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.

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. The gap between the bend and surrounding material allows us to shape the sheet in the press brake cleanly eliminating cracking and tearing. Bends in sheet metal are manufactured using sheet metal brakes. Avoid large sheet metal parts with small bent flanges.

Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on. One benefit of a bend relief is that it makes the part easier to produce. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.

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. Click the create relief tool button on the sheet metal ribbon tab. Do one of the following. Choose create relief in the sheet metal menu.

Select a hard edge bend face flange face or 3d solid entire model. A 1 degree tolerance on all bend angles. Bend relief and collars near pierced areas strengthen sheet metal parts. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm.

If it is ok for the metal to rip the minimum bend relief is zero. We would like to show you a description here but the site won t allow us. Type smreliefcreate in the command bar. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.

In general a minimum bend relief is equal to the material thickness plus the inside bend radius. Select an item see the note below. Relief height is generally kept greater than two times of sheet thickness plus bend radius. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.

When designing parts for laser cutting one should not make holes smaller than the thickness of the material.
