The paper presents a method for developing an accurate generic bevel gear model including both the face
milling and face hobbing processes. Starting with gear blank geometry, gear and pinion basic generator
machine settings are calculated. The contact pattern and rolling quality are specified and held to the second
order in terms of pattern length, contact bias and motion error. Based on the setup, a grid of tooth points are
found including the tooth flank, fillet and, ifit exists, the undercut area. It is proposed as the model for the next
generation ofbevel gearstrength calculations in that the procedure produces true bevel gear geometry, uses
blank design parameters as input and is vendor independent except for cutter diameter.
