Bends in sheet metal are manufactured using sheet metal brakes.
Relief in sheet metal.
In the corner relief propertymanager under scope select the sheet metal body to which to apply the corner relief.
Select an item see the note below.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.
Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.
The flange which does not have relief will result in a greater amount of distortion or tearing of the adjacent material.
Lists corners to which you can apply corner relief.
When designing parts for laser cutting one should not make holes smaller than the thickness of the material.
Do one of the following.
A 1 degree tolerance on all bend angles.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
Click corner relief sheet metal toolbar or insert sheet metal corner relief.
Bend reliefs in sheet metal.
Select a hard edge bend face flange face or 3d solid entire model.
Lets you select the sheet metal body to which the corner relief is applied.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
When you apply a relief option to the selected corner the list shows the option applied.
Choose create relief in the sheet metal menu.
Click the create relief tool button on the sheet metal ribbon tab.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
Bend relief and collars near pierced areas strengthen sheet metal parts.
Enter relief size by bend radius ratio or force bend reliefs.
Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.

Preventing tearing and part deformation during the bending process.
Though bend relief lengths and widths vary between projects they all share a common goal.
For example if you make a partial flange as above using all the defaults the software makes relief cuts at the end of the bends as shown to the right.
Under corners click collect all corners to list all corners in the sheet metal body.
As per sheet metal design thumb rules the depth of bend relief should be greater than or equal to the inside bend radius of the bend and the width of the bend relief should be the same as the sheet metal thickness or more.
You can add a corner relief to a single sheet metal body.
