Abstract The paper considers influence issues of modes of milling cylindrical gears by hobbing cutters on the parameters of surface quality of the treated teeth, selection of milling mode, relevance of the performed research, possibility of using its results for the design of technological processes of manufacturing cylindrical gears, quality control of teeth surfaces both when cutting teeth and in finished gears. The article gives a method, conditions and main results of experimental study of the influence of gear milling modes by a worm milling cutter (feed S, mm/min; cutting speed V, m/min) of cylindrical gears on the roughness parameter Ra, μm; microhardness Hμ, MPa; macroscopic and microscopic stresses of σ1 and σ2, MPa; of the tooth surfaces. It is shown in particular that the dependence of Ra on V and S with sufficient accuracy (the average relative error of the coupling equation εср is 5.2–26.5 %) can be described by a firstdegree polynomial, and the dependences of Hμ, σ1 and σ2 on V and S with sufficient accuracy (εср = 4.7–12.8 %) can be described by a second-degree polynomial. It was found that the feed S has a 2.5–14 times greater effect on the change in Ra, Hμ, σ1 and σ2 than the cutting speed V during gear milling of cylindrical gears. A method for optimizing the cutting modes S and V is proposed and described, taking into account their influence on the main parameters of the process of gear milling of cylindrical gears with worm milling cutters.
