A synchronous powder feeding space and a laser processing method and apparatus for forming a three-dimensional

The present invention discloses a powder feeding synchronizing the three-dimensional space forming a laser processing method and apparatus according to the three-dimensional solid body and the head cladding simplified scanning up into several principle forming unit, each forming unit and then divided into several plies, using a single hollow annular laser beam airborne powder feeder, the powder feed nozzle to control the robot arm to drive a predetermined trajectory region and a boundary region filled plies in the scanning movement, in order to complete the entire cladding layer formed to sheet stacking unit forming the light . The apparatus comprises a powder-feeding the optical head, a laser generator, a manipulator, a control module, a transmission optical fiber, airborne powder feeder gas source, the control module each robot arm, the laser generator, airborne powder feeder connected to the light in the powder feeding nozzle can be fixed to the front end of a robot arm with a robot arm for spatial movement. The present invention can be implemented on any surface of the three-dimensional space and the accumulation of forming the cladding process can be performed drape, and other complex hollow structural member without support three-dimensional shaping zero.
