Relief Sheet Metal

Bend reliefs in sheet metal.

Relief sheet metal.

When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. Bends in sheet metal are manufactured using sheet metal brakes. See the picture on the side for an example.

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. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. Sheet metal related searches. This is due to excessive localized stresses from the work hardening forces imposed on the metal.

Select a hard edge bend face flange face or 3d solid entire model. Choose create relief in the sheet metal menu. A 1 degree tolerance on all bend angles. Under corners click collect all corners to list all corners in the sheet metal body.

The corner relief is applied at the common intersection point of the bend lines. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. Enter relief size by bend radius ratio or force bend reliefs. The model must have three bends where the bend lines meet.

In general a minimum bend relief is equal to the material thickness plus the inside bend radius. You can add a corner relief to a single sheet metal body. Though bend relief lengths and widths vary between projects they all share a common goal. Similarly insufficient bend radius may lead to brittle fracture failure of the sheet metal.

Creates a corner relief where three bends meet at one common point. Creates a corner relief where two bends meet. Select an item see the note below. Do one of the following.

Click corner relief sheet metal toolbar or insert sheet metal corner relief. In the corner relief propertymanager under scope select the sheet metal body to which to apply the corner relief. Click insert sheet metal corner relief. Each corner of the t is at risk of tearing if the relevant line segment is bent without proper bend relief.

In sheet metal a bend relief is an incision cut along the sides of a planned bend. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
