To display the bend relief of a bend sheet metal shape.
Bend relief sheet metal.
Choose create relief in the sheet metal menu.
Sometimes this notch is used for parts with a large bend radius.
During the bending of sheet metal material around the bend tends to stretch and deform.
The flange which does not have relief will result in a greater amount of distortion or tearing of the adjacent material.
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.
Lack of proper bend reliefs may cause tearing of the material due to localized stresses.
Bend relief synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
Another notch which we will call a relief notch is set back relieved a certain dimension from the edge.
The bigger the bend relief the easier it is to align over the end of the tooling.
Enter relief size by bend radius ratio or force bend reliefs auto auto.
Preventing tearing and part deformation during the bending process.
Normally that dimension is called out on the blueprint.
Select a hard edge bend face flange face or 3d solid entire model.
Select an item see the note below.
You can view how the corner treatment impacts the folded sheet metal body and how it carries over to the flat pattern.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
If it is ok for the metal to rip the minimum bend relief is zero.
This article looks at two different tips associated with ensuring you have high quality sheet metal in finished products.
Improper bending of sheet metal can cause material flow problems in soft material and fracturing in hard materials.
You can use the following corner treatment types.
Bend relief and collars near pierced areas strengthen sheet metal parts.
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.
Type smreliefcreate in the command bar.
In sheet metal a bend relief is an incision cut along the sides of a planned bend.
Click the create relief tool button on the sheet metal ribbon tab.
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.
Corner reliefs and bend transitions.
You can apply corner treatments to a folded sheet metal body that will persist in the flattened state.
This is to keep the material from fracturing while forming the metal.
Though bend relief lengths and widths vary between projects they all share a common goal.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
