The rational and effective partition of the module has been the vital significance to the product design and manufacture. In this paper, a deficiency about the existing module partition can’t satisfy customer personalized is pointed out. Therefore, a method is put forward based on the design method of axiomatic, by analyzing the correlation among the parts, combining the dynamical clustering and mathematical statistic calculation to achieve the rough-to-fine division according to the principles of module partition. Finally, the based modules and the personalized modules are determined through the choice of based parameters and personalized parameters. The basic module and personalized module are integrated on a personalized product platform base on Internet. Customer can directly involved the product design by personalized product platform. The model was explained with example of the gantry grinding machine tool.
