An Agent-based Sheet Metal Process Planning System

The requirements for computer-aided process planning (CAPP) systems have changed in the current integrated manufacturing environment. More requirements such as openness, real time operation and distribution of process planning need to be satisfied by integration. New systems must be open and dynamic with the ability to adapt and accept radical unpredictable changes in structures and industrial practices. This chapter proposes an agent-based process planning system (ABPPS) for optimal sheet metal PD. The structure of the system is discussed in detail. A number of agents are defined, including an unfolding agent, a feature recognition agent, a task agent, a nesting agent, a path planning agent, a bending agent, a machining method selection agent, a machine selection agent and a fixture/jig selection agent. Intermodules of typical agents (nesting agent, path planning agent, bending agent) are built for the system. In addition, how agents cooperate with others to implement tasks is also investigated.
