Spiral Bevel and Hypoid Gear Cutting Technology Updatehobbed gears can also be finished by skiving. Grinding is not recommended for facehobbed gears, as discussed later in the paper. Face hob cycle times are often faster than face milling due to the continuous indexing method, and face hobbing is always a completing process. In face milling, one slot is cut at a time, Figure 1—Single indexing.
