| 摘 要： | 航空航天制造业中存在大量的铝合金装配孔加工需求。装配孔主要通过钻削加工实现，加工中存在铝合金出口毛刺过大的问题。出口毛刺直接影响工件的精度、抗疲劳强度、装配性能，去毛刺工序会极大地增加工时和成本。因此有必要对铝合金装配孔钻削出口毛刺进行研究，实现对出口毛刺的控制。从铝合金钻削出口毛刺的类型和测量方法、形成机理和高度预测以及毛刺控制方法等方面进行了系统性的论述，以期为铝合金钻削加工出口毛刺的研究提供帮助。

| Abstract: | There is a large demand for aluminum alloy assembly hole machining in aerospace manufacturing industry. The assembly hole is mainly realized by drilling, and there is a problem that the aluminum alloy exit burr is too large in the processing. The exit burr directly affects the accuracy, fatigue strength and assembly performance of the workpiece. The deburring process will greatly increase the man hour and cost. Therefore, it is necessary to study the exit burr of aluminum alloy assembly hole drilling to realize the control of exit burr. This paper systematically discusses the types, measurement methods, formation mechanism, height prediction and gross control methods of exit burr in aluminum alloy drilling, in order to provide help for the research of exit burr in aluminum alloy drilling. |
