| 摘要: |
| 为减轻小孔径高温合金蜂窝侧铣后蜂窝孔的堵塞程度,首先提出了一种基于图像识别的加工质量表征方法；其次通过单因素方法探究了主轴转速n、每齿进给量fz、切削深度ap对蜂窝孔堵塞程度的影响,并通过响应曲面法建立了工艺参数与蜂窝孔面积之间的函数关系,进行了方差分析以评估所建立的数学模型,结果表明,最优的铣削工艺参数组合为主轴转速7 528 r/min、每齿进给量0.021 mm、切削深度0.2 mm,相较于未优化的铣削参数条件下蜂窝孔的面积提高了15.9%；最后采用冰填充方法进行辅助加工,针对本文所研究的航空涡轮发动机定子密封环组件设计了一款冰填充夹具,进行铣削加工实验证明了其可行性,进一步将蜂窝孔铣削后的面积提高了8.4%。所阐明的工艺参数作用机制和获取的工艺参数优化结果可以用于指导实际生产,同时,冰填充方法为其他类型的蜂窝加工提供了参考。 |

| Abstract: |
| To reduce the clogging of small aperture high-temperature alloy honeycomb hole after side milling, a method based on image recognition is first proposed to characterize the machining quality. Then, the effects of spindle speed (n), feed per tooth (fz), and cutting depth (ap) on the clogging degree of the honeycomb pore are investigated using a single-factor approach. A functional relationship between the process parameters and the honeycomb cell area is established through response surface methodology, followed by variance analysis to evaluate the model. The optimal milling parameters were found to be a spindle speed of 7 528 r/min, feed per tooth of 0.021 mm, and cutting depth of 0.2 mm, which increased the honeycomb cell area by 15.9% compared to unoptimized parameters. Finally, the ice filling method is used for auxiliary processing, and a corresponding fixture for the stator sealing ring assembly of an aero turbine engine is designed. Milling experiments verify its feasibility, and the honeycomb pore area is further increased by 8.4%. The elucidated mechanism of process parameters and the results obtain from the optimization of process parameters can be used to guide actual production, while the ice filling method provides a reference for other types of honeycomb processing. |
