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.
Relief sheet metal.
Choose create relief in the sheet metal menu.
Click the create relief tool button on the sheet metal ribbon tab.
In sheet metal a bend relief is an incision cut along the sides of a planned bend.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.
The corner relief is applied at the common intersection point of the bend lines.
Type smreliefcreate in the command bar.
Click insert sheet metal corner relief.
Similarly insufficient bend radius may lead to brittle fracture failure of the sheet metal.
Creates a corner relief where three bends meet at one common point.
Enter relief size by bend radius ratio or force bend reliefs.
Bends in sheet metal are manufactured using sheet metal brakes.
Select an item see the note below.
Bend relief and collars near pierced areas strengthen sheet metal parts.
The model must have three bends where the bend lines meet.
When designing parts for laser cutting one should not make holes smaller than the thickness of the material.
Preventing tearing and part deformation during the bending process.
This is due to excessive localized stresses from the work hardening forces imposed on the metal.
You can add a corner relief to a single sheet metal body.
A 1 degree tolerance on all bend angles.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
Do one of the following.
Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
Though bend relief lengths and widths vary between projects they all share a common goal.
See the picture on the side for an example.
Creates a corner relief where two bends meet.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.
Each corner of the t is at risk of tearing if the relevant line segment is bent without proper bend relief.
Under corners click collect all corners to list all corners in the sheet metal body.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
