Carried out tip relief

Bevel gears are usually crowned. This profil crowning (tip relief) is recorded according to the calculation specification DIN 3991. If a smaller value than the effective head relief according to DIN 3991 is entered for the executed tip relief C_a, C_a is used for calculation, otherwise C_eff is used. The calculation is performed on the safe side for gears with a stronger profile correction. This calculation does not correspond to DIN 3991, in which the tip relief factor X_Ca is set to 1.0 as soon as C_a deviates from C_eff. Without input, C_a = C_eff is set according to DIN 3991.
