| Research Abstract |
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.
