本文介绍了机床ＣＡＤ工程数据库管理系统中ＢＯＭ处理器的设计和实施。该ＣＡＤ系统是为东北一个机床厂开发的项目，其中的工程数据库管理系统是在Ｉ－ＤＥＡＳ内部Ｐｅａｒｌ库的基础上开发的。全部工作扩充了Ｉ－ＤＥＡＳ的功能，对工程数据库的探讨和实际应用都具有一定的指导意义和应用价值。
This article introduces the design and implementation of the BOM processor in the machine tool CAD engineering database management system. The CAD system is a project developed for a machine tool plant in Northeast China. The project database management system was developed based on the I-DEAS internal Pearl library. All work has expanded the function of I-DEAS, and has certain guiding significance and application value to the exploration and practical application of engineering database.
