This is the first standard ever to include a continuous calculation for bevel and hypoid gears for both face hobbing and face milling gear methods. Other types of damage such as scuffing, important issue for hypoid gears, and tooth flank fracture, can be calculated according Webflank fracture or subsurface fatigue that can eventually lead to the opposite tooth root section. The crack propagation rate the total damage of the gear set. Such sub-surface fatigue failures towards the loaded flank is smaller in comparison to the core, were observed — even at loads below the rated allowable ones due to the higher hardness.
