Abstract This paper describes the ideas and developments that lead to a new Computer Aided Process Planning (CAPP) approach : a blackboard-style, interactive CAPP system, in which the human process planner is assisted by expert modules, each capable of performing a process planning task. At all times, the human operator has full control over all planning activities. An important reasoning mechanism, that is inevitably linked with the interactive CAPP kernel, is opportunistic process planning. The implementation of this mechanism in an automatic feature based CAPP system will also be elaborated in this paper.

ISO 14649, known as STEP-NC, is new model of data transfer between CAD/CAM systems and CNC machines. In this paper, the modeling based on machining feature is proposed. The machining feature comes from the manufacturing process considering the restriction of machining technology and machining resource. Then the framework for computer aided process planning is presented, where the algorithms of operation planning is studied. The practical example has been provided and results indicate that machining feature based model can integrate with CAPP and STEP-NC seamlessly.
