This paper deals with the working tool model for process planning. We introduced the behavior model of cutting tool, working tool, as a feature models of machined shapes to connect the machining operation and machined shapes in previous reports. The working tool consists of the swept macro tool, the envelope of the swept macro tool, and the working edge. In this report, th egeometric representation of working tool is represented by its profile and path based on the geometric representation of Machining Features. Moreover, the process planning data model is proposed for representing the setup placement of the raw stock and the placement of the Working Step. We also introduce a removal volume that is the intersection between raw stock and Working Tool.
