Sheet Metal Bend Relief

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.

Sheet metal bend relief.

In general a minimum bend relief is equal to the material thickness plus the inside bend radius. We would like to show you a description here but the site won t allow us. Select an item see the note below. Enter relief size by bend radius ratio or force bend reliefs.

The gap between the bend and surrounding material allows us to shape the sheet in the press brake cleanly eliminating cracking and tearing. 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. One benefit of a bend relief is that it makes the part easier to produce. Avoid large sheet metal parts with small bent flanges.

Select a hard edge bend face flange face or 3d solid entire model. Click the create relief tool button on the sheet metal ribbon tab. Do one of the following. 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.

Type smreliefcreate in the command bar. Choose create relief in the sheet metal menu. Bend relief and collars near pierced areas strengthen sheet metal parts. 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.

Design for manufacturability sheet metal guidelines bends for the ease of manufacturing multiple bends on the same plane should occur in the same direction. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. Bends in sheet metal are manufactured using sheet metal brakes. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.

Relief height is generally kept greater than two times of sheet thickness plus bend radius. 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. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
