Maximum pressure were optimized. By applying the optimal tool parameters, the maximum tooth contact
pressure is reduced by 45% and the maximum angular position error of the driven gear
by 60%, in regard to the spiral bevel gear pair with a pinion manufactured by a cutter of
straight-sided profile and of diameter determined by monly used methods.
