12、. The work of developing International Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been authorized has the right to be represented on that committee. International organizations, governmental and non-governm
13、ental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 6582 was developed by Technical
14、 Committee ISO/TC 8, Shjobuilding and marine structures, and was circulated to the member bodies in August 1981. It has been approved by the member bodies of the following countries: Austria Italy Poland Belgium Japan Portugal Brazil Korea, Dem. P. Rep. of Romania Czechoslovakia Korea, Rep. of Spain
15、 Egypt, Arab Rep. of Mexico Sweden Germany, F.R. Netherlands United Kingdom India Norway USSR No member body expressed disapproval of the document. DIN IS0 6582 Seite 3 Shipbuilding - Numerical control of machines - ESSI format O Introduction “The ESSI format“ originally developed by the Central Ins
16、titute for Industrial Research (SI), Oslo, Norway, is widely used for NC drawing and flame cutting machines. It has also been adopted by other manufacturers of drawing machines, flame cutting machines and controllers. The technical progress of this equipment has led to an enlarged table of machine f
17、unctions, but the lack of coordination between the various manufacturers has resulted in different, incompatible “ESSI formats“ being adopted. Difficulties in data transfer and communication be- tween different users have been the result of these individual developments. In order to avoid faults in
18、the data transfer, the normal practice is to use the same physical control tape (paper tape, magnetic tape etc.) for both the NC drawing machine and the NC pro- duction machine. As the tape must contain the operational codes for both machines, care has to be taken to ensure that codes or machine fun
19、ctions not required for a particular machine will be ignored by its controller. As this problem also applies to control systems other than those using the “ESSI format“, it will not be covered by this International Standard. As communication and the interchange of data become more and more important
20、 in the future of shipbuilding, this Inter- national Standard will create a common basis for the control of those NC machine tools that use “ESSI format“. This International Standard will guarantee compatibility of pro- grams and controllers of different origin and lead to better com- munication bet
21、ween hardware manufacturers, program originators and users of numerical control (NC) machine tools. “The ESSI format“ may be used in connection with any data code for punched cards, punched tapes, magnetic tapes etc. Use of standardized data codes is however strongly recom- mended. Revisions of this
22、 International Standard will be proposed as technical progress warrants, or as future standards are adopted which conflict with this standard. Annexes A and B form integral parts of this International Stan- dard. 1 This International Standard specifies the ESSI format. It serves as a guide in the Co
23、-ordination of system design, to minimize the variety of programs required, to promote uniformity of pro- gramming techniques, and to foster interchangeability of pro- grams between NC drawings and flame cutting machines used in the shipbuilding industry.
