Sheet Metal Bend Relief

Click the create relief tool button on the sheet metal ribbon tab.

Sheet metal bend relief.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. We would like to show you a description here but the site won t allow us. Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on. Relief height is generally kept greater than two times of sheet thickness plus bend radius.

In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm. One benefit of a bend relief is that it makes the part easier to produce. Do one of the following. Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.

Bends in sheet metal are manufactured using sheet metal brakes. Select an item see the note below. 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. Enter relief size by bend radius ratio or force bend reliefs.

Choose create relief in the sheet metal menu. Bend relief and collars near pierced areas strengthen sheet metal parts. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. In general a minimum bend relief is equal to the material thickness plus the inside bend radius.

Avoid large sheet metal parts with small bent flanges. 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. 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 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.

If it is ok for the metal to rip the minimum bend relief is zero. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. A 1 degree tolerance on all bend angles. Type smreliefcreate in the command bar.

To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
