ABSTRACT:
A method for forming a groove by plastic deformation to provide improved working efficiency. A hole 4 having a diameter larger than a width W of a desired groove 6 and a depth deeper than the desired depth of the groove 6 is formed in an end face 2 of a rod 1. Subsequently, the groove 6 is formed by plastic deformation to partially overlap the hole 4. The plastic working to form the groove may be carried without the use of a die.
