Numeric ID 201021
Value Type PMTechValue

An evaluation range must be provided to determine the risk of flank fracture for bevel and hypoid gears according to FVA 223/xxiv.

In the default case, the evaluation range is determined factorial from the case hardening depth (CHD):

Start of the evaluation range: y_min = CHD * 0.5 (default)

End of the evaluation range: y_max = CHD * 3.0 (default)

Alternatively, they can be specified by the user.
