A sheet metal is a flatten piece metallic material. They exist in varied thickness depending on function. Thin ones called foils and thick versions are known as plates. Sheet metal fabrication is a manufacturing process that helps to produce different objects or even shapes through beating, bending, changing the shape, cutting, resizing, stretching as well as removing given materials from the sheets.
There are varied applications of fabricated metal sheets. They are popularly seen in everyday usage at home or in industries. Home appliances, automobile parts, steel buildings, bridges and aircraft bodes are examples where fabrication of sheet metal is applied.
Various types of metals are used to produce sheets. The examples are, bronze, aluminum, steel, copper, and tin including precious metals. Metal fabrication methods can be used to produce the required shapes by beating and reshaping.
Jewelries for instance, are made by forming, cutting and beating the precious metals into the desired structures and shapes. Application of particular fabricated metals normally depends on its physical properties. Those metals that possess magnetic characteristics are usually fabricated to make electrical transformers and machinery.
Sheet metal fabrication can be categories into two main steps, which are cutting and forming. It is possible to cut-out holes on a sheet of metal and come up with a 3D shape through application of force. The sheets can also be bent to create desired complicated contours.
Cutting is done to break the sheet metal into separate pieces. The pieces are cut into desired sizes. This process normally requires high shearing force for separating the pieces. Cutting of sheet metals is sometimes referred t as shearing process because of the high shearing force that is applied.
The shearing force is exerted on the metallic sheet using two sets of tools. One is set below and the other above the sheet. With a quick downward strike, fabrication is applied to break the sheet into separate pieces. Besides using shearing force, abrasive forces or heat is also used. In this method, laser beam, abrasive jets of water or plasma systems are used. They act as the main force for cutting the metal.
Forming of sheet metals is the method of fabrication where the applied force is intended to create deformation without breaking the metal. It makes it possible for the sheet to be stretched or bent to come up with the desired shape. The process involved in this method may include bending, spinning, roll forming, stretching and deep drawing.
Bending is done through the application of force to form an angle so that the desired shape can be obtained. Roll forming is basically meant to pass the metal sheet through different roll stations. It also helps to come up with different desired shapes. During spinning, force is applied on one side of rotating sheets.
The other method of sheet metal fabrication is deep drawing. Here, the sheets are forced to stretch in a die cavity. In this method of fabrication, the sheet in bent and also stretched simultaneously by use of a die to build different desired structures. It is possible to come up with any shape as long as the right method is used.
