The invention discloses a
laser-based inside-
laser coaxial wire-feeding additive manufacturing
system and a forming method. The
laser-based inside-laser coaxial wire-feeding additive manufacturing
system is formed by a laser, a wire feeder mechanism, a movement actuating mechanism, a
molten pool shape monitoring feedback module and a
system control module. After a part model is
cut into slices, aninitial path is planned, input parameters and technological parameters in a technology
database are compared, the
molten pool temperature corresponding to technological parameters and
input technology parameters under different feature structures is optimized, printing parameters and a
robot code under an optimal path are generated, a high-speed
infrared camera acquires
molten pool shape parameters during the printing process and transmits to the system control module, the system control module compares the acquired molten
pool shape data and the technology data of the technology
database module, meanwhile, the molten
pool temperature change is monitored, and the molten
pool temperature is corrected through feedback-adjusting laser power and is monitored and feedback-adjusted in real time, so that the molten pool shape is uniform and consistent and the printing process is stably controlled during the printing process.
