Ensure the quality of the surface layer of parts in high-speed end milling of hardened steels

The article discusses with the development of technology, materials that are difficult to process using existing technologies are widely used. For example, hardened steels of high hardness are processed by grinding. This leads to the formation of a surface layer with tensile residual stresses, burns and a large inhomogeneity of the structure, which negatively affects the functional properties of the manufactured parts. The advent of high-speed machining (HSM) has made it possible to increase cutting performance by several times. However, in order to further improve the process, it is necessary to pay special attention to the quality of the products. The leading role is played by ensuring the quality of the surface layer.
