Sheet Metal Bend Relief

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

Sheet metal bend relief.

Type smreliefcreate in the command bar. Lack of proper bend reliefs may cause tearing of the material due to localized stresses. Choose create relief in the sheet metal menu. Improper bending of sheet metal can cause material flow problems in soft material and fracturing in hard materials.

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. 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. 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. During the bending of sheet metal material around the bend tends to stretch and deform.

Though bend relief lengths and widths vary between projects they all share a common goal. Preventing tearing and part deformation during the bending process. The bigger the bend relief the easier it is to align over the end of the tooling. One benefit of a bend relief is that it makes the part easier to produce.

If it is ok for the metal to rip the minimum bend relief is zero.
