摘要：挠性接头是精密导航系统的核心部件，其加工质量直接决定了导航的精度。而作为主要弹性感知部位的细筋结构，厚度为
40 µm，误差需要控制在 1 µm 以内，属于典型的微细加工技术。文章从挠性接头的加工方法出发，从细筋的刚度解析、仿真建模、
加工冷却系统、表面完整性控制和加工尺寸效应阐述细筋的加工研究现状和困难，以期为细筋的微细加工研究提供指导和启示。

Abstract: Flexible joint is the key component for precision navigation system. The machining quality of the flexible joint decides accuracy
of navigator. The thin rib is the main sensory structure, which has 40 µm with the 1 µm tolerance. The machining of the thin rib is the
typical micro-machining technology. Base on the machining technology of the flexible joint, the recent research study and diff iculty on
the rib stiffness analyze, simulation, cooling system, surface integrity, and size effect were presented, which can provide the guides and
inspiration for the thin rib machining in the future.
Keywords: flexible joint; thin rib; micro-machining
