It is generally agreed that higher level descriptions to refer to familiar features are needed to describe engineering components and machining operations, and one of the primary roles of features is the interface between design and process planning (or machining operation). The features are an abstraction idea from application viewpoints.For example, the Design feature is the shape abstraction from the designview, on the other hand, the Machining feature is one from the machining operation view.Especially the Machining feature is a very important idea for connecting the productmodel and it's mashining operations.This report deals with the machining features as follows :1) We introduce from shaping function as criterion for classification of machining feature in this research. This means that the machining feature should be a sufficient information model to the unit operation of process planning and operation planning.2) The classification of the Machining features from view point of shape aspect, machining operational spect, tool aspect and surface aspect is porposed.3) Precedence relationship which represents that one machining feature will precede another machining feature in the sequence of machining operations is considered in the developed CAM system.

人们普遍认为，描述工程部件和加工操作需要更高层次的描述，以引用熟悉的特征，特征的主要作用之一是设计和工艺计划(或加工操作)之间的接口。特征是从应用角度抽象出来的概念。例如，设计特征是对设计视图的形状抽象，而加工特征是从加工操作的角度进行的抽象。特别是加工特征是连接产品模型及其组合操作的一个非常重要的概念。本文对加工特征进行了如下研究：1)在本研究中，我们引入了形状函数作为加工特征的分类标准。2)从形状特征、加工操作特征、刀具特征和表面特征四个角度对加工特征进行分类。3)在所开发的CAM系统中，考虑了加工特征在加工操作序列中先于另一加工特征的优先关系。
