This paper deals with an integrated modeling system of machine tools for dynamic analysis and simulation. The structural elements of the machine tools are represented by a set of primitives with information about finite element meshes. An algorithm is newly proposed based on a concept called CBC(Coded Box Cell) substitution approach to match the finite element meshes at the interface of primitives with relative movements. The nodes on the boundary surfaces between the two adjacent primitives are automatically adjusted by referring to the information of the vertex label and the face label of the meshes. The results of case study show that the finite element model is adjusted dynamically and locally at the boundary of the table and the slider which is fed on the table. It is expected that the method proposed is quite effective to analyze the structural characteristics of machine tools under the moving conditions.
