When gear teeth are cut on a gear blank, the manufacturing process consists of the following steps:
(a) Blank manufacture;
(b) Tooth cutting;
(c) Heat treatment;
(d) Tooth finish cutting.
All the steps listed above may not be used in the manufacture depending on the requirement. For example, non-hardened gears may not require heat treatment. If the accuracy required is not very high, special tooth finish cutting will not be carried out. The sequence of steps is generally as enumerated above, but it may differ. For example, in automobile gear manufacture the tooth finish cutting is carried out before heat treatment.
