forging

shaping metal by heating and hammering

Forging is a process of forming metal parts by the use of heat and pressure Forging develops a grain structure in the metal, which makes it stronger in the direction that it has been stretched Forging is done in special molds called "dies", and when the dies are properly designed to take advantage of the grain structure introduced by the forging process, the resulting parts are stronger in the important directions than those manufactured by CNC machining See also Jeff del Papa's article on Forging, Casting & CNC Machining on this site

{i} act of forging, metalworking, work of a blacksmith

present participle of forge

The hammering or pressing of metal to join or shape it, usually at high temperatures

A process using hammers and an anvil or steel stakes From a given shape or mass of metal, the material is redistributed by controlled hammer blows to create the desired form

Forming a hot or cold metal into a fixed shape by hammering, upsetting, or pressing

The working of metal to some predetermined shape by hammering, upsetting, pressing, or rolling (or a combination of these processes); the metal can be hot or cold The most common metals forged include carbon, alloy and stainless steels; very hard tool steels; aluminum; titanium; brass and copper; and high-temperature alloys containing cobalt, nickel, or molybdenum There are four principal types of commercial forgings: drop forgings, where the shape has been formed by repeated blows by a hammer onto a bar or bullet placed between a pair of dies; upset forgings, where the cross-sectional area is increased while the thickness is decreased; roll forgings, whereby the shaping is done by two rotating rolls; and press forgings, where hydraulic pressure deforms the metal

Plastically deforming metal, usually hot, into desired shapes with compressive force, with or without dies

A piece of forged work in metal; a general name for a piece of hammered iron or steel

Heating the stock piece of steel in a forge (or other heat source) and hammering into shape on an anvil It is more conservative of steel, but can also be more time consuming Regardless of how close to shape a piece is forged, a small bit of grinding is still necessary to finish the piece Neither technique (forging or stock-removal) is better than the other; they are just different methods to achieve the same results

The act of deforming solid aluminium into either a particular shape by hammering or squeezing in a closed die, or deforming between flat platens

Shaping metal by impact or pressure The metal may be heated prior to shaping

The act of counterfeiting

To displace metal under compression by a locally applied force, usually at hot working temperatures

mechanical forming of a metal or alloy by heating and hammering

The process of producing a golf club in which the head is made from a series of forging dies stamping the head to final shape Forged heads are made of softer metals than are cast heads and require laborious hand finishing and chrome plating in order to produce a finished product

In metallurgy, the process of shaping metal and increasing its strength by hammering or pressing. In most forging an upper die is forced against a heated workpiece positioned on a stationary lower die. To increase the force of the blow, power is sometimes applied to augment gravity. The number of blows struck is carefully gauged by the operator to give maximum effect with minimum wear on the die. Forging presses employ hydraulic or mechanical pressure instead of blows; most can exert only a few hundred tons of pressure, but giant presses, used for forging parts of jet aircraft, are capable of up to 50,000 tons of pressure.

The act of shaping metal by hammering or pressing

A semi-finished metal product that has been hot formed into an engineered shape by any one of a variety of mechanical compressive forces Hammer forgings, open die, closed die and press forgings are some of these types
