Research and development of knowledge base system in design of CNC machine tools

In order to establish a complete knowledge base to help designers accomplish the design of machine tools better and faster,based on the characteristics of CNC machine tool design knowledge,applying the object-oriented technique,realizing the representation of case knowledge and rule knowledge,the case base and the rule base were established.Meanwhile,the connection and management of each sub-knowledge bases were realized by applying meta knowledge.Under the environment of SQL Server 2000 and Visual Basic 6.0,the knowledge base management system was developed,which could realize knowledge acquiring,knowledge maintainability,knowledge inquiring effectively,and provide knowledge support for the design of CNC machine tools.At last,an application example was represented.
