1 Scope
This part of ISO 14649 specifies the process data which is generally needed for NC-programming within all
machining technologies. These data elements describe the interface between a computerised
numerical controller and the programming system (i.e. CAM system or shop-floor programming system). On the programming system, the programme
for the numerical controller is created. This programme includes geometric and technological
information. It can be described using this part of ISO 14649 together with the technology-specific parts (ISO 14649‑11, etc.). This part of ISO 14649 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 this part of ISO 14649 contains the definition of data types which are generally relevant for different
technologies (e.g. milling, turning, grinding). The features for non-milling technologies like turning, EDM , etc. will be introduced when the technology specific parts like ISO 14649‑12 for turning, ISO 14649‑13 for EDM , and ISO 14649‑14 for contour cutting of wood and glass are published. It includes the definition of
the workpiece, a feature catalogue containing features which might be referenced by several technologies, the general executables and the
basis for an operation definition. Not included in this schema are geometric items
and representations, which are referenced from ISO 10303's generic resources, and the technology-specific definitions, which are defined in
separate parts of ISO 14649.
