The phenomenon when the tip of a tooth undercuts the root on its mating gear is known as interference.
If the radius of the addendum circle of the wheel increases beyond a limiting value, then the tip of a tooth on the wheel will cause interference with the tooth on the pinion and vice versa.
Interference may only be prevented if the addendum circles of the two mating gears cut the common tangent to the base circles between the points of tangency.
If the addendum for gear and pinion are to be equal, the addendum radius of the wheel decides whether the interference will occur or not. Because the addendum circle of the wheel passes through the limiting point on the line of action (interfering with the pinion) before the addendum circle of the pinion passes through the limiting point on the same line. So, in this case, the chances of interference are more for the wheel than the pinion. Here the tip of the wheel will undercut the flank of the pinion.
