Abstract
A gear is manufactured by heating a blank up to a warm working temperature range, upsetting and piercing the blank through warm f=orging, forming gear teeth on the blank through warm extrusion to produce an intermediate blank which is substantially of a gear shape, and then finishing the gear teeth accurately through cold sizing. The gear can be manufactured highly accurately with a good yield without requiring other intermediate processes such as normalizing and shot blasting.
