Sheet Metal Bending Corner Relief

Relief height is generally kept greater than two times of sheet thickness plus bend radius.

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. Corner reliefs and junctions. One benefit of a bend relief is that it makes the part easier to produce. This allows you to take either of the corner types mentioned above and close the gap between the flanges.

However if you rework poor sheet metal parts you may find it useful to create corner and bend reliefs with the dedicated tools. Understanding ironcad s mehtodology compared to conventional systems. Bend reliefs in sheet metal. 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. 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. Corners give you another option with the close 2 bend corner tool. When bending a piece of sheet metal the residual stresses in the material will cause the sheet to springback slightly after the bending operation.

Sheet metal related searches. This option is straight forward. Creates a corner relief where three bends meet at one common point. 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. The final bend radius will be. Creates a corner relief where two bends meet. The corner tab lets you override default parameters in the sheet metal styles dialog box.

In addition a. Override sheet metal style settings for corner shape and relief. Corner fillets relief cuts. You can specify the corner relief shape for a 2 or 3 bend corner.

To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. Under corners click collect all corners to list all corners in the sheet metal body. See an explanation of ironcad s unique design methodology. 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.

Ratio to thickness option. If you list multiple corners you can specify multiple corner relief treatments. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. You can also specify the relief size and whether to apply auto mitering.

The model must have three bends where the bend lines meet exactly at one point.
