Prior studies of surface roughness generated by machining the cutting edge of the tool does not remove the need for additional studies under specific processing conditions, for example, turning a specialized corrosion resistant stainless steel grade 09H17N7U. There are no regulatory recommendations to ensure the necessary quality of detail in the roughness parameters for this steel (pre-existing are outdated). The scope of application of this steel is rapidly expanding due to its unique performance properties, physical and mechanical characteristics. The authors performed such a study in relation to turning with various tool materials.

The possibilities of processing materials with hardness up to 65 HRC with carbide end mills are shown. Examples of milling hardened tool steels and sandwich-type materials based on structural steels with high-hardness surfacing are given. The results of the use of various types and brands of tools are considered. A method for controlling the dynamic parameters of a cutting system for high-hardness materials based on controlled acoustic emission is described.
