The Research of Fundamental Enabled Technologies for KBE System in NC Programming

Aiming at the characteristics of the field knowledge of NC programming for complex components, the fundamental enabled technologies of the KBE system for NC programming have been researched . The knowledge repre sentation based on case and rule, the concept, approach and process of knowledge acquisition of the field knowledge of NC programming are briefly introduced. The application of CBR to NC programming for complex components is princi- pally expounded. The mode of the acquisition of the field knowledge of NC programming taking artificial knowledge acquisition as first machine learning as second and the inte- grated reasoning of CBR/RBR based on the control strategy with bidirectional and mixed reasoning are proposed. Research productions applied to the prototype system have been illustrated to be feasible.
