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