You can specify the corner relief shape for a 2 or 3 bend corner.
Sheet metal bending corner relief.
Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.
In addition a.
Bend reliefs in sheet metal.
Override sheet metal style settings for corner shape and relief.
Understanding ironcad s mehtodology compared to conventional systems.
Centered on bend lines option.
When you create a flange using the smflangeedge command adjacent to a bend edge a corner relief is created automatically in the corner where the three flanges meet.
Relief height is generally kept greater than two times of sheet thickness plus bend radius.
The corner relief is applied at the common intersection point of the bend lines.
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.
If it is ok for the metal to rip the minimum bend relief is zero.
Corner reliefs and junctions.
This option is straight forward.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
One benefit of a bend relief is that it makes the part easier to produce.
See an explanation of ironcad s unique design methodology.
When bending a piece of sheet metal the residual stresses in the material will cause the sheet to springback slightly after the bending operation.
The final bend radius will be.
However if you rework poor sheet metal parts you may find it useful to create corner and bend reliefs with the dedicated tools.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
You can also specify the relief size and whether to apply auto mitering.
Ratio to thickness option.
This allows you to take either of the corner types mentioned above and close the gap between the flanges.
Sheet metal related searches.
The corner tab lets you override default parameters in the sheet metal styles dialog box.
Corners give you another option with the close 2 bend corner tool.
Corner fillets relief cuts.
Creates a corner relief where three bends meet at one common point.
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.
For the obround relief the bend lines intersection meets at the center of the slot.
If you list multiple corners you can specify multiple corner relief treatments.
The model must have three bends where the bend lines meet exactly at one point.
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.
