Aiming at the deformation controlling for compressor blades with volume damage

the birth and death finite element method was adopted to simulate the forming course of pulsed laser remanufacture. The dynamic deformation process and rules were got through the analysis. The pulsed laser forming process was optimized. The IPG optical fiber laser remanufacturing system was taken to experiment on the laser remanufacturing forming on impeller. The PowerScan Ⅱ blue light three dimensional reverse seeking measuring instrument was taken to measure the size of the remanufacturing forming deformation precisely. The conclusion of the finite element analysis was validated. The results show that

through the time increasing of the first and last two layers

the whole forming deformation is controlled within 1 mm; the deformation precision of heat-affected zone is controlled between 0.28~0.50 mm; the dimension precision after mechanical machining is within 0.02 mm; the angle precision is within 0.03°. The optimization of pulsed laser technology is verified. The process is taken reference for the remanufacturing forming of blade parts.
