Virtual engineering of mechanical components and systems has become the key enabling technology for modern production across all disciplines, and can no longer be viewed as a mere supporting activity. Virtual models themselves must be manufactured: designed, analyzed, inspected, exchanged, assembled, and maintained - virtually, in software - throughout the entire product life cycle. The premise of this proposal is that tolerancing and metrology of interchangeable virtual components are as important to the future of Virtual Engineering as interchangeability of mechanical components was critical for emergence of the modern mass production and manufacturing enterprise. The goals of this project are to create the new foundations for solid modeling that explicitly recognize the inherent inaccuracy of engineering data and limited resolution of geometric algorithms. The developed theory will provide formal foundations for tolerancing and metrology of virtual mechanical models, supported by systematic development of algorithms, and standardization of quality assurance practices. Successful outcomes of the proposed research will lead to improved theoretical foundations for modeling and representation of geometric information in engineering. It will also support revision of undergraduate and graduate teaching of geometric modeling and computer-aided design, and eventually may lead to creation of a new discipline.

机械零部件和系统的虚拟工程已成为所有学科现代生产的关键技术，不能再被视为仅仅是一种支持活动。虚拟模型本身必须在整个产品生命周期中进行制造：设计、分析、检查、交换、组装和维护-虚拟地，在软件中。 这个建议的前提是，公差和计量的可互换的虚拟组件是一样重要的虚拟工程的未来，机械部件的可互换性是现代大规模生产和制造企业的出现至关重要。该项目的目标是为实体建模创建新的基础，明确认识到工程数据的固有不准确性和几何算法的有限分辨率。所开发的理论将提供正式的基础，公差和计量的虚拟机械模型，支持系统开发的算法，和标准化的质量保证实践。 所提出的研究的成功成果将导致改进的理论基础，在工程中的几何信息的建模和表示。它还将支持修订几何建模和计算机辅助设计的本科生和研究生教学，并最终可能导致创建一个新的学科。
