The article discusses the issues of improving the technology of cutting teeth of cylindrical gears using modular precast disk milling cutter in various production conditions for gear milling, reducing the cost of tooling materials and facilitating the manufacture of precast disk mills by changing the design. The essence of this design is that when cutting teeth into gears with an involute profile, radial runout is eliminated to a minimum, since the gear cutting operation is carried out on the machine in which the turning was performed. The proposed new gear processing technology – with an involute profile shape and engineered efficient design of prefabricated disk cutters. The main place in the article is given to the design parameters of gear cutting mills, as well as their advantages and disadvantages. Much attention is paid to the determination of the structural and geometric parameters of cutters with various cutting patterns. The described methods are applicable for the design of tools in small-scale production of gears.
