The precise bevel gear grinding of epicycloids in a complet-ing process to the contrary is not pos-sible. A precisely defined flank form of the hard finished face hobbed bevel gears can be achieved by (hard) skiving (see also Chapters 9 “Cutting Methods”; and 11 “Hard Finishing, Grinding and Skiving”). Generating Gears of Bevel GearsThe worms can be produced by rolling, milling, or grinding. Worm gears, on the other hand, can be almost as tricky to make as bevel gears. Successful development of the contact pattern and tooth thickness depends on proper initial tool design and accurate adjustment of the hobbing machine to account for cutter re-sharpening.Gear Manufacturing Machines SpringerLink

Accuracy of Straight Bevel Gear by End Mill Using CNC
Straight bevel gears are usually manufactured with various machines and systems, and the tooth profiles are produced by grinding or machining by means of a tool with many cutting edges. In recent years, the straight bevel gear has been manufactured by an end mill using a CNC milling machine because the use of the auxiliary apparatus, The advantage of Zerol bevel gears is the low axial forces—like straight bevel gears— but their manufacturing process with complet-ing face mill cutters is significantly faster, and grinding as a hard-finishing process with dressable grinding wheels leads to highly pre-cise gear sets that are often used in aircraft applications.Tribology Aspects in Angular Transmission Systems
