Most metals can be bent on an unidirectional line, however this is not always possible. Instead, the bends are often performed in a series, with each bend being overlapping the next. This process can produce many different shapes, ranging from soft curves to sharp edges.
Before beginning the process of fabrication, a design should be created in 3D and then checked for accuracy. It must be in line with the specification of the product and finished to the desired level. The materials and process are determined by the engineering team. The blueprint is then used by the fab shop to design the product. During the fabrication process, specialists carry out a variety of procedures to check the part’s geometry and other properties. This includes cutting, bending, and punching. Surface finishes are also employed to improve the final appearance.
Another process in sheet metal fabrication is the forming. This method alters the shape of the material without altering its mass. There are many methods of creating the metal, including bending, stamping, and stretching. In general, stamping requires dies that reshape the material.
What Applications Require Sheet Metal Fabrication aluminum is the most commonly used material for sheet metal fabrication. This reasonably priced metal is extremely versatile and comes with several desirable features. It’s weather resistant, chemically-resistant, weldable, and ductile, making it a good choice for many projects. It can also be used at room temperatures which makes it cost-effective in mass production.
Another option for fabrication of metal is AK steel. This type of alloy does not work like cold-rolled steel, but it has advantages for certain applications. AK steel is better for panels with deep contours while grade 6061 T6 is an excellent option for structural applications.
CNC laser cutting is a fantastic method to cut metal. In contrast to traditional hammer and sawing techniques, CNC lasers can produce extremely precise cuts, without contact. The thickness of the metal determines the speed of the process. Fiber-optic lasers are a great tool to measure thin metals while CO2 and multi-gas lasers may be used to gauge thicker metals.
The process of welding is an important component of the fabrication process. It is a typical process in sheet metal fabrication. Sheet metal parts are often held together with fasteners. Riveting and brazing are also critical assembly processes. These techniques are often complemented by adhesives. The heat is used to fuse the metal. Different metals require different weldable materials.
Miter, band or chop saws are used to fabricate sheet metal. For instance, band saws use sharp blades to cut sheet metal. Chop saws, on the other hand, utilize two blades to cut metal in the same direction. These tools can make precise cuts.
Shearing is another process used in the fabrication of sheet metal. The results of this process are similar to bending, and the sheet metal is pushed between two dies. Another less well-known process is hydroforming that involves stretching the blank over a die.
