本文件定义了如何设计工具项目的概念，仅限于任何类型的毛刺，以及相关属性和价值域的使用。 本文件规定了毛刺数据交换的简化3D模型要求。 以下内容不在本文件范围内: -可以存储或引用这些标准数据的应用程序； -为刀具创建和交换3D模型； -创建和交换切割物品的3D模型； -为本文件范围内未描述的其他工具项创建和交换3D模型； -为自适应项目创建和交换3D模型； -创建和交换装配项目和辅助项目的三维模型。

This document defines the concept of how to design tool items, limited to any kind of burrs, together with the usage of the related properties and domains of values. This document specifies the requirements of simplified 3D models for data exchange of burrs. The following are outside the scope of this document: — applications where these standard data can be stored or referenced; — creation and exchange of 3D models for cutting tools; — creation and exchange of 3D models for cutting items; — creation and exchange of 3D models for other tool items not described in the scope of this document; — creation and exchange of 3D models for adaptive items; — creation and exchange of 3D models for assembly items and auxiliary items.
