Sheet Metal Bend Relief

Preventing tearing and part deformation during the bending process.

Sheet metal bend relief.

In general a minimum bend relief is equal to the material thickness plus the inside bend radius. Choose create relief in the sheet metal menu. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. 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.

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. Select a hard edge bend face flange face or 3d solid entire model. This article looks at two different tips associated with ensuring you have high quality sheet metal in finished products. 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.

To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. In sheet metal a bend relief is an incision cut along the sides of a planned bend. The bigger the bend relief the easier it is to align over the end of the tooling. If it is ok for the metal to rip the minimum bend relief is zero.

Type smreliefcreate in the command bar. Lack of proper bend reliefs may cause tearing of the material due to localized stresses. Though bend relief lengths and widths vary between projects they all share a common goal. Improper bending of sheet metal can cause material flow problems in soft material and fracturing in hard materials.
