Bend relief is the notch that needs to be created for sheet metal bending.
Bending relief for sheet metal.
Though bend relief lengths and widths vary between projects they all share a common goal.
Do one of the following.
Bend relief and collars near pierced areas strengthen sheet metal parts.
See the picture on the side for an example.
Type smreliefcreate in the command bar.
The force must exceed the material s yield strength to achieve a plastic deformation.
Similarly insufficient bend radius may lead to brittle fracture failure of the sheet metal.
Quick video about bend radius watch more tech tip videos bend radii minimum bend sizes.
Click the create relief tool button on the sheet metal ribbon tab.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.
Preventing tearing and part deformation during the bending process.
Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending.
Protocase tech tip video.
Bending is one of the most common sheet metal fabrication operations.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
For better clarity see the picture below.
This shape can be visualized as bending one line segment in a t to the maximum depth permitted.
Commonly used equipment include box and pan brakes brake presses and other specialized machine presses typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.
Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal.

For better clarity see the picture below.
Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.
Bend radii minimum bend sizes.
3d cad files are converted into machine code which controls a machine to precisely cut and form the sheets into the final part.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
In sheet metal a bend relief is an incision cut along the sides of a planned bend.
This is done through the application of force on a workpiece.
The flange which does not have relief will result in a greater amount of distortion or tearing of the adjacent material.
Choose create relief in the sheet metal menu.
Select a hard edge bend face flange face or 3d solid entire model.
