Sheet Metal Bend Relief

Sheet Metal Bend Relief – Also known as press braking, flanging, die bending, folding and edging, this method is used to deform a material to an angular shape. Relief cuts are notches made in sheet metal to alleviate stress and prevent cracking during bending. December 15, 2023 modify a bend relief (the small cut made where the bend end meets a free edge), and by specifying a shape, and either a depth. The width of the relief should be a material thickness or greater, preferably a material thickness + 1/64.

It’s a sophisticated strategy that mitigates the challenges introduced by bending. Bend relief is a term used in sheet metal design to describe a small cut or notch made at the intersection of two bend lines. Bends can be short or long depending on what the design requires. Without a bend relief, the part may slip unpredictably in the tooling as the bend is made.

(0.762mm) wide that prevent the material from bulging outwards at the. Under bend corner treatment, specify the setback value to. These are small notches roughly 0.030 in.

Each bend has two edges, and some bends require two, one or no reliefs. They’re beneficial when making tight bends or working with harder metals. Tech tips how and when to add bend reliefs to sheet metal parts posted on august 15, 2022 by protolabs take a piece of paper and try to fold just the middle inch of it to form a flap.

Speaking of corners, you should also plan on a bend relief anywhere that two flanges come together. This is done through the application of force on a workpiece. Sheet metal bend relief isn’t just a design technique;

Simulation studies past experience reverse engineer existing products experimental studies minimum inside bend radius for sheet metal parts recommended inside bend. Using a cad tool to help you visualize your bend part can help, but if you’re still not sure whether your bend requires relief or not, below are some examples of bends that do and don’t require relief. For example, if you make a.
