Bend Relief Sheet Metal

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.

Bend relief sheet metal.

Click the create relief tool button on the sheet metal ribbon tab. Choose create relief in the sheet metal menu. The bigger the bend relief the easier it is to align over the end of the tooling. Preventing tearing and part deformation during the bending process.

Enter relief size by bend radius ratio or force bend reliefs auto auto. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. One benefit of a bend relief is that it makes the part easier to produce. During the bending of sheet metal material around the bend tends to stretch and deform.

In sheet metal a bend relief is an incision cut along the sides of a planned bend. Lack of proper bend reliefs may cause tearing of the material due to localized stresses. Normally that dimension is called out on the blueprint. If it is ok for the metal to rip the minimum bend relief is zero.

This is to keep the material from fracturing while forming the metal. You can view how the corner treatment impacts the folded sheet metal body and how it carries over to the flat pattern. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. The flange which does not have relief will result in a greater amount of distortion or tearing of the adjacent material.

Select an item see the note below. Sometimes this notch is used for parts with a large bend radius. Corner reliefs and bend transitions. Though bend relief lengths and widths vary between projects they all share a common goal.

You can use the following corner treatment types. Bend relief synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. Bend relief and collars near pierced areas strengthen sheet metal parts. To display the bend relief of a bend sheet metal shape.

This article looks at two different tips associated with ensuring you have high quality sheet metal in finished products. As per sheet metal design thumb rules the depth of bend relief should be greater than or equal to the inside bend radius of the bend and the width of the bend relief should be the same as the sheet metal thickness or more. Type smreliefcreate in the command bar. You can apply corner treatments to a folded sheet metal body that will persist in the flattened state.

Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on. The default shape view is replaced by the relief view and editing tools. Select a hard edge bend face flange face or 3d solid entire model.
