impact area inside said surface area at the impact position. To meet high precision requirements and/or a good reproducibility of the processing, the apparatus further comprises an enclosure (21) for the workpiece, wherein the enclosure (21) comprises a wall section (25) adapted to be traversed by the active portion (8) and the positioning assembly (31) is configured to provide a movement of the enclosure (21) such that the position of said surface area with respect to the impact position of the active portion (8) is changed.
Abstract:
The invention relates to an apparatus for laser processing of a workpiece (81) on a three-dimensional surface area (82), the apparatus comprising a positioning assembly (31) and a laser assembly (4) to direct a laser beam (8) to an incidence position such that the laser beam (8) comprises a spot area (84) inside the surface area (82). The invention further relates to a corresponding method. To meet high precision requirements of the processing, the invention suggests a control unit configured to operate the incidence position along an incidence trajectory (83) on the surface area (82) and to provide a controlled energy density of the laser beam (8) along the incidence trajectory (83).
