针对大尺度产品三维模型坐标测量信息缺乏和面向任务坐标测量结果质量评价困难的问题，引入新一代产品几何量技术规范（GPS），提出了基于CATIA二次开发技术的坐标测量辅助设计方法，设计了CAD与CMM集成的XML数据结构，建立了坐标测量数据的UML模型；实现了符合新一代GPS要求的测量方案脚本化描述，开发了部分数据处理算法；提出了基于Monte Carlo方法的坐标测量不确定度评估方案和流程。基于以上技术开发了基于三维模型的大尺度坐标测量设计与评估系统并应用于飞机装配中的部件位姿测量，结果表明，设计的测量方案能够满足飞机柔性装配对接的要求，验证了上述方法的有效性。

To deal with the lack of information for coordinate measurement of three-dimensional model and the difficulty of quality evaluation of task-specific coordinate measuring results,the computer aided design method for coordinate measuring technology based on the secondary development of CATIA system was presented,according to the new gengration Geometrical Product Specifications (GPS).The XML data structure for integration of CAD and CMM was designed.The extended data model used UML technology for coordinate measurement was established.The scripted description of measurement process meeting the requirements of new generation of GPS was achieved.Some algorithms for measurement data processing were developed.And method and process of measurement uncertainty evaluation based on Monte Carlo simulation were proposed. Based on the above methods,the special software for three dimensional CAD-based computer aided design and assessment was developed and applied in pose measurement for assembly of aircraft parts.The results indicated that the measurement plan generated by the special software meets the requirements of part docking in aircraft flexible assembly,thus the effectiveness of the method was verified.
