《GB/T 17645.42-2001工业自动化系统与集成 零件库 第42部分:描述方法学:构造零件族的方法学》由TC159(全国自动化系统与集成标准化技术委员会)归口,主管部门为中国机械工业联合会。
本标准规定了定义零件族及其零件属性的原则,用来完整地表示零件特性以及相关属性的特性。为了创建标准的标识层次结构,必须遵守本标准制定的规则和指南。供应商和用户应该把本标准中的这些规则作为建立层次结构的方法学。本标准范围如下:――将零件分类为通用族和简单族的规则;――对与零件族相关的适当特性进行选择的规则;――由库数据供应商提供的,用于描述零件族及其特性的属性。――用于字典数据交换的,EXPRESS信息模型中属性的规范。以下内容不在本标准范围之内:――具有聚合结构的装配零件库(等级3库);――零件自身的描述;――对某些可引用零件族的功能模型的描述;――对某些可引用零件族的表、程序库和文件的描述;――对管理零件库系统的描述;――用于库之间相互引用的EXPRESS资源构造。本标准中所规定的信息结构和方法学允许下列情况:――用字典给出的统一访问机制把来自不同库数据供应商的不同零件库在同一数据仓库中的集成;――用字典给出的统一访问机制把来自不同供应商的不同材料定义在同一数据仓库中的集成;――引用其他的假定在接收系统上可应用的供应商库;――当标准化层次结构存在时,则对其进行引用;――由终端用户对不地分类和检索层次所做的定义,以及把这些层次定义映射到在其系统中适用的供应商库。
Scope
This standard specifies the principles for defining part families and their part properties, which are used to fully represent the properties of parts and related properties. In order to create a standard identity hierarchy, the rules and guidelines set forth in this standard must be followed. Suppliers and users should use the rules in this standard as a methodology for establishing the hierarchy.
