Bend Relief In Sheet Metal

Use the corner relief propertymanager to apply corner treatments to a folded sheet metal body that persist in the flattened state.

Bend relief in sheet metal.

First utilize minimal bend radius of internal bend radius equal to material thickness. Select a hard edge bend face flange face or 3d solid entire model. Enter relief size by bend radius ratio or force bend reliefs auto. One benefit of a bend relief is that it makes the part easier to produce.

Click the create relief tool button on the sheet metal ribbon tab. Type smreliefcreate in the command bar. Bend reliefs in sheet metal. The gap between the bend and surrounding material allows us to shape the sheet in the press brake cleanly eliminating cracking and tearing.

There are two things that can be done to reduce the risk of sheet metal tearing. A bend relief creates space between the bent and unbent surfaces so that the edge of the sheet metal is perpendicular to the bend itself. Select an item see the note below. Parent topic using sheet metal tools search corner reliefs and bend transitions in the solidworks knowledge base.

You should also incorporate the use of bend relief cuts with a thickness of at least the thickness of the material with strong preference for bend relief cuts of a thickness. 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.
