材料、工具和工厂环境的不确定性以及人为干预，使变化成为任何组件制造过程中不可或缺的一部分。特别是，大体积的航空航天部件的组装是一个遇到显著程度的形状和尺寸变化的领域。当已知变化的来源和水平时，通常可以采取纠正措施来减少缺陷。对于未知的尺寸和形状变化，通常采用公差策略，以最大限度地减少与几何尺寸相关的生产不一致性的影响。这对相应的制造和装配过程的自动化产生了挑战性的问题。计量学正在成为一个主要的贡献者，能够预测，在真实的时间，自动装配问题有关的尺寸变化的零件和组件。这是通过持续测量尺寸和坐标点来实现的，重点关注产品的关键特性。在本文中，一些计量重点活动的大批量航空航天产品，包括其实施和应用的自动化制造和装配过程中，进行审查。这是通过在大体积飞机机翼结构的装配中使用案例研究方法来完成的。
Abstract Discrepancies of materials, tools, and factory environments, as well as human intervention, make variation an integral part of the manufacturing process of any component. In particular, the assembly of large volume, aerospace parts is an area where significant levels of form and dimensional variation are encountered. Corrective actions can usually be taken to reduce the defects, when the sources and levels of variation are known. For the unknown dimensional and form variations, a tolerancing strategy is typically put in place in order to minimize the effects of production inconsistencies related to geometric dimensions. This generates a challenging problem for the automation of the corresponding manufacturing and assembly processes. Metrology is becoming a major contributor to being able to predict, in real time, the automated assembly problems related to the dimensional variation of parts and assemblies. This is done by continuously measuring dimensions and coordinate points, focusing on the product's key characteristics. In this paper, a number of metrology focused activities for large-volume aerospace products, including their implementation and application in the automation of manufacturing and assembly processes, are reviewed. This is done by using a case study approach within the assembly of large-volume aircraft wing structures.
