Description / Abstract:

This part of ISO 10303 specifies the use of the integrated resources necessary for the scope and information requirements for manufacturing using numerical controlled machining and associated processes, including the scope and information requirements defined by the ISO 14649 data model for computerized numerical controllers.

NOTE 1 The application activity model in Annex F provides a graphical representation of the processes and information flows that are the basis for the definition of the scope of this part of ISO 10303.

NOTE 2 This part of ISO 10303 is a member of the "STEP Manufacturing Suite" of ISO 10303 application protocols, which cover a wide range of information associated with the manufacture of a product, such as the input to process planning (ISO 10303-224 [8]), the output from macro-process planning (ISO 10303-240 [9]), numerically-controlled machining (this part of ISO 10303), casting (ISO 10303-223 [7]) and the output from dimensional inspection (ISO 10303-219 [6]). While each application protocol has unique scope elements, other elements, such as manufacturing feature and manufacturing tolerance descriptions, are common to many of these application protocols.

The following are within the scope of this part of ISO 10303:

— mechanical parts for manufacturing;

— manufacturing process descriptions, including manufacturing operations, sequences of operations, and associated information as defined in ISO 14649;

NOTE 3 The ISO 14649 documents available at the time of publication cover milling, drilling, and turning processes (ISO 14649-11 and ISO 14649-12). Future editions of this part of ISO 10303 might include additional numerically-controlled processes if additional ISO 14649 descriptions become available.

— the AS-IS and TO-BE shapes of a mechanical part;

— manufacturing features of a part;

— manufacturing tolerance requirements of a part;

— tool requirements for machining operations;

— tool paths for machining operations;

— manufacture of mechanical products using manufacturing processes defined in ISO 14649;

— manufacturing product discipline view.

The following are outside the scope of this part of ISO 10303:

— composite material parts;

— description of manufacturing activities not related to automatic execution by a computerized numerical controller;

NOTE 4 This includes activities such as factory capacity planning and scheduling.

— a catalogue of machines available on a factory floor;

— a catalogue of tools available in a machine tool magazine;

— design features of a part;

— manufacturing preplanning activities;

— product discipline views other than manufacturing.
