A 1 degree tolerance on all bend angles.
Sheet metal bend relief.
Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
Choose create relief in the sheet metal menu.
One benefit of a bend relief is that it makes the part easier to produce.
A bend relief creates space between the bent and unbent surfaces so that the edge of the sheet metal is perpendicular to the bend itself.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
Select a hard edge bend face flange face or 3d solid entire model.
Sheet metal bend relief modify a bend relief the small cut made where the bend end meets a free edge and by specifying a shape and either a depth and relief width scale or specific bend relief depth.
The gap between the bend and surrounding material allows us to shape the sheet in the press brake cleanly eliminating cracking and tearing.
Click the create relief tool button on the sheet metal ribbon tab.
Bends in sheet metal are manufactured using sheet metal brakes.
Design for manufacturability sheet metal guidelines bends for the ease of manufacturing multiple bends on the same plane should occur in the same direction.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
When designing parts for laser cutting one should not make holes smaller than the thickness of the material.
If it is ok for the metal to rip the minimum bend relief is zero.
You are also able to select to extend the bend relief in the opposite direction in the case of a flange for example illustrations below.
Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.
We would like to show you a description here but the site won t allow us.
Relief height is generally kept greater than two times of sheet thickness plus bend radius.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
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.
Avoid large sheet metal parts with small bent flanges.
Bend relief and collars near pierced areas strengthen sheet metal parts.
Select an item see the note below.
Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.
Type smreliefcreate in the command bar.
