The engagement and rolling interrelations mean that the addendum radius of the die profile penetrates the target contour of the gear tooth root area, undercutting the usable involute flank. The ensuing rolling defect is considered to be damaging if the load-bearing flank of the tooth is undercut so much that it impairs the load-bearing capacity of the gear teeth during gear engagement. This effect during rolling can be counteracted with a positive addendum modification. The peak value of this addendum modification is limited by the formation of a peak on the top land of the gear tooth.
