工业自动化系统和集成.机械装置控制.计算机数控器用数据模型.第10部分:通用过程数据

[中文适用范围]： ISO 14649 的这一部分规定了所有加工技术中数控编程通常需要的过程数据。这些数据元素描述了计算机化数控系统和编程系统（即 CAM 系统或车间编程系统）之间的接口。在编程系统上，创建数控系统的程序。该程序包括几何和技术信息。可以使用 ISO 14649 的这一部分和技术特定部分（ISO 14649-11 等）对其进行描述。ISO 14649 的这一部分提供了程序执行顺序的控制结构，主要是工作步骤和相关机器功能的顺序。ISO 14649 的这一部分中定义的“machining_schema”包含通常与不同技术（例如铣削、车削、磨削）相关的数据类型的定义。当 ISO 14649-12（车削）、ISO 14649-13（EDM）和 ISO 14649-14（木材和玻璃轮廓切割）等技术特定部分发布时，将引入车削、EDM 等非铣削技术的特征。它包括工件的定义、包含可能被多种技术引用的特征的特征目录、通用可执行文件和操作定义的基础。此方案不包括几何项目和表示（它们引用自 ISO 10303 的通用资源）以及技术特定定义（它们在 ISO 14649 的不同部分中定义）。ISO 14649 的这一部分不能独立存在。实施还需要至少一个技术特定部分（例如，ISO 14649-11（铣削）、ISO 14649-12（车削））。此外，该方案使用与 ISO 10303-224 和 ISO 10303-214 类似的加工特征。过程数据的描述采用 ISO 10303-11 中定义的 EXPRESS 语言。数据编码采用 ISO 10303-21。 [外文原描述]： ISO 14649-10:2004 specifies the process data which is generally needed for NC-machining and therefore common to several machining technologies. These data elements describe the interface between the programming system (i.e. CAM system or shop-floor programming system) and a computerized numerical controller. The programme for the numerical controller includes geometric and technological information. It can be described using ISO 14649-10:2004 together with the technology-specific parts (ISO 14649-11, ISO 14649-12, etc.). ISO 14649-10:2004 provides the control structures for the sequence of programme execution, mainly the sequence of working steps and associated machine functions. The "machining_schema" defined in ISO 14649-10:2004 contains the definition of data types which are generally relevant for different technologies (e.g. milling, turning, grinding). It includes: the general executables, including workplan, workingsteps and NC-functions; the definition of the workpiece; a feature catalogue containing features which might be referenced by several technologies; the basis for an operation definition. Not included in this schema are the following: geometric items; representations, which are referenced from ISO 10303's generic resources; the technology-specific definitions, which are defined in separate parts of ISO 14649. ISO 14649-10:2004 cannot stand alone. An implementation needs in addition at least one technology-specific part (e.g. ISO 14649-11 for milling, ISO 14649-12 for turning). Additionally, the schema uses machining features similar to ISO 10303-224 and ISO 10303-214. 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.
