9805907 Wang Deformed swept volumes are defined as the volumes swept by deforming objects undergoing general motions. Development of fast and accurate sweep generators, which can represent and analyze swept volumes generated by general three-dimensional objects undergoing general motions, has been an important research area in solid modeling and computer-aided design and manufacturing technology. Research on swept volume has potential for advancing existing manufacturing technologies, thereby resulting in an increase of manufacturing productivity, product quality and cost reduction. The objective of this POWRE project is to develop a new theoretical framework for the representation and analysis of deformed swept volumes. This analysis will greatly expand the range of application of the deformed swept volume approach to computer-aided design and manufacturing and will establish the P.I. as a significant contributor to this field. The recently developed sweep differential equation approach for rigid objects will be modified and used for the first time to represent, compute, and analyze the swept volumes of deformed 3D objects. Advanced computer programming tools will be utilized to design graphical user interfaces and develop computer software for the visualization and integration with commercial software. This technique will be used to construct modules used in the computer-aided design software and then applied to the computer-based dynamic NC (Numerically Controlled) simulation and verification. This work will be of interest and value to industry, once the fundamental issues are successfully addressed.

9805907 Wang变形扫描体积被定义为通过使经历一般运动的对象变形而扫描的体积。快速、准确的扫描生成器是实体造型和计算机辅助设计与制造技术中的一个重要研究领域，它能够快速、准确地表示和分析一般三维物体在运动过程中生成的扫描体。对扫描体积的研究具有推进现有制造技术的潜力，从而导致制造生产率的提高，产品质量和成本的降低。这个POWRE项目的目标是开发一个新的理论框架的表示和变形扫描体的分析。这一分析将大大扩展变形扫描体方法在计算机辅助设计和制造中的应用范围，并将建立P.I.为这个领域做出了重大贡献最近开发的扫描微分方程方法的刚性物体将被修改，并用于第一次表示，计算和分析变形的三维物体的扫描体积。将利用先进的计算机程序设计工具设计图形用户界面，开发计算机软件，使之可视化并与商业软件相结合。 该技术将被用于构建计算机辅助设计软件中的模块，然后应用于基于计算机的动态数控仿真和验证。一旦基本问题得到成功解决，这项工作将对工业界产生兴趣和价值。
