  • Aiming at the high precision in forming demand, the high difficulty in shape and deformation controlling and the low level of intelligence of the engineering application, the laser refabrication forming closed-loop controlling system was designed and implemented to achieve the goal of the thin-wall compressor blade forming with volume damage on the edge. The system obtained the closed loop monitoring of the dimension and deformation dimension, and on-line regulating the laser power. The laser refabrication forming experiment of thin-wall blade was conducted. The result showed that the shape recovery was full and on cracks existed in the surface. The system monitor precision for dimension could reach 1 mm. And the feedback loop and sampling frequency were up to 0.5 s and 2 Hz, respectively.
