12、ndards 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 a technical committee has been established has the right to be represented on that committee. International or
13、ganizations, 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 matters of electrotechnical standardization. International Standards are drafted in accordance with the rules give
14、n 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 circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 7
15、5 % 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 responsible for identifying any or all such patent rights. ISO 14649-111 was prepared by Technical Committee ISO/TC 184

18、achine tool data model for general manufacturing processes is to form the subject of a future Part 110. Gaps in the numbering were left to allow further additions. ISO 14649-10 is the ISO 10303 application reference model (ARM) for process-independent data. ISO 10303 ARMs for specific technologies a
19、re added after Part 10. ISO 14649 is harmonized with ISO 10303 in the common field of product data over the whole life cycle. ISO 14649-1:2003, Figure 1, shows the different fields of standardization between ISO 14649, ISO 10303 and CNC manufacturers with respect to implementation and software devel
20、opment. ISO 14649-111:2010(E) ISO 2010 All rights reserved vIntroduction Modern manufacturing enterprises are built from facilities spread around the globe, which contain equipment from hundreds of different manufacturers. Immense volumes of product information will be transferred between the variou
21、s 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 standardized by ISO 10303. This leads to the possibility of using standard data throu
22、ghout 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 6983 “G and M code” language. Programs are typically generated by computer-
23、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 centre path with respect to machine axes, rather than the machining process with respect to the part
24、. Second, ISO 6983 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 ISO 6983. ISO 14649 is a new model of data transfer between CAD/CAM systems and C
25、NC machines, which replaces ISO 6983. It remedies the shortcomings of ISO 6983 by specifying machining processes rather than machine tool motion, using the object-oriented concept of Workingsteps. Workingsteps correspond to high-level machining features and associated process parameters. CNCs are re
26、sponsible for translating Workingsteps to axis motion and tool operation. A major benefit of ISO 14649 is its use of existing data models from ISO 10303. As ISO 14649 provides a comprehensive model of the manufacturing process, it can also be used as the basis for a bi- and multi-directional data ex
27、change between all other information technology systems. ISO 14649 represents an object-oriented, information- and context-preserving approach for NC (numerical control) programming that supersedes data reduction to simple switching instructions or linear and circular movements. As it is object- and
28、 feature-oriented and describes the machining operations executed on the workpiece, and not machine-dependent axis motions, it will be run on different machine tools or controllers. This compatibility will spare all data adaptations by postprocessors, if the new data model is correctly implemented o
29、n the NC controllers. If old NC programs in ISO 6983 are to be used on such controllers, it is necessary that the corresponding interpreters be able to process the different NC program types in parallel. ISO TC 184/SC 1/WG 7 envisions a gradual evolution from ISO 6983 programming to portable feature
30、-based programming. Early adopters of ISO 14649 will certainly support data input of legacy “G and M codes” manually or through programs, just as modern controllers support both command-line interfaces and graphical user interfaces. This will likely be made easier as open-architecture controllers be
31、come more prevalent. Therefore, ISO 14649 does not include legacy program statements, which would otherwise dilute the effectiveness of ISO 14649.

32、el for computerized numerical controllers Part 111: Tools for milling machines 1 Scope This part of ISO 14649 specifies the data elements describing cutting tool data for milling machine tools and machining centres, which work together with the process data for milling machine tools and machining ce
33、ntres specified in ISO 14649-11. They can be used as criteria for selecting one of several operations; they do not describe complete information on a particular tool. Therefore, leaving out optional attributes gives the controller more freedom to select from a larger set of tools. NOTE 1 The numeric
34、al control (NC) is assumed to have access to complete description of specific tools in a database. The milling_machine_tool_schema defined in this part of ISO 14649 serves as a basic tool schema, including the information required by the CNC to select a tool from the machine tools tool magazine. NOT
35、E 2 In ISO 6983, the tool is defined by its identifier (e.g. “T8”). No further information concerning the tool type or geometry is given. This information is part of the tool set-up sheet, which is supplied with the NC program to the machine. The tool set-up sheet gives the relationship between the
36、tool location (e.g. “slot 8 of the tool magazine”) and the type of tool (e.g. “drill 4 mm”). This part of ISO 14649 also specifies the information to be provided in the tool set-up sheet: tool identifier; tool type; tool geometry; application-dependent expected tool life. The milling_machine_tool_sc
37、hema does not include information which is part of the tool database. The tool database is related to the machine tool and the tool itself, but is independent of the NC program. The following data types are outside the scope of this part of ISO 14649: normative tool life; tool location in the tool c
38、hanger; adaptive items also know as tool holders or tool clamping devices; tools for other technologies, such as turning, grinding and electrical discharge machining (EDM) 1) . 1) These technologies are described in other parts of ISO 14649.

39、 It is important to understand that all length measure types used in this part of ISO 14649 are not toleranced length measure types because they are used to describe the tools required for the manufacturing of a workpiece, not the actual dimensions of the tools available at the machine. A real tool
40、will be selected by the tool management based on the actual tool dimensions and the tolerances of features. This part of ISO 14649 uses the EXPRESS language as specified in ISO 10303-11. 2 Normative references The following referenced documents are indispensable for the application of this document.
