ISO 14649-11:20 04规定了铣削工艺数据所需的特定于技术的数据元素。它与ISO 14649-10中描述的一般工艺数据一起描述了计算机化数字控制器和铣削编程系统（即CAM系统或车间编程系统）之间的接口。它可用于所有类型机器上的铣削操作，无论是铣床、加工中心还是带有能够铣削的电动工具的车床。ISO 14649-11:20 04的范围不包括任何其他技术，如车削、磨削或电火花加工。这些技术将在ISO 14649的其他部分中描述。 ISO 14649-11:20 04中描述的milling_schema的主题是表示铣削和钻孔加工过程的特定技术数据类型的定义。这包括自由曲面的铣削和棱柱形工件的铣削（也称为2 1/2维铣削）。 此架构中不包括以下内容: 几何项目；陈述；制造特点；可执行对象；所有技术通用的基类。 它们引用自ISO 10303的通用资源和ISO 14649-10。使用ISO 10303-11中定义的EXPRESS语言描述工艺数据。使用ISO 10303-21对数据进行编码。

ISO 14649-11:2004 specifies the technology-specific data elements needed as process data for milling. Together with the general process data described in ISO 14649-10, it describes the interface between a computerized numerical controller and the programming system (i.e. CAM system or shop floor programming system) for milling. It can be used for milling operations on all types of machines, be it milling machines, machining centres, or lathes with motorized tools capable of milling. The scope of ISO 14649-11:2004 does not include any other technologies, like turning, grinding, or EDM. These technologies will be described in further parts of ISO 14649. The subject of the milling_schema, which is described in ISO 14649-11:2004, is the definition of technology-specific data types representing the machining process for milling and drilling. This includes both milling of freeform surfaces and milling of prismatic workpieces (also known as 2 1/2-D milling). Not included in this schema are the following:

• geometric items;
• representations;
• manufacturing features;
• executable objects;
• base classes which are common for all technologies.

They are referenced from ISO 10303's generic resources and ISO 14649-10. The description of process data is done using the EXPRESS language as defined in ISO 10303-11. The encoding of the data is done using ISO 10303-21.
