| Abstract: | Based on the technology of machining the tooth profile of hobbing shaving cutter for cutting hardened gear, the approximate forming of the tooth profile on normal section is carried out by means of straight line fitting, arc fitting and hyperbola fitting. The calculation results of approximate forming errors show that the error of straight line fitting is large although the dressing of grinding wheel is easy, the error of arc fitting is minimum but the dressing of grinding wheel is a little hard, the error of hyperbola fitting is very small and the dress of grinding wheel is easy too. |
