Foreword
This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB/T 2077-1987 "Cemented carbide indexable insert fillet radius": Compared with GB/T 2077-1987, except
In addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Added indexable insert fillet radius classification (see Chapter 4);
b) Added a schematic diagram of the fillet radius of non-circular blades (see 5:1);
c) Added turning insert corner radius without fillet, 0:03mm, 0:05mm, 0:1mm (see Table 1);
d) Added the corner radii of special turning inserts and milling inserts to 0:6mm, 1:0mm, 1:5mm, 3:0mm and 4:0mm
(See Table 1);
e) Changed the fillet radius of non-circular blades from "2:4mm" to "2:5mm" (see 5:1, Chapter 1 of the 1987 edition);
f) Added the schematic diagram of the fillet radius of circular inserts and the fillet radius of circular turning (milling) inserts (see 5:2):
This document is modified to adopt ISO 3286:2016 "Single-point cutting tool fillet radius":
Compared with ISO 3286:2016, this document has made the following structural adjustments:
---Chapter 5 corresponds to Chapter 2 in ISO 3286:2016;
---Chapter 6 corresponds to Chapter 3 in ISO 3286:2016:
The technical differences between this document and ISO 3286:2016 and their reasons are as follows:
---Added the classification of indexable insert fillet radius (see Chapter 4) to make the classification of carbide indexable inserts more standardized;
---Added the schematic diagram of the fillet radius of non-circular inserts and the fillet radius of turning inserts without fillet, 0:03mm, 0:05mm, 0:1mm
(See 5:1), to adapt to the development of the industry;
---Added the corner radii of special turning inserts and milling inserts to 0:6mm, 1:0mm, 1:5mm, 3:0mm and 4:0mm
(See 5:1), to adapt to industry development and improve the applicability of this document;
---Added a schematic diagram of the fillet radius of circular inserts and the fillet radius of circular turning (milling) inserts (see 5:2) to adapt to the development of the industry
need;
---Deleted the imperial dimensions of the fillet radius in Table 1 of ISO 3286:2016, which is more suitable for my country's national conditions:
The following editorial changes have been made to this document:
---Deleted informative Appendix A and references:
