You can add a corner relief to a single sheet metal body.
Relief sheet metal.
Creates a corner relief where two bends meet.
See the picture on the side for an example.
The corner relief is applied at the common intersection point of the bend lines.
Do one of the following.
Click the create relief tool button on the sheet metal ribbon tab.
Click corner relief sheet metal toolbar or insert sheet metal corner relief.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
A 1 degree tolerance on all bend angles.
The model must have three bends where the bend lines meet.
Type smreliefcreate in the command bar.
Click insert sheet metal corner relief.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
Similarly insufficient bend radius may lead to brittle fracture failure of the sheet metal.
Enter relief size by bend radius ratio or force bend reliefs.
Under corners click collect all corners to list all corners in the sheet metal body.
Though bend relief lengths and widths vary between projects they all share a common goal.
Creates a corner relief where three bends meet at one common point.
Preventing tearing and part deformation during the bending process.
Choose create relief in the sheet metal menu.
In the corner relief propertymanager under scope select the sheet metal body to which to apply the corner relief.
Each corner of the t is at risk of tearing if the relevant line segment is bent without proper bend relief.
Bends in sheet metal are manufactured using sheet metal brakes.
Select a hard edge bend face flange face or 3d solid entire model.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
This is due to excessive localized stresses from the work hardening forces imposed on the metal.
When designing parts for laser cutting one should not make holes smaller than the thickness of the material.
Bend reliefs in sheet metal.
In sheet metal a bend relief is an incision cut along the sides of a planned bend.
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.
