There are shown results of high-speed end milling experimental researches of critical hardened steel parts in fuel control equipment of modern aircraft gas turbine engines (GTE) with the purpose of optimum cutting mode definition ensuring the roughness Ra ≤ 0.63 mkm for the surface worked and deviation from the plane not more than 0.015 mm. The empirical mathematical models of high-speed milling are obtained and optimum cutting modes are defined.
