b) Press forging

c) Machine forging

Fullering:

image
In Fullering, the material cross section is decreased and length is increased. Figure shows that the bottom fuller is kept in the anvil hole with the heated stock over the fuller. The top fuller is then kept above the stock and then with the sledge hammer. The force is applied on the top fuller which results in decreasing the cross section at that point.
