Abstract

Product configuration technology is the core of the modular design of computer numerical control (CNC) machine tools. Combined with modular design technology and case-based reasoning (CBR) technology, this paper proposed a modular configuration design method based on CBR for CNC machine tools. Using the fuzzy similarity priority ratio and gray correlation analysis algorithm, respectively, the calculation of case priority and the case evaluation are realized and the best match case of the user needs is selected. The module configuration system was developed using MATLAB/gui. By designing the example and analyzing the result, the configuration system is more rapid and accurate than conventional methods in the process to find the best match instance.
