A.
Is extensively used for making bolts and rivets |
|
B.
Is used for reducing the diameters of round bars and a tube by rotating dies which open and close rapidly on the work |
|
C.
Is used to improve fatigue resistance of the metal by setting up compressive stresses in its surface |
|
D.
Consists of pressing the metal inside a chamber to force it out by high pressure through an orifice which is shaped to provide the desired form of the finished part |
