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