Straight Bevel Gears, octoid toothing is introduced and implications on the cutting processes of these gears are analyzed. Tredgold approximation is then used to define the equivalent cylindrical gears and their main characteristic quantities, including the minimum number of teeth to avoid interference. Short notes are
