The work of preparing

13、 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 organizations, governmental and non-governmental, in liais

14、on with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Direc

15、tives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).Attention is drawn to the possibility that

21、tools in hard cutting materials or any other cutting materials, in order to simplify orders and specifications for such inserts.It also specifies the designations for cubic boron nitride (BL, BH, BC) inserts, tipped and solid, as well as polycrystalline diamond (DP) inserts, tipped.2 Normative refer

26、for designating the dimensions and other characteristics; the first seven symbols (symbols to ) shall be used in every designation. Symbols and may be used when necessary.For tipped inserts in accordance with ISO 16462 and ISO 16463, the designation code comprises 12 symbols for designating the dime

27、nsions and other characteristics; symbols to as well as and shall be used in every designation. Symbols , and may be used when necessary. Symbols and shall be separated by a dash as shown in Clause 4, example 2.In addition to the standardized designation for indexable inserts and tipped inserts, a s

28、upplementary symbol consisting of one or two characters may be added by the manufacturer for a better description of his/her product (for example, different chip breakers), provided this symbol is separated from the standardized designation by a dash and that it does not contain letters specific to

Rather than adding symbols not provided for in this system, it is p

30、referable to add all necessary explanations in the form of detailed sketches or specifications to the designation in accordance with this document.However, if the letter symbol “X” is used in position 4 of the designation, it is allowed to use, in positions 5, 6 and 7, symbols representing values no

31、t appearing in this document, but which shall be described explicitly using the sketch or the detailed specifications given in 5.4.The significance of the symbols constituting the designation code is as follows: Letter symbol identifying insert shape (see 5.1)Compulsory symbols for indexable inserts

37、ion of the indexable inserts shall conform with ISO 3002-1, with the following conventions: the insert is considered in the tool-in-hand system; the reference plane, Pr, is parallel to the base of the insert; the assumed working plane, Pf, is perpendicular to the reference plane, Pr, and is parallel

38、 to the assumed direction of feed motion. This plane is defined only in the case of inserts having one or more wiper edges.The assumed direction of feed motion is taken parallel to the considered wiper edge (see Note 1 to Table 9).For the relationship between designations in this document and the IS
