| 为解决钛合金整体叶盘薄壁弯扭跨音速叶片叶型制造过程中存在的加工变形大、铣削稳定性差等问题，本文提出了一种整体叶盘加工预变形控制方法。采用叶型三维检测技术获取叶型位置度和扭转角，利用叶型铣削变形误差反向补偿方法控制叶片弯曲及扭转变形。在整体叶盘上进行了实验验证，结果表明该方法可有效提高叶型加工精度和成品合格率，具有技术借鉴价值。 |

| In order to solve the problems of large machining deformation and poor milling stability in the manufacturing process of thin-walled curved torsional transonic blade profile of titanium alloy blisk, a pre deformation control method for machining integral blisk is proposed in this paper. The position degree and twist angle of blade profile are obtained by 3D profile detection technology, and the bending and torsion deformation of blade are controlled by reverse compensation method of profile milling deformation error. The results show that the method can effectively improve the machining accuracy and the qualified rate of finished products. |
