11、vedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which
12、a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matt
13、ers of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circul
14、ated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsib
15、le for identifying any or all such patent rights. ISO 14649-1 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and integration, Subcommittee SC 1, Physical device control. ISO 14649 consists of the following parts, under the general title Industrial automation systems an
16、d integration Physical device control Data model for computerized numerical controllers: NOTE Phase numbers below refer to the planned release phases of ISO 14649 which are described in Annex D.

18、s. ISO 14649-10 is the ISO 10303 Application Reference Model (ARM) for process-independent data. ISO 10303 ARMs for specific technologies are added after part 10. This part of ISO 14649 has a strong relationship to ISO 10303 AP238, which is a one-to-one 100 % mapping of ISO 14649, where ISO 14649 re
19、presents the ARM and AP238 the AIM. This relationship is referenced in this document and in other parts of ISO 14649. ISO 14649 is harmonized with ISO 10303 in the common field of Product Data over the whole life cycle. Figure D.1 shows the different fields of standardization between ISO 14649, ISO
20、10303 and CNC manufacturers with respect to implementation and software development. ISO 14649-1:2003(E) ISO 2003 All rights reserved vIntroduction Modern manufacturing enterprises are built from facilities spread around the globe, which contain equipment from hundreds of different manufacturers. Im
21、mense volumes of product information must be transferred between the various facilities and machines. Todays digital communications standards have solved the problem of reliably transferring information across global networks. For mechanical parts, the description of product data has been standardiz
22、ed by ISO 10303. This leads to the possibility of using standard data throughout the entire process chain in the manufacturing enterprise. Impediments to realizing this principle are the data formats used at the machine level. Most computer numerical control (CNC) machines are programmed in the ISO
23、6983 “G and M code” language. Programs are typically generated by computer-aided manufacturing (CAM) systems that use computer-aided design (CAD) information. However, ISO 6983 limits program portability for three reasons. First, the language focuses on programming the tool center path with respect
24、to machine axes, rather than the machining process with respect to the part. Second, the standard defines the syntax of program statements, but in most cases leaves the semantics ambiguous. Third, vendors usually supplement the language with extensions that are not covered in the limited scope of IS
