ZD flat cake students are replaced by hinged swinging disc 2, on which is mounted a milling cutter with rotation centers located above and offset from the center of the disc inserts. On top there is the knife machetes has a trapezoid shape, normally they are arranged an outer blade, a blade in succession. When adjusted for the processing plant so that the top hat to divide machining gear wheel with flattened top of birth (2126 figure), the first plane of the blades exposed tooth cone tooth.
According to this principle, 3 rotary head with machetes cutting speed v (nd), this rate is not tied to the other movements of the machine work. Before beginning work material is moved radial groove depth Sk to get teeth. In addition to the rotation around its axis, the first orbiting machetes also be done with motion hinged plate fits the student flat bread with gear machining ZD 1 is hinged on the machine spindle. Swaying motion of the disk hinged nd (ωd) (ie movement of wheel flats fit students) with the movement of the gear nc (ω1.2) must correspond billion transfer window: Z1.2
