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