Here's hoping for someone to enlighten us about cutter grind geometry as it relates to small negative cutter angle.

UNITOOL spiral bevel cutters are special grinds that crown teeth to yield shortened tooth bearing for what would otherwise be conjugate contact. Gleason has certainly done some special cutter geometry to achieve lengthwise tooth crowning. Gleason determines bearing over narrow ranges of DP by specifying a small range of cutters, again similar to the selection of lettered cutters for 104 straight bevel.

Okay, I'm rattlin' on and offering nothing, but this is a very interesting subject. I really hope someone has the formulas, specifications, theory, etc. to make this clearer.
