	Sheet metal forming - Wikipedia, the free encyclopedia
		Sheet metal forming refers to various processes used to convert sheet metal into different shapes for a large variety of finished parts such as aluminium cans and automobile body panels.
		Key to the formability of sheet metal is its ductility.
		One recent sheet metal forming technique is called Incremental Sheet Forming (ISF), and is named because it forms sheet metal by a large series of small incrmental deformations.

	Sheet metal - Wikipedia, the free encyclopedia
		Sheet metal is generally sheets less than 6 mm.
		Sheet metal is produced by reducing the thickness of a long work piece by compressive forces applied through a set of rolls.
		During punching or shearing, the sheet metal is cut by using a punch and die.

		Sheet metal is an "old" material, and one could be tempted to believe, that all the necessary knowledge and methods within the area of sheet metal forming have been established to such a degree, that no further research in this area is required.
		The interactions between the sheet metal specimen, the material properties and the forming process are extremely complex, and in order to be able to investigate and optimise a sheet metal forming process, it is necessary to have methods and equipment for determining material data, different experimental methods e.g.
		Metal forming processes are characterised by large displacements and rotations, strong non-linearity, complex contact problems and complex tool geometries and they are among the most difficult to simulate.

	Apparatus for forming sheet metal duct work - Patent 4367640
		Sheet metal fabrication requires the forming of ducts of a general conical configuration ranging from symmetrical cones to offset cones.
		In sheet metal shops this is performed by cutting a flat blank from the material to be formed by marking the material with a multiplicity of element lines of varying lengths which establishes the shape of the blank to be formed into the sheet metal duct.
		Using conventional forming rolls of either the pinch or pyramid type the blank is fed through the rolls maintaining the element lines parallel to the feed rolls by continuous manual adjustment of the blank position.

	Simulation of sheet metal forming processes
		Sheet metal forming is a widely used production process: in 1998, 265 million tons of steel sheet and 9 million tons of aluminum sheet was produced worldwide which was approximately 35% of the total steel and aluminum production.
		Sheet metal forming is characterized by a stress state in which the component normal to the sheet plane is generally much smaller than the stresses in the sheet plane.
		In stretch forming the material is fixed under the blankholder, leading to thickness reduction in the remaining part of the blank in which the stresses are tensile in almost all directions.

	Cheltenham Tool Company - Sheet Metal Forming
		Hydro-mechanical forming produces components that are not as intricate and relatively simple in shape when compared to fluid formed components, however the ability to alter the fluid pressure during the forming process allows very high levels of small detail to be left on the component.
		Because of the metal to metal characteristics of this type of forming it is almost impossible to produce the accuracy found in the other methods we use, consequently it is used as a complementary method to our other forming techniques.
		Fluid forming of sheet metals was developed by the Saab company in Sweden during the early 1950's to form aircraft parts.

	Opportunities in High-Velocity Forming of Sheet Metal
		Forming typically is accomplished with the motion of massive matched tools with precise control of static forces and slow displacement rates.
		Techniques for reproducibly and economically launching sheet metal toward dies at high velocity not only exist but are ready for use.
		The surface of sample sheets also was circle gridded and the strain states after deformation were plotted on a forming limit diagram.

	IVF - Sheet metal forming
		The main effort is directed towards the sheet metal forming methods; deep drawing, stretch forming, hydro forming and roll forming.
		In sheet metal processing, the tribological system is a result of the interaction between the sheet metal material, the tool, the lubricant, the process and the geometry of the product.
		When producing sheet metal details with dimensional accuracy it is necessary to control the friction between the sheet material and the press tool.

	Sheet Metal Forming: A Review
		The membrane stresses in the sheet far exceed the contact stresses between the tools and the sheet, and the through-thickness stresses may be neglected except at small tool radii.
		Figure 1 shows a stamping die with a lower counter-punch or bottoming die, but contact with the sheet at the bottom of the stroke will be on one side only, between the sheet and the punch or between the die and the sheet.
		In this case, the regions sampled in thick sheets tend to lie closer to the centers of the neck and, therefore, have a higher average strain.

		We believe the end result of this vision will be that many sheet metal components will be able to be fabricated with a smaller number of operations (i.e., less expensive) and that it will enable the fabrication of many components from difficult materials such as aluminum.
		Areas of research emphasis include: high velocity and strain rate formability, electromagnetic forming process development, validation of numerical simulations, and education and dissemination of knowledge about the practice and theory of electromagnetic metal forming.
		Sheet aluminum offers many powerful advantages to automakers, but it is also notoriously difficult to form.

		In sheet metal forming processes, the usage of liquid lubricants can be decreased by using self lubricated tribo surfaces which will result in more environmentally friendly workshops.
		The sheet materials investigated include Zn and 55%Al-Zn metal coated steel sheet, which in general are difficult materials to form under dry conditions since they are sticky and thus have a high tendency to adhere to the tool surface.
		The deposition of thin organic coatings on the steel sheet metal has been found to be promising in order to control the friction and to avoid metal-metal contact resulting in galling.
