【摘要】：随着数字化技术在制造业中的蓬勃发展,钣金零件的制造精度有了很大幅度的提高,这就对钣金零件的检验精度和检测效率体出了更高的要求。检测规划是对产品的检测步骤、检测方法、检测工具和尺寸公差等进行规划,是检测工作中尤为重要的一环。然而传统的检测规划方式已经很难跟上科技发展的脚步,所以需要一种新的数字化的检测规划方式来替代传统的检测规划方式。数字化检测规划技术是产品质量控制的关键环节,本文针对飞机钣金零件的特征,研究了基于全三维模型的检测规划系统的集成设计。抛弃了原来使用的VC6.0设计的检测规划系统,使用了C++在CAA、VS2005等工具进行开发,将本系统与CATIA集成,使他们成为一个整体。首先,介绍了在基于全三维模型的检测规划系统开发过程中所需的软件环境。其中包括对CATIA V5进行的简单介绍,所用CAA C++技术的原理和架构,同时介绍了钣金检测规划系统的总体框架的设计方法和实现方法。其次分别对钣金检测规划系统的子系统进行了详细的研究,即研究了交互式检测规划系统、智能专家检测规划系统和光电设备检测规划系统的工作原理、工作流程、实现方法进行了深入的研究。再次在每个子系统中增加了检测规划信息的三维表示模块,使整个系统实现了闭环设计。最后对钣金检测规划系统的集成设计和系统的初步测试进行了研究,包括系统的硬件集成、软件集成以及整个系统的初步测试结果。系统实现了基于三维模型的钣金零件的参数的提取人工交互检测规划、智能专家系统检测规划和光电设备检测规划等功能。本文的目的在于探索出一种数字化化检验规划技术,生成并发布检验报告,将结果反馈钣金零件检验部门。同时为钣金检验规划系统将存储模型、检验特征、检验规范、检验规则等信息数据化处理,构建出结构合理的数据库,定期对历史采集的数据进行统计更新,分析加工过程引起误差的原因,进一步为设计过程和加工工艺调整提供快速准确的数据支撑。
[Abstract]:With the rapid development of digital technology in manufacturing industry, the manufacturing accuracy of sheet metal parts has been greatly improved. This makes higher requirements for the inspection accuracy and efficiency of sheet metal parts. The detection planning is the planning of product detection steps, detection methods, inspection tools and dimensional tolerances, and so on. It is an important part of testing work. However, it is difficult to keep up with the pace of the development of science and technology in the traditional testing planning. Therefore, a new digital detection planning method is needed to replace the traditional test planning method. Digital detection planning technology is the key link of product quality control, this paper aims at the characteristics of aircraft sheet metal parts. The integrated design of detection planning system based on full-3D model is studied. The detection planning system designed by VC6.0 is abandoned and C is used in CAA. VS2005 and other tools to develop, the system and CATIA integration, so that they become a whole. First. This paper introduces the software environment needed in the development of the testing and planning system based on the full-3D model, including the brief introduction of CATIA V5, the principle and structure of the CAA C technology used. At the same time, the paper introduces the design method and implementation method of the overall framework of sheet metal detection planning system. Secondly, the subsystem of sheet metal detection planning system is studied in detail, that is, the interactive detection planning system is studied. Intelligent expert detection planning system and optoelectronic equipment detection planning system working principle and workflow. The implementation method is studied deeply. Thirdly, the 3D representation module of detection planning information is added in each subsystem. Finally, the integrated design of sheet metal detection planning system and the preliminary test of the system are studied, including the hardware integration of the system. Software integration and the preliminary test results of the whole system. The system realizes the extraction of parameters of sheet metal parts based on 3D model and manual interactive detection planning. The purpose of this paper is to explore a digital test planning technology to generate and publish inspection reports. The results are fed back to the sheet metal parts inspection department. At the same time, the storage model, inspection features, inspection specifications, inspection rules and other information are digitized for the sheet metal inspection planning system, and a reasonable structure database is constructed. The data collected from history are updated regularly to analyze the causes of errors caused by machining process and to provide fast and accurate data support for the design process and process adjustment.
