Abstract

This paper is a new approach in developing a computer aided process planning expert system. A system model is designed and its competence is verified. The effort involved is limited to the manufacturing of rotational components using metal cutting operations, and generative process planning is chosen over variant-group technology-process planning. The process planning domain is analyzed in terms of the problem specifications and the knowledge characteristics. This analysis is used to classify the problem and the knowledge type according to the different expert system oriented classes. The model design is guided by tips provided for the different expert system classes, as well as relevant realizations from previous works, plus experimenting programming. A prototype system with a sample knowledge base is created as a result of this programming effort.

    Customized algorithms were used for automatic generation of NC program for turned components. Younis and Wahab (1997) framed a ES for axis symmetry parts using generative approach. The knowledge base model guided by different ES classes, realization from previous works and heuristic programming.
