Bending is one of the most common sheet metal fabrication operations. Also known as press braking, flanging, die bending, folding and edging, this method is used to deform a material to an angular shape.. This is done through the application of force on a workpiece. The force must exceed the material's yield strength to achieve a plastic deformation.

Laser cut stainless steel is another very common application. The cut quality is excellent; using Nitrogen assist gas the level of detail achievable is higher than mild steel. It's obviously more expensive than mild steel, but its decorative finishes combined with its corrosion resistance make it widely used across many industries.

Laser forming is an incremental sheet-metal forming process that offers the advantages of high flexibility, requires no hard tooling, no external forces and easy clamping systems. The main limit of the process lies in small angles produced per pass that dramatically affects the process productivity. Actually, long time should be waited between consecutive passes to avoid surface oxidation ...

Nov 05, 2013· A new method was then developed to precisely determine the absorption factor by coupling numerical simulation of the laser bending results with the experimental results. It was found that each laser pulse causes a cycle of sharp temperature rise-drop in a silicon sheet. When the temperature in the heating zone is low, the sheet deforms elastically.
