Abstract: At present, parametric design and feature modeling are the two main developing direction of CAD. Integrating feature modeling with parameterized technology is the effective method and measure to three-dimensional design and modeling, which product feature is modeled by parameter. According to it’s characteristic, common basic feature of shaft part is analyzed and feature of shaft part is classified and described concretely and feature information model is established in this study. Feature modeling method and parameterized feature modeling technology of shaft part are studied and parameterized feature modeling module based on UG NX for shaft part is developed. The results prove that the feasibility and effectiveness of this modeling technology and method.
