Research on Deformation Control of Near-net-shape Blade
Based on the reverse segment deformation control method proposed previously,the blank machining allow-ances for traditional forward machining and reverse segment methods are explored.A deformation control strategy that com-bines both the forward and reverse segment method is proposed to address the issues of small machining allowances and high machining accuracy requirements for near-net-shape blades.Based on the forward and reverse segment machining processes,a grinding experiment of cast turbine blade is conducted,and the results show that the forward and reverse seg-ment machining processes can achieve high-precision machining of blades with small machining allowances,which has cer-tain advantages in the machining of near-net-shape blades.
