Types of metal forming in metal fabrication

Forging: The shaping of metal using localized compressive forces. Forging is often classified according to the temperature at which it is performed (i.e. cold, warm, or hot forging)

Rolling: The process in which metal stock is passed through a set of roll to reduce the thickness is known as rolling. Rolling is classified according to the temperature of the metal rolled. If the temperature is above its recrystallization temperature then the process is known as hot rolling and if below then cold rolling.

Extrusion: The process of creating objects of a fixed cross-sectional profile is known as Extrusion. A material is pushed or drawn through a die of the desired cross-section.

Drawing: The process of forming sheet metal into shapes or stretched over a form is known as drawing. Deep drawing is a type of drawing where the depth of the part can be greater than its diameter. Deep drawing is generally done in multiple steps called draw reductions.

Bending: The process of producing V-shape, U-shape, or channel shape along a straight axis in ductile material, most commonly Metal is known as bending. During bending, the workpiece is bent to form flanges, contours, curls, seams, corrugations and other geometries by means of applying force through hydraulic, pneumatic and electrical machines.

Spinning: The process in which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part is known as spinning. Spinning can be performed by CNC lathe.
