Text on gear design frequently mention the need to increase addendum length for a pinion with less than (20) teeth to avoid fillet interference. Such modification requires an equivalent decrease in addedndum length of the mating gear. However, I have yet to see how to calculate this modification based on pitch, pressure angle, tooth thicknesses, and operating center distance.
