Compared with.2007, in addition to structural adjustments and editorial changes, the main technical changes are as follows.
a) Some normative reference documents have been changed to be consistent with ISO 1832.2017 (see Chapter 2, Chapter 2 of the.2007 edition);
b) Added terms and definitions (see Chapter 3);
c) Deleted the unequal-sided unequal-angled hexagon "F" (see Table 1 and Table 4 of the.2007 edition);
d) The basic size d of the inscribed circle of the blade shape V is changed to the allowable deviation value of m for the "12.7" blade (see Table 5,.2007 edition
table 5);
e) The blades with the basic dimensions d of "15.875" and "19.05" of the inscribed circle of the blade shape V are deleted (see Table 5 of the.2007 edition);
f) The letter code of the double chamfered blade has been changed from "Q" to "K" (see Table 10, Table 10 of the.2007 edition);
g) Added full cutting edge letter code "F" (see 7.4);
h) Added Appendix C (see Appendix C).

Indexable insert model representation rules for cutting tools
1 Scope
This document specifies the rules for the model representation of indexable inserts of cemented carbide or other cutting materials for cutting tools.
This document is applicable to indexable inserts of cemented carbide or other cutting materials for cutting tools, as well as to inserts with cubic boron nitride and inserts.
Polycrystalline diamond blade.

3 Terms and definitions
There are no terms and definitions that need to be defined in this document.
4 Model representation rules
The indexable insert model indicates the rule with nine codes to characterize the size and other characteristics of the insert. Code ①~⑦ is required, code
⑧ and ⑨ are added when needed.
According to the provisions of ISO 16462 and ISO 16463, the model designation rules of insert blades use twelve codes to characterize the size of the blade.
And other characteristics. Code ①~⑦ and
Open, see example 2.
In addition to the standard code, manufacturers can use supplementary codes to indicate one or two blade characteristics to better describe their products (if not
Same slot type). The code is separated from the standard code by "-" and cannot contain the characters used in ⑧, ⑨, and ⑩.
It is recommended not to add or expand the representation rules specified in this document. If you really need to add or expand the code that is not provided in this rule
It is best not to increase the number of digits, but to increase the symbol in the corresponding digits to maintain consistency with this document.
