Formal Representation of Machining Process and Systematizing of Machining Feature Model

本文研究了单刃加工的加工操作和加工形状的特征模型，它们直接对应于加工过程模型。从宏观刀具的尺寸、进给运动的尺寸、包络约束的个数等角度提出了加工操作的特征模型。从去除量、加工表面和表面纹理的角度提出了加工形状的特征模型。两个特征模型之间的联系是由工作工具的概念完成的。工件由扫描宏刀具、扫描宏刀具的包络线和工作边组成。提出了加工过程的抽象模型和可表示线性方程的工序规划的抽象模型。我们还指出，只有15种加工操作。

This research deals with feature models of a machining operation and machined shapes for single cutting edge machining, which correspond directly to the machining process model. The feature model of the machining operation is proposed from the viewpoint of the dimension of a macro cutting tool, the dimension of feed motion, and the number of enveloping constraints. The feature model of the machined shape is also proposed from the viewpoint of the removal volume, the machined surface, and the surface texture. The linkage between both feature models is accomplished by the concept of a working tool. The working tool consists of the swept macro tool, the envelope of the swept macro tool, and the working edge. We proposed the abstract model of the machining process and the abstract model of operation planning which may represent the linear equations. We also pointed out that there are only 15 types of machining operations.
