Cogging, which is also called as drawing out, is basically?

Forging and extrusion are manufacturing processes that shape materials. Forging: A process that involves hammering, pressing, or rolling metal into a specific shape. Forging is often categorized by the temperature at which it is performed, such as cold, warm, or hot forging. Extrusion: A process that involves pushing a material through a die to create a specific shape. The die is a small disk with an opening of a specific size and shape. The material is put under pressure through the die to create the desired shape. Many ceramics are manufactured by extrusion because the process allows... Show more

Forging: A process that involves hammering, pressing, or rolling metal into a specific shape. Forging is often categorized by the temperature at which it is performed, such as cold, warm, or hot forging.
Extrusion: A process that involves pushing a material through a die to create a specific shape. The die is a small disk with an opening of a specific size and shape. The material is put under pressure through the die to create the desired shape. Many ceramics are manufactured by extrusion because the process allows efficient, continuous production. 

Here are some types of extrusion: Hot extrusion, Cold extrusion, Indirect extrusion, Direct extrusion, Hydrostatic extrusion, Hooker extrusion, Impact extrusion. 

Here are some types of forging:
Impression die forging (closed die)
Open die forging
Cold forging
Seamless rolled ring forging
