Abstract: This paper describes an investigation on the rocking forming of the end teeth of a starting gear* End teeth which cannot be worked through metal cutting, can be formed by the rocking forging technology，whereby the purpose of economizing material and working time and increasing production efficiency can be achieved. The authors have studied many deformation regimes of rocking forming. Using resistance strain gages and photoplasticity methods，it is proved that the parameters selected for the rocking forging technology are suitable for that purpose.

Key words: starting gear, end teeth, cold rocking forming
