Sheet Metal Bend Relief

Select a hard edge bend face flange face or 3d solid entire model.

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. The bigger the bend relief the easier it is to align over the end of the tooling. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. Improper bending of sheet metal can cause material flow problems in soft material and fracturing in hard materials.

In sheet metal a bend relief is an incision cut along the sides of a planned bend. This article looks at two different tips associated with ensuring you have high quality sheet metal in finished products. One benefit of a bend relief is that it makes the part easier to produce. Though bend relief lengths and widths vary between projects they all share a common goal.

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. Select an item see the note below. Click the create relief tool button on the sheet metal ribbon tab.

Type smreliefcreate in the command bar. During the bending of sheet metal material around the bend tends to stretch and deform. If it is ok for the metal to rip the minimum bend relief is zero. Preventing tearing and part deformation during the bending process.

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.
