Research Initiation: A Fundamental Approach to the Integration of Dimensional Inspection into CAD/CAM

几何造型系统是任何以机械工程为基础的离散产品计算机辅助设计系统的基本构件。已经开发了许多这样的系统。然而，还不可能有效地使用它们来确定零件尺寸的公差。这个问题将分三个阶段解决。在第一阶段，将用数学术语定义公差。在第二阶段，将开发验证尺寸正确性的算法。在第三阶段，将进行实验，以证明确实可以验证公差，并且可以使用机器视觉检查来进行装配验证。

A geometric modeling system is a basic building block in any computer-aided design system for discrete products based on mechanical engineering. A number of such systems have been developed. However, it is not yet possible to use them effectively for establishing tolerances on dimensions of parts. This problem will be addressed in three phases. In the first phase, tolerances will be defined in mathematical terms. In the second phase, algorithms which verify dimensional correctness will be developed. In the third phase, experiments will be conducted to demonstrate that the tolerances can indeed be verified, and that verification for assembly can be performed using machine vision inspection.
