箱体零件的基于加工特征的方位描述法

Feature based Description for Box parts Information

以特征为基础，分解出了箱体零件的总体、面、孔、槽、孔系五大类三十六种加工特征，提出了一种新的箱体零件信息的描述方法——基于加工特征的方位描述法，并以此方法为基础，开发了箱体零件的信息描述与输入子系统。

In this paper, box parts have been divided into five groups with 36 machining features: over all ,plane, hole,groove and hole system on the basis of features. Then, a new description method ——the orientation method based on machining featrues for box parts is put forward. After that,in view of the method, a description system of box parts information has been implemented.
