This paper deals with process planning system based on machining process model. So far, the taxonomy of machining features, for example, hole, pocket, slot, etc. are shape based classsifications and it is difficult to assign the machining process information without competition of assignment rule. To solve this problem, the machining process modeling is needed for mapping between machined shape element and machining process. However, only tool behaviors are derived from giving the tool and the cutting motion to the machine tool. Therefore, the behavior model of cutting tool, working tool, to connect the machining operation and machined shapes are introduced. The working tool consists of the swept macro tool, the envelope of the swept macro tool, and the working edge. The feature model of the machining process, operating step, is also proposed from the viewpoint of a macro cutting tool, controled table motion, and enveloping constraints. To capture the essential information, the dimension of operating step and working tool are also proposed as the parameric representation of them.
