Creates a corner relief where two bends meet.
Sheet metal bending corner relief.
This option is straight forward.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
When the option centered on bend lines is checked the center of the square and circular reliefs match the intersection of the bend lines fig.
Corners give you another option with the close 2 bend corner tool.
If you list multiple corners you can specify multiple corner relief treatments.
You can also specify the relief size and whether to apply auto mitering.
For the obround relief the bend lines intersection meets at the center of the slot.
Override sheet metal style settings for corner shape and relief.
The corner relief is applied at the common intersection point of the bend lines.
The corner tab lets you override default parameters in the sheet metal styles dialog box.
One benefit of a bend relief is that it makes the part easier to produce.
Corner reliefs and junctions.
Due to this elastic recovery it is necessary to over bend the sheet a precise amount to achieve the desired bend radius and bend angle.
When bending a piece of sheet metal the residual stresses in the material will cause the sheet to springback slightly after the bending operation.

Bend reliefs in sheet metal.
Centered on bend lines option.
Under corners click collect all corners to list all corners in the sheet metal body.
This allows you to take either of the corner types mentioned above and close the gap between the flanges.
In addition a.
Creates a corner relief where three bends meet at one common point.
Corner fillets relief cuts.
The final bend radius will be.
Understanding ironcad s mehtodology compared to conventional systems.
However if you rework poor sheet metal parts you may find it useful to create corner and bend reliefs with the dedicated tools.
Relief height is generally kept greater than two times of sheet thickness plus bend radius.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
You can specify the corner relief shape for a 2 or 3 bend corner.
Ratio to thickness option.
If you use the close 2 bend corner tool you can take the two corner types shown above and they will look like the closed corner shown below with the flat pattern to the right.
Sheet metal related searches.
The model must have three bends where the bend lines meet exactly at one point.
If it is ok for the metal to rip the minimum bend relief is zero.
