An integrated artificial intelligent computer aided process planning system

摘要

This paper presents an integrated artificial intelligent (IAI) system for dynamic computer-aided process planning (CAPP). The system, IM-CAPP, integrates fuzzy logic (FL) and artificial neural networks (ANN) to perform the dynamic recognition and adaptive-learning tasks of the workpieces and process plans. Also, it adopts the idea of important (critical) feature concept for evaluating the suitability of existing process plans for incoming product designs. In addition, the technique of expert system (ES) is utilized. The system combines variant and generative CAPP and is capable of generating plans that are suitable for workpieces that either are similar to existing workpieces or new. The proposed system described has been realized on a computer prototype program. An illustrative example is also provided.
