Abstract

The process of the hardening effect formation when using an aerodynamic sound installation is explained, the temperature of cold brittleness for high-speed steels of three grades, approximately equal to 280 °C, is experimentally determined. The dependence of the frequency-amplitude characteristics on the outlet channel length of the installation and the pressure of the supplied air is studied. A technology and processing modes for axial milling tool made of highspeed
steels are proposed to achieve maximum tool life when using a tool with shock loads, due to aerodynamic sound effects: preheating temperature 280 °C; hardening time 3 min; the use of successively mode 1 and mode 2 of the
installation for aerodynamic sound exposure, which makes it possible to increase the operating time of end mills made of high-speed steels by 1.55 times, which is very effective for this type of tool.
