适用范围：This part of ISO 14649 specifies the process data which is generally needed for NC-programming within allmachining technologies. These data elements describe the interface between a computerised numericalcontroller and the programming system (i.e. CAM system or shop-floor programming system). On theprogramming system, the programme for the numerical controller is created. This programme includesgeometric and technological information. It can be described using this part of ISO 14649 together with thetechnology-specific parts (ISO 14649-11, etc.). This part of ISO 14649 provides the control structures for thesequence 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 aregenerally relevant for different technologies (e.g. milling, turning, grinding). The features for non-millingtechnologies like turning, EDM, etc. will be introduced when the technology specific parts like ISO 14649-12for turning, ISO 14649-13 for EDM, and ISO 14649-14 for contour cutting of wood and glass are published. Itincludes the definition of the workpiece, a feature catalogue containing features which might be referenced byseveral technologies, the general executables and the basis for an operation definition. Not included in thisschema 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.This part of ISO 14649 cannot stand alone. An implementation needs in addition at least one technologyspecificpart (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. Thedescription of process data is done using the EXPRESS language as defined in ISO 10303-11. The encodingof the data is done using ISO 10303-21.
