Unfavorable working conditions should be considered work with a variable depth of cut, with intermittent feed, with shocks, vibrations, with the presence of a casting skin and abrasive inclusions in the material being processed.
Depending on the material being machined and the type of chip being removed, sintered hard alloys are divided into three main cutting groups: P, .VI and K.
Depending on the types and modes of cutting, the main cutting groups are divided into application groups in accordance with Appendix 2.
Application groups are indicated by the letter of the main cutting group and a numerical index, which characterizes the change in the type of processing, cutting mode and properties of the carbide.
The higher the pure index in the designation of the application group, the lower the wear resistance of the carbide and the allowable cutting speed, but the higher the strength of the carbide and the allowable feed and depth of cut when machining.
In addition to the application groups established in this standard, it is allowed to additionally establish no more than one intermediate application group, the numerical index of which must be intermediate between two adjacent application groups, for example K15 (between K10 and K20).
The AI application group may be subdivided using the following designations: I) 1.1: P01.2 and P01.3.
The introduction of intermediate application groups is possible only if the hard alloy differs significantly in wear resistance and strength from alloys belonging to neighboring application groups.
The designation of grades of hard alloys should not coincide with the designation of the main cutting group and application group.
The letter “C” is added to the designation of the application group for coated hard alloys, for example, RZOS; K20S.

* Unfavorable working conditions should be considered work with a variable depth of cut, with intermittent feed, with shocks, vibrations, with the presence of a casting skin and abrasive inclusions in the material being processed.
Depending on the material being machined and the type of chip being removed, sintered hard alloys are divided into three main cutting groups: P, M and K.
Depending on the types and modes of cutting, the main cutting groups are divided into application groups in accordance with Appendix 2.
Application groups are indicated by the letter of the main cutting group and a numerical index, which characterizes the change in the type of processing, cutting mode and properties of the carbide.
The higher the index number in the application group designation, the lower the wear resistance of the carbide and the allowable cutting speed, but the higher the strength of the carbide and the allowable feed and depth of cut when machining.
In addition to the application groups established in this standard, it is allowed to additionally establish no more than one intermediate application group, the numerical index of which must be intermediate between two adjacent application groups, for example K15 (between K10 and K20).
Application group P01 can be subdivided using the following designations: P01.1; P01.2 and P01.3.
The introduction of intermediate application groups is possible only if the hard alloy differs significantly in wear resistance and strength from alloys belonging to neighboring application groups.
The designation of grades of hard alloys should not coincide with the designation of the main cutting group and application group.
The letter “C” is added to the designation of the application group for coated hard alloys, for example, RZOS; K20S.
Data on belonging to the application groups of grades of hard alloys established in the standards of the CMEA member countries are given in Appendix 5.
