Purpose. The aim of the work is to study the phenomenon of profile cutting gear hobbing cutters in spatial gearing Hiller - wheel and the development of recommendations to reduce the impact of this phenomenon and to increase efficiency of cutters that cut gears with few teeth.
Design/methodology/approach. The dependencies to find the cusps (singular point) on the surface of the gear, which is formed by a helical initial tool surface milling. Defined and investigated the influence of the design parameters of hobs on cropping profile gears. Their comparative analysis with the case where the surface of the gear rack is formed flat. Keywords: gears, helical milling, cutting tools, pruning
Findings. On the basis of the research proposed design of the worm milling cutter for making gears with few teeth, which yields a profile without cutting gear and by that on the secondary side of the edge profile angle cutter such greater angle as standard cutters and the back side angle will be more important than standard cutters, consequently proposed cutters should have greater efficiency.
