在分析目前单柱式液压机CAD设计应用的基础上，提出引入实例推理原理和三维特征建模的参数化设计体系结构，应用特征建模技术建立模型，实现液压机主要结构的三维设计。%Based on the analysis of application situation of the design of hydraulic press, this paper presents the structure of hydraulic press system design with Case-based Reasoning principle and parametric design based on 3D feature modeling. The action of main function is also discussed. The models are established by using the technology of feature modeling, and the 3D design of hydraulic press is realized.
