Sheet Metal Bend Relief

Type smreliefcreate in the command bar.

Sheet metal bend relief.

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. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.

Click the create relief tool button on the sheet metal ribbon tab. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. 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.

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. Choose create relief in the sheet metal menu. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm. Select a hard edge bend face flange face or 3d solid entire model.

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 and collars near pierced areas strengthen sheet metal parts. Avoid large sheet metal parts with small bent flanges. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.

If it is ok for the metal to rip the minimum bend relief is zero. Relief height is generally kept greater than two times of sheet thickness plus bend radius. A 1 degree tolerance on all bend angles. Select an item see the note below.

Bends in sheet metal are manufactured using sheet metal brakes. One benefit of a bend relief is that it makes the part easier to produce. 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. Do one of the following.

Design for manufacturability sheet metal guidelines bends for the ease of manufacturing multiple bends on the same plane should occur in the same direction.
