Sheet Metal Relief

For example if you make a partial flange as above using all the defaults the software makes relief cuts at the end of the bends as shown to the right.

Sheet metal relief.

This is to keep the material from fracturing while forming the metal. To create a relief locally you can select one or two hard edges one or two bends or a bend and a hard edge. The selected items can be a 3d solid with sheet metal features a face or a hard edge of the solid. As per sheet metal design thumb rules the depth of bend relief should be greater than or equal to the inside bend radius of the bend and the width of the bend relief should be the same as the sheet metal thickness or more.

Normally that dimension is called out on the blueprint. Another notch which we will call a relief notch is set back relieved a certain dimension from the edge. Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner. Extrude hole size position guidelines creating an extruded hole using a punching process requires extreme pressure force.

Though bend relief lengths and widths vary between projects they all share a common goal. You can add a corner relief to a single sheet metal body. Under corners click collect all corners to list all corners in the sheet metal body. Relief height is generally kept greater than two times of sheet thickness plus bend radius.

The flange which does not have relief will result in a greater amount of distortion or tearing of the adjacent material. The president of a fort myers roofing company is facing 30 years in federal prison after being charged with falsely acquiring 2 million in covid 19 relief funds and using nearly 700 000 of it to. Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on. One benefit of a bend relief is that it makes the part easier to produce.

Preventing tearing and part deformation during the bending process. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. In the corner relief propertymanager under scope select the sheet metal body to which to apply the corner relief. During the bending of sheet metal material around the bend tends to stretch and deform.

If a 3d solid is selected the command recognizes the places where corner or bend reliefs are needed and creates them automatically. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. Click corner relief sheet metal toolbar or insert sheet metal corner relief.
