SGER: A Geometric Search Engine Using CAD Data for Qualifying Contract Manufacturing: A Feasibility Study

该SGER的目标是探索基于网络的CAD搜索引擎的可行性，使设计师能够从全球分布的合同制造商池中有效地实时找到合格的合同制造前景。这将需要一个搜索系统，该系统将允许OEM公司通过编码CAD数据以及当前文本搜索来搜索并确定潜在承包商的资格，从而允许产品形状在数学上转换为可搜索的代码。探索性研究将确定将产品形状描述从实体建模理论表示的边界模型表示（B-Rep）转换为由场理论控制的边值问题的可行性。这些任务包括确定是否可以通过静电场分析来绘制机械产品形状的代码或“指纹”。为了在采购和生产计划方面对潜在的工业应用产生更广泛的影响，这种映射必须是一种有效和安全的CAD数据编码和分类方法

The goal of this SGER is to explore the feasibility of a web-based CAD search engine to allow the designer to efficiently find qualified prospects for contract manufacturing in real time from a pool of globally distributed contract manufacturers. This would require a search system that will allow OEM companies to search for and qualify potential contractors through coded CAD data in addition to current text searches, allowing product shape to be mathematically converted into searchable code. The exploratory research will determine the feasibility of converting the description of a product's shape from its Boundary Model Representation (B-Rep) as represented by the theory of solid modeling into a boundary value problem as governed by field theory. The tasks include determining if a code or "fingerprint" of a mechanical product shape can be mapped through electrostatic field analysis. In order to have significant broader impact on the potential industrial applications in purchasing and production planning, this mapping must be an efficient and secure method for CAD data coding and classification
