Sheet Metal Bending Corner Relief

The final bend radius will be.

Sheet metal bending corner relief.

You can also specify the relief size and whether to apply auto mitering. You can specify the corner relief shape for a 2 or 3 bend corner. Corners give you another option with the close 2 bend corner tool. One benefit of a bend relief is that it makes the part easier to produce.

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. If it is ok for the metal to rip the minimum bend relief is zero. Sheet metal related searches.

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 corner relief is applied at the common intersection point of the bend lines. Centered on bend lines option. This allows you to take either of the corner types mentioned above and close the gap between the flanges.

The corner tab lets you override default parameters in the sheet metal styles dialog box. Ratio to thickness option. Understanding ironcad s mehtodology compared to conventional systems. Relief height is generally kept greater than two times of sheet thickness plus bend radius.

For the obround relief the bend lines intersection meets at the center of the slot. When bending a piece of sheet metal the residual stresses in the material will cause the sheet to springback slightly after the bending operation. See an explanation of ironcad s unique design methodology. In general a minimum bend relief is equal to the material thickness plus the inside bend radius.

Under corners click collect all corners to list all corners in the sheet metal body. In addition a. 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.

Creates a corner relief where two bends meet. Creates a corner relief where three bends meet at one common point. The model must have three bends where the bend lines meet exactly at one point. This option is straight forward.

Corner reliefs and junctions. 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. Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner. 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 you list multiple corners you can specify multiple corner relief treatments.
