航空航天市场竞争的加剧对航空航天制造商提出了降低成本、增加产品灵活性和提高制造效率的额外要求。在数字到物理尺寸验证领域以及如何在受不同环境条件影响的真实装配工厂中成功实现尺寸规格方面存在知识差距。本文介绍了一种新的验证设计（DfV）框架，用于低速率，高价值和复杂的制造业，以帮助实现高生产率的组装，通过有效的尺寸验证的大体积结构，在最终组装。“验证设计”框架的开发使工程师能够设计和规划大体积复杂结构的有效尺寸验证，以降低故障率和最终产品成本，提高过程完整性和效率，优化计量过程，减少工具冗余，提高产品质量和符合规范。的DfV方法的理论要素进行了概述，连同他们的测试使用工业案例研究的代表性的复杂性。工业测试证明，通过使用新的验证设计方法以及传统的“X设计”工具箱，改进了公差分析和综合，优化了大批量计量和装配工艺，并提高了工具和夹具设计的成本效益。
Increased competition in the aerospace market has placed additional demands on aerospace manufacturers to reduce costs, increase product flexibility and improve manufacturing efficiency. There is a knowledge gap within the sphere of digital to physical dimensional verification and on how to successfully achieve dimensional specifications within real-world assembly factories that are subject to varying environmental conditions. This paper describes a novel Design for Verification (DfV) framework to be used within low rate and high value and complexity manufacturing industries to aid in achieving high productivity in assembly via the effective dimensional verification of large volume structures, during final assembly. The ‘Design for Verification’ framework has been developed to enable engineers to design and plan the effective dimensional verification of large volume, complex structures in order to reduce failure rates and end-product costs, improve process integrity and efficiency, optimise metrology processes, decrease tooling redundancy and increase product quality and conformance to specification. The theoretical elements of the DfV methods are outlined, together with their testing using industrial case studies of representative complexity. The industrial tests have proven that by using the new Design for Verification methods alongside the traditional ‘Design for X’ toolbox, resulted in improved tolerance analysis and synthesis, optimized large volume metrology and assembly processes and more cost effective tool and jig design.
