| 摘 要： | 对零件库进行了介绍，主要研究了临时数据库(TDB)的功能，提出了在FORTRAN语言联编和UG／GRIP语言映射过程中，运用组结构实现TDB的功能，其具体操作是运用链表来实现对临时几何实体的操作，即实现临时几何实体的删除、组实体的转化等操作；将符合ISO13584．31标准的FORTRAN联编程序文件，通过用C语言编写的转换接口的编译，最终生成Unigraphics系统下的GRIP语言程序．

| Abstract: | This paper introduces the Parts Library,mainly studies the function of temporary database(TDB),and gives an implimentation method using group structure which can achieve the function of TDB during mapping of FORTRAN language binding to UG/GRIP program language.The material operation is to impliment operations of temporary geometrical entities using chain tables,then realize operations that temporary entities are deleted and group entities are changed. FORTRAN language binding program files,according to ISO 13584.31 are turned into UG/GRIP programming language using translation and editing of C program language. |
