Different Types Of Bends
Step Bends
Step bending is the process of taking a large bend radius and dividing it up into multiple smaller bends in order to approximate a larger radius. Sometimes referred to as bump bending, step bending is very useful for achieving a curvy look.
Hem Bends
A hem bend is an edge of sheet metal that is bent 180 degrees and flattened on top of itself. Hem bends add another layer of rigidity to an edge of a part, which is especially useful in long sections of a sheet-metal part that could be unstable.
Internal Bends
An internal bend is a bend that is placed on a particular area of a part where material surrounds the bend, rather than a conventional bend that is placed at the outermost edge of a part. Inset bends is a bend that's inset a small amount from the part edge.
Jog Bends
Both jog bends and material-offset bends are often used for adding clearance to a design. While jog bends and material offset bends achieve a similar result, the bending process for each is different. Material offset bends are performed in a single operation, while jog bends are performed in two separate operations.
W Bends
W Bending is a technique used to form deep U-shaped profiles without the need for specialized tooling. Also known as "back bending," W Bending replaces the need to have two separate parts that are welded together to create the U-Shape profile.
