Industrial automation systems and integration — Physical device control — Data model for computerized numerical controllers — Part 10: General process data

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
