I am working on this. Since I am in the powder metal gear business we can shape the root to whatever we want -reducing stresses.
What I have heard from MFG's is that when they try to increase gear root radius to reduce bending stress of the gear root, leads to higher tool wear. Sometimes it is not possible for kinematic reasons (interference)
If anyone knows more about this please mail me and post
