Relief Sheet Metal

Bend relief and collars near pierced areas strengthen sheet metal parts.

Relief sheet metal.

Click insert sheet metal corner relief. Enter relief size by bend radius ratio or force bend reliefs. Bends in sheet metal are manufactured using sheet metal brakes. In the corner relief propertymanager under scope select the sheet metal body to which to apply the corner relief.

Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. Do one of the following. The model must have three bends where the bend lines meet. 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.

This is due to excessive localized stresses from the work hardening forces imposed on the metal. You can add a corner relief to a single sheet metal body. See the picture on the side for an example. Click corner relief sheet metal toolbar or insert sheet metal corner relief.

The corner relief is applied at the common intersection point of the bend lines. When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear. Type smreliefcreate in the command bar. In general a minimum bend relief is equal to the material thickness plus the inside bend radius.

Preventing tearing and part deformation during the bending process. Click the create relief tool button on the sheet metal ribbon tab. Creates a corner relief where two bends meet. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.

Choose create relief in the sheet metal menu. Under corners click collect all corners to list all corners in the sheet metal body. 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.

When designing parts for laser cutting one should not make holes smaller than the thickness of the material. A 1 degree tolerance on all bend angles. Select an item see the note below. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.

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.
