| 摘要: |
| 通过增加前倾角的前倾抛光工艺可降低表面粗糙度。探究前倾角对抛光表面质量的影响规律对提高整体叶盘叶片的抛光效率具有重要意义。通过砂布页轮前倾抛光实验,获得P400~P1200粒度砂布页轮抛光TC4整体叶盘叶片时,用在不同抛光次数、前倾角度下的表面粗糙度。实验结果表明,抛光表面粗糙度随着前倾角的增加呈下降趋势。分析了前倾角变化对抛光表面质量的影响机制,并从多个角度进行探讨。通过量化抛光效率,研究了各粒度砂布页轮抛光效率随前倾角的变化规律,并得到了最佳前倾角度;此基础上进行抛光效率最优的抛光工序规划,并通过抛光实验进行验证。实验结果表明,优化后的抛光工序规划能在较少工序内获得合格的表面粗糙度,验证了抛光工序规划结果的可靠性。该研究为TC4整体叶盘叶片砂布页轮抛光工艺的优化提供了理论依据和实践指导。 |

| Abstract: |
| The surface roughness can be reduced by increasing the forward-tilt angle of polishing process. It is of great significance to explore the influence law of the forward-tilt angle on the quality of the polished surface to improve the polishing efficiency of the blisk blade. In this paper, the surface roughness of the polished TC4 blisk blades polished by the belt flapwheel with a grain size of P400-P1200 under different polishing times and different forward-tilt angles was obtained through the forward-tilting polishing experiment. The experimental results show that the roughness of the polished surface decreases with the increase of the forward-tilt angle. Then the mechanism of the influence of the change of the forward-tilt angle on the quality of the polished surface was analyzed from multiple aspects. By quantifying the polishing efficiency, the variation law of the polishing efficiency of the belt flapwheel with various grain sizes with the forward-tilt angle was studied, and the optimal forward-tilt angle was obtained. On this basis, the polishing process planning with the optimal polishing efficiency was carried out, and verified by polishing experiments. The experimental results show that the optimized polishing process planning can obtain qualified surface roughness in fewer processes, which verifies the reliability of the polishing process planning results. This study provides a theoretical basis and practical guidance for the optimization of the belt flapwheel polishing process for TC4 blisk blades. |
