A laser forming system with a plenum and gas supply ; a method using such laser forming system

摘要

A laser forming apparatus (10) includes a motion system (14). A mounting fixture (22) is affixed to the motion system (14) for supporting a workpiece (12). A plenum (24) is affixed to the fixture (22) for surrounding the workpiece (12) . A gas supply (36) is joined in flow communication with the plenum (24) for channeling thereto an inert gas under pressure to fill the plenum (24). A laser (26) is aligned with the plenum (24) for projecting a laser beam (28) at the workpiece (12) inside the portable plenum (24).
