Bend Relief Sheet Metal

Click the create relief tool button on the sheet metal ribbon tab.

Bend relief sheet metal. During the bending of sheet metal material around the bend tends to stretch and deform. Bend relief synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. The default shape view is replaced by the relief view and editing tools. In sheet metal a bend relief is an incision cut along the sides of a planned bend.

To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. You can apply corner treatments to a folded sheet metal body that will persist in the flattened state. Select an item see the note below. To display the bend relief of a bend sheet metal shape.

Lack of proper bend reliefs may cause tearing of the material due to localized stresses. Another notch which we will call a relief notch is set back relieved a certain dimension from the edge. Select a hard edge bend face flange face or 3d solid entire model. Corner reliefs and bend transitions.

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. The bigger the bend relief the easier it is to align over the end of the tooling. Choose create relief in the sheet metal menu. This is to keep the material from fracturing while forming the metal.

Enter relief size by bend radius ratio or force bend reliefs auto auto. Bend relief and collars near pierced areas strengthen sheet metal parts. This article looks at two different tips associated with ensuring you have high quality sheet metal in finished products. Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.

Type smreliefcreate in the command bar. With the bend shape selected at the intellishape editing level click the handle toggle if necessary to switch to display of the bend relief tools. 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.

Though bend relief lengths and widths vary between projects they all share a common goal. The flange which does not have relief will result in a greater amount of distortion or tearing of the adjacent material. Preventing tearing and part deformation during the bending process. If it is ok for the metal to rip the minimum bend relief is zero.

Sometimes this notch is used for parts with a large bend radius. 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. You can use the following corner treatment types.
