Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...

Some of example of forming processes are: Forging; Extrusion; Rolling; Sheet metal working; Rotary swaging; Thread rolling; Explosive forming; Electromagnetic forming; Plastic extrusion; Die forming (plastics)#Process; Food extrusion#Process
The process combines the advantages of casting and forging. The process is named after the fluid property thixotropy, which is the phenomenon that allows this process to work. Thixotropic fluids flow when sheared, but thicken when standing. [3] The potential for this type of process was first recognized in the early 1970s. [3]
Gear manufacturing refers to the making of gears. Gears can be manufactured by a variety of processes, including casting , forging , extrusion , powder metallurgy , and blanking . As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.
Rule based DFM analysis for forging is the controlled deformation of metal into a specific shape by compressive forces.The forging process goes back to 8000 B.C. and evolved from the manual art of simple blacksmithing.
Flat stock is heated and fed through specially-shaped rollers that both form the steel into a tube and simultaneously provide the pressure to weld the edges into a continuous seam. [23] Diffusion bonding is a common method for forge welding titanium alloys in the aerospace industry. In this process the metal is heated while in a press or die.
Forming processes tend to be categorised by differences in effective stresses. These categories and descriptions are highly simplified, since the stresses operating at a local level in any given process are very complex and may involve many varieties of stresses operating simultaneously, or it may involve stresses which change over the course of the operation.
