In this article we will discuss sheet metal design guidelines for manufacturing parts using sheet metal press bending.
Sheet metal round bending.
Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal.
Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same.
Choose a bend radius that matches your minimum bend.
Creating a change in the part s geometry.
Bending of sheet metal is a common and vital process in manufacturing industry.
Bend radii minimum bend sizes.
Determine your minimum bend by measuring the distance from your closest feature i e.

Following all sheet metal design guidelines is very difficult in the complex part.
But testing these exceptions before design release is a good practice.
Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.
Therefore exceptions can be there for complex features design.
As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.
