22、 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 a technical committee has been established has the right to be represented on that committee.
23、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 matters of electrotechnical standardization. International Standards are drafted in accordance wit
24、h 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 circulated to the member bodies for voting. Publication as an International Standard requires approv
25、al 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 responsible for identifying any or all such patent rights. ISO 6983-1 was prepared by Technical Committ
26、ee ISO/TC 184, Industrial Automation Systems And Integration, Subcommittee SC 1, Physical Device Control. This second edition cancels and replaces the first (1984), has been technically revised. This edition based on the text of the first edition with the following changes made: - the content has be
27、en restructured in a more logical order, - a combining of former parts 1 and 2; the commonly used G- and M-codes are merged in one part now, - the addition of the equal sign (=) to allow for axis indexing, - flexible programming methods with parameter calculation. ISO 6983 consists of the following

30、d address program format is described in this International Standard for machine control programs on perforated tape, magnetic media, or provided from a remote data source. The standards cover variable block format only and are not intended to specify machine design. Compliance with this internation
31、al Standard does not guarantee interchangeability of machine programs between machines. Annex A details some of the additional considerations necessary to ensure this interchangeability. The purpose of this revision of International Standard is: a) to consolidate the previous format standards into o
32、ne International Standard for positioning, line motion and contouring systems; b) to remove outmoded provisions of the previous International Standards, where feasible; c) to introduce format standards for new functions, not covered by previous International Standards; d) to reduce the difference in
33、 programming between different machine/control units; e) to provide guidelines for achieving program interchangeability between machines of similar capacity; f) to include the preparatory and miscellaneous codes.

35、positioning, line motion and contouring control systems used in the numerical control of machines. This International Standard helps the co-ordination of system design in order to minimize the variety of program manuscripts required, to promote uniformity of programming techniques, and to foster int
36、erchangeability of input programs between numerically controlled machines of the same classification by type, process, function, size and accuracy. It is intended that simple numerically controlled machines be programmed using a simple format, which is systematically extensible for more complex mach
37、ines. This International Standard is not intended for use in specialized case of numerically controlled flame cutting machines and drafting machines used specifically and exclusively in the shipbuilding industry. In this application a related format “the ESSI Format“ is specified in ISO 6582. 2 Norm

42、ram format The machine program shall be structured in blocks of data, which contain sets of commands to the control system. A block shall consist of a number of words each of which is a specific instruction to the control system. A character designated “end of block“ shall terminate every block of d
43、ata and in addition shall precede the first block of data. A “program start“ character shall precede all control data including “end of block“. It is recommended that it should be used as an “absolute rewind stop“ character. All alphabetic, numeric and special characters shall conform to annex B. Th
44、ose characters required for reproducing a hard copy of the machine program, listed in annex B as “non printing characters“ shall be ignored by the control equipment, with the exception of the LF/NL (end of block) character. If there is any group of characters that is not to be processed in accordanc
45、e with this part of ISO 6983, this group shall be within parenthesis characters (control out control in). Any such group shall not contain either: “:“ or “%“ characters. This group may be processed for display purposes, for example as instructions to an operator. Where it is necessary to identify a
46、machine program, this identification should be placed immediately after the program start character and before the first “end of block“ character. If the identification contains alpha characters, the entire identification should be enclosed with parentheses. If the program number is greater than the
47、 system can store or display, the least significant digits shall be displayed. It is recommended that the alignment code should be used at all positions in the program at which it is permissible to start the machine sequence. When used, this code shall be as defined in 6.4.1. The alignment function
48、character “:“ may be used as an intermediate rewind stop character. The “/“ (slash) character shall be used to provide an “optional block skip“ function validated at the option of the operator. When used, this character shall immediately precede the “sequence number“ word. A general classification of the format shall be used to detail the capabilities of a system and machine configuration. This is called the general format classification and is defined i
