摘要：NOMEX蜂窝芯薄壁、铺层的复杂结构使其切削性能差和易撕裂，而现有顺铣方法不能解决切割后纸基蜂窝芯的边缘分层、起毛、薄边铣缺等问题。本文分析了纸蜂窝的破坏模式、纸蜂窝芯的压缩破坏过程及破坏机理，提出了非常规的逆向旋转加工薄壁纸基蜂窝芯型面的方法，并通过试验验证了该方法的可行性。

Abstract:The structural complexity of the thin wall and laminate of the NOMEX honeycomb core makes it difficult to cut and easy to tear.The existing milling technology can not solve the problems of edge delamination，fuzziness and thin end notching of paper honeycomb cores after cutting.The failure mode and related mechanism of the paper honeycomb and the core are analyzed，an unconventional method of reverse rotation machining of the shaped profile of the thinwalled paper honeycomb core is also proposed and verified by experiment.
