Sheet Metal Bend Relief

In general a minimum bend relief is equal to the material thickness plus the inside bend radius.

Sheet metal bend relief.

This article looks at two different tips associated with ensuring you have high quality sheet metal in finished products. If it is ok for the metal to rip the minimum bend relief is zero. In sheet metal a bend relief is an incision cut along the sides of a planned bend. 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. The bigger the bend relief the easier it is to align over the end of the tooling. Type smreliefcreate in the command bar. Choose create relief in the sheet metal menu.

Though bend relief lengths and widths vary between projects they all share a common goal. Select a hard edge bend face flange face or 3d solid entire model. Improper bending of sheet metal can cause material flow problems in soft material and fracturing in hard materials. Click the create relief tool button on the sheet metal ribbon tab.

Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. 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. Preventing tearing and part deformation during the bending process.

Lack of proper bend reliefs may cause tearing of the material due to localized stresses.
