Automating redesign of electro-mechanical artifacts presents many difficult problems to the developers of intelligent CAD systems. To address this need requires we identify new AI technologies for representation and planning and effectively apply them to the manufacturing problem. In this paper, we present the redesign problem and outline some of the critical points; presenting how to bring exi...

Multi-piece molding technology is an important tool in producing complex-shaped parts that cannot be made by traditional two-piece molds. However, designing multi-piece molds is also a time-consuming task. This paper proposes an approach for automatic recognition ofmold-piece regions and parting curves for free-form CAD models. Based on the geometric properties of objects and mathematical condi...

Feature-driven CAPP is the dominant model for Computer-Aided Process Planning today. Despite more than a decade of effort, there are no general methods for defining or identifying features, and consequently CAPP approaches in full generality could not been developed. An alternate to feature-driven CAPP is direct tool access-based models for process planning, which rely on the fundamental geomet...

-. In this paper, we propose a case study to compare the learning difference on a Computer added Drafting (CAD) course between traditional learning and e-learning. The learning materials for the e-learning were designed in Shareable

The research states home and abroad of the winnowing technology and winnowers are reviewed in brief. For the air duct, the core component of the winnower, the relevant technical parameters in the winnowing process are calculated based on the winnowing principle. The three-dimensional computer aided design (3D-CAD) software Solidworks is applied. The designed vertical winnower is able to separat...
