A number of holes evenly spaced in a regular pattern on a sheet of metal

A flat sheet to the desired shape

A hole (other than cylindrical) in a sheet of metal by the punch and the die

A cylindrical hole in a sheet of metal by the punch and the die

Bare metal electrode and the work

Carbon electrode and the work

Metal electrode and the work

Two tungsten electrodes and the work

Is used for reducing the diameters of round bars and a tube by rotating dies which open and close rapidly on the work

Is extensively used for making bolts and rivets

Is used to improve fatigue resistance of the metal by setting up compressive stresses in its surface

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

None of these
