Research on a Generating Method of Spiral Flutes of Hourglass Worm Gear Hob
, 2017 All of the cutting edges on an hourglass worm gear hob have different shapes and spiral angles. If the spiral angles are small, straight flutes are usually adopted. But for the hob with multiple threads, the absolute values of the negative rake angles at
