【摘要】：随着数字化设计与制造技术的快速发展,三坐标测量机(CMM)成为了企业产品零件检测与质量控制的重要手段,提高CMM的自动化与集成化是现代制造业信息化建设的关键。然而,在零件检测信息提取与管理方面,许多企业依然采用CAD中性文件作为信息的载体和基础,从而导致部分检测信息缺失、数据传递受阻等问题出现。MBD模型定义了产品检测过程中的完备信息,使得零件检测信息的提取与管理更加方便与直观,并为后续检测工艺规划等工作奠定了基础。本文首先分析了CMM的国内外理论研究与应用现状,找出其存在的缺点和不足。在实际调研的基础上,对基于MBD的零件检测信息提取与管理系统的结构进行了详细设计。其次,对零件MBD模型的检测信息进行了定义,明确了公差信息与几何特征信息之间关联关系,并构建了基于MBD的零件检测信息模型框架。在此基础上,利用Creo Parametric TOOLKIT二次开发工具,在Visual Studio 2010平台下开发了零件检测信息提取的应用程序。再次,研究了检测过程中的任务分配和路径规划问题。在检测任务分配方面,建立了符合军工企业车间实际的任务分配数学模型,利用遗传算法求解出了最优分配方式,并通过实例验证了模型的合理性以及算法的有效性。而对于检测路径规划,为将离散的检测点连接生成一条有效的无碰撞路径,提出基于遗传蚁群算法对检测路径进行优化。最后,结合上述分析与研究成果,利用Java、Oracle等技术,在Eclipse平台上开发了系统的原型系统,实现了CAD/CMM/MES集成。并通过企业试点运行,显著提高了企业检测效率,同时验证了其设计方法的可行性。
[Abstract]:With the rapid development of digital design and manufacturing technology, CMM (coordinate measuring Machine) has become an important means of product parts inspection and quality control. To improve the automation and integration of CMM is the key to the construction of modern manufacturing information. However, in part detection information extraction and management. Many enterprises still use CAD neutral files as the carrier and basis of information, which leads to partial detection of missing information. MBD model defines the complete information in the process of product inspection, which makes the extraction and management of part inspection information more convenient and intuitionistic. This paper first analyzes the current situation of theoretical research and application of CMM at home and abroad, finds out its shortcomings and shortcomings. On the basis of actual investigation. The structure of part detection information extraction and management system based on MBD is designed in detail. Secondly, the detection information of part MBD model is defined. The relationship between tolerance information and geometric feature information is clarified, and the framework of part detection information model based on MBD is constructed. The second development tool of Creo Parametric TOOLKIT is used. The application program of part detection information extraction is developed on the platform of Visual Studio 2010. The task assignment and path planning in the process of detection are studied. In the aspect of task allocation, a mathematical model of task assignment is established, which is in line with the actual situation in the workshop of military enterprises. The optimal allocation method is solved by genetic algorithm, and the rationality of the model and the validity of the algorithm are verified by an example. In order to link the discrete detection points to generate an effective collision free path, a genetic ant colony algorithm is proposed to optimize the detection path. Finally, combined with the above analysis and research results, using Java. The prototype system of the system is developed on the platform of Eclipse, and the CAD/CMM/MES integration is realized by the technology of Oracle. The efficiency of enterprise detection is improved significantly, and the feasibility of the design method is verified.
