11、:2012(E)ForewordISO (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 wh
12、ich 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
13、matters 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 circ
14、ulated 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 responsi
15、ble for identifying any or all such patent rights.ISO 5608 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 9, Tools with cutting edges made of hard cutting materials.This fourth edition cancels and replaces the third edition (ISO 5608:1995), which has been technically rev

18、serts, thus simplifying orders and specifications for such tools.The designation of boring bars (tool holders with cylindrical shank) is given in ISO 5609-1. 2 Explanation of the designation code2.1 GeneralThe designation code comprises 10 symbols for the designation of dimensions and other characte
19、ristics of the tool and the insert, of which the first nine symbols shall be used in any designation. The last symbol may be used where necessary.In addition to the standardized designation symbols in positions (1) to (10), a supplementary symbol consisting of a maximum of three letters and/or numbe
20、rs may be added by the manufacturer for a better description of his/her products, on condition that this symbol is separated from the standardized designation by a dash and that it does not contain letters specified for position (10).No addition to, or extension of, the code specified in this Intern
21、ational Standard shall be made without consulting and securing the agreement of ISO/TC 29. Rather than adding symbols not provided for in this system, it is preferable to add to the designation conforming with this International Standard all necessary explanations in detailed illustrations or specif
