Relief Sheet Metal

Enter relief size by bend radius ratio or force bend reliefs.

Relief sheet metal. Similarly insufficient bend radius may lead to brittle fracture failure of the sheet metal. Each corner of the t is at risk of tearing if the relevant line segment is bent without proper bend relief. Click the create relief tool button on the sheet metal ribbon tab. Though bend relief lengths and widths vary between projects they all share a common goal.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. Choose create relief in the sheet metal menu. Do one of the following. In sheet metal a bend relief is an incision cut along the sides of a planned bend.

Select a hard edge bend face flange face or 3d solid entire model. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. Bends in sheet metal are manufactured using sheet metal brakes. See the picture on the side for an example.

Bend reliefs in sheet metal. Select an item see the note below. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. Under corners click collect all corners to list all corners in the sheet metal body.

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. Click corner relief sheet metal toolbar or insert sheet metal corner relief. This is due to excessive localized stresses from the work hardening forces imposed on the metal.

Sheet metal related searches. Creates a corner relief where two bends 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. Creates a corner relief where three bends meet at one common point.

The model must have three bends where the bend lines meet. Click insert sheet metal corner relief. The corner relief is applied at the common intersection point of the bend lines. Preventing tearing and part deformation during the bending process.

A 1 degree tolerance on all bend angles. In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
