Research Initiation: A Coupled Design-by-Features with Features Abstraction Approach for Simultaneous Product and Process Design

小行星9410359 目前研究的长期目标是开发一种 一种全新的计算机辅助几何设计方法， 将基于特征的设计方法与特征 从边界表示表面或实体模型中提取。 这项研究活动的重点是在一个设计的功能/循环环境中产生的功能的确定。 目前研究的基于特征的设计方法 使用称为环的抽象几何实体;要素 定义为循环。 一个设计师可以设计高- 例如肋或凸台的水平特征，随后，可以 通过修改回路修改特征。 循环为设计器提供了 灵活地产生创造性的设计，从而提供了一个 这是现有的按功能设计方法所缺乏的功能。 无论是按功能设计还是按循环设计， 不是故意创造的--是被创造出来的。 这些特征往往 影响可制造性、可组装性等问题。 通过一组循环映射（或特征 映射）。 这些映射的确定及其完备性 在这项研究中进行了研究。 计算机实现这些 映射由行业专家执行和验证。

9410359 Gadh The long-term goal of the current research is to develop a fundamentally new approach to computer-aided geometric design which integrates a features-based design approach with feature abstraction from boundary representation surface or solid models. The focus of this research activity is on the determination of features generated in a design-by-features/loops environment. The features-based design approach in the current research uses an abstract geometric entity called a loop; features are defined in terms of loops. A designer may design in terms of high- level features such as the rib or boss, and subsequently, may modify features by modifying loops. The loop provides the designer the flexibility to generate creative designs thus providing a function that is lacking in existing design-by-features approaches. Whether designing by features or by loops, new features - that are not intentionally created - get formed. These features often affect issues such as manufacturability, assemblability etc. These features are determined via a set of loop mappings (or feature mappings). Determination of these mappings and their completeness are studied in this research. A computer implementation of these mappings is performed and verified by industry experts.
