Abstract: It was difficult to realize effective integration of multi-source Numerical Control(NC)information due to its heterogeneous syntax structure and semantics. To deal with this problem, the Ontology of NC Information Resource(ONTO-NCIR)was established based on the characteristics of information forms in NC processing fields, and the semantic integration of NC information framework based on dynamic adaptation model was presented. Based on the establishment of NC information knowledge base, multi-source heterogeneous NC information was integrated in the syntax adaptation layer and the semantic adaptation layer. The process of NC information integration and the process of semantic mapping under dynamic adaptation mode were described. The implementation method of the eXtensible Markup Language(XML)syntax restriction rules and the semantic query model were proposed. Then, the establishment of independent adaptation channel and dynamic configuration of the restriction rules were described. Finally, the feasibility of the framework and its implementation method were verified by prototype analysis.
