Available online 19 April 2007. Abstract In this paper, a new approach has been developed to recognize the CAD models through their face adjacency relations and attributes and to automatically assemble the recognized parts in a CAD environment. Adjacent faces and the face attributes belonging to each face of parts designed in a CAD platform are derived by using of standard for the exchange of product data (STEP) file. They are represented in a square matrix format named face oriented relation matrix (FORM). An expert system was developed and embedded within the system. A knowledge base of the expert system is generated using a text editor. Reasoning the face adjacency relations and the face attributes in the knowledge base and FORM, the parts are recognized. Then, a reference face belonging to recognized parts is determined and they are positioned and assembled in assembly file through their reference faces. Part recognition approach developed in this study is applied to a computer aided assembly system. But it may be useful and practical for different CAD/CAM applications such as process planning and group technology too. The algorithm has been applied to a diesel automobile engine which has complex parts to demonstrate its efficiency and capability.

摘要
文中介绍了一种新的做法，已经形成以承认CAD模型，通过他们面对邻接关系和属性，并自动组装公认的零件在CAD环境。相邻的脸，面对属性，是属于每一个面对的部分设计在一来自个CAD平台导出用的交换标准产兴鱼持余会眼树兵值品数据（步骤）文件。他们是代表一个方阵格式命名面对面向关系矩阵（表格）。一个专家系统的开发和嵌入式系统内部。一个知识库的专家系统是利用一个文本编辑器。推理面对邻接关系的发展和面临的属性，在知识基础和形式，零件都得到了确认。然后，参考面属于公认的部分是取360问答决于他们所处的拼装起来，在大会通过的文件参细考面孔。部分识别赶反方法发达国家在这方面的研究应用到计算机辅助装配系统。但它可能是有用的和实际的做法不同的CAD/CAM应用，如工艺设计和成组技术。该方法已应用于柴油汽车发动机，其中有复杂的零件，以展示其效率及办事能力。
