针对现在定义的飞机结构件加工特征与加工操作不一一对应导致的特征排序存在大量空走刀问题，将加工特征分解为与加工操作一一对应的元特征。基于加工规则和最小耗费分支定界算法对元特征进行排序，实现刀具非切削行程最短。

The one-to-many mappings between the current deifned machining features and the machining operations lead to the increasing of the non-cutting path. In order to solve this problem, the machining features are de-composed into meta-features that are associated with a sin-gle machining operation individually. The rules abstracted from the machining process and the branch-and-bound algorithm are employed to sequence the meta-features to minimum the non-cutting path.
