GB/T 16656.238-2013 Industrial automation systems and integration—Product data representation and exchange—Part 238:Application Protocol:Application interpreted model for computerized numeric controllers

Scope

This part of GB/T 16656 specifies the integrated resources necessary for the scope and information requirements of manufacturing using numerical control processing and related processes, including the scope and information requirements defined by the GB/T 19903 computer numerical controller data model.
[HT5”H][STFZ] Note 1: [HTSS][STBZ] The application activity model in Appendix F provides a graphical expression of the process flow and information flow, which form the basis for defining the scope of this part. [HT]
[HT5”H][STFZ] Note 2: [HTSS][STBZ][ZK（] This part is a member of the "STEP Manufacturing Suite" of the GB/T 16656 application protocol, which includes a large amount of information related to product manufacturing, such as the input of process planning (ISO 10303224［8］), the output of macro process planning (ISO 10303240［9］), numerical control processing (this part), casting (ISO 10303223［7］), and dimensional inspection (ISO 10303219［6］). Although each application protocol has unique scope elements, other elements are common to many application protocols, such as manufacturing features and manufacturing tolerance descriptions. [ZK）][HT]
This part is applicable to:
——manufactured mechanical parts;
——manufacturing process descriptions, including manufacturing processes, process steps, and related information defined by GB/T 19903;
[HT5”H][STFZ] Note 3: [HTSS][STBZ][ZK（] The GB/T 19903 standard covers milling, drilling, turning, and other processes, which were available when GB/T 19903.11—2008 and GB/T 19903.12—2008 were published. If additional GB/T 19903 descriptions are available, the next version of this part may include additional numerical control processes. [ZK）][HT]
——the current and future shapes of mechanical parts;
——manufacturing features of parts;
——manufacturing tolerances of parts;
——tool requirements for machining processes;
——tool paths for machining processes;
——GB/T 19
