The width of the relief should be a material thickness or greater preferably a material thickness 1 64.
Relief cut sheet metal.
If you select rectangular or obround specify the relief ratio.
You can add a corner relief to a single sheet metal body.
Sheet metal parts may have sharp corners but designing a fillet of the material s thickness will make parts more cost effective.
To change the type of relief cut for all bends.
Relief cuts help parts avoid overhangs and tearing at bends.
One benefit of a bend relief is that it makes the part easier to produce.
We would like to show you a description here but the site won t allow us.
Bend 1 shows a a tear relief.
If it is ok for the metal to rip the minimum bend relief is zero.
4 forming near holes when a bend is made too close to a hole the hole may become deformed.
Bend relief and collars near pierced areas strengthen sheet metal parts.
Bend relief synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending.
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.
In the corner relief propertymanager under scope select the sheet metal body to which to apply the corner relief.
In the propertymanager under auto relief change the type of relief cut.
Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.
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.
Bend 2 shows a rectangular relief cut into the part the depth of the relief should be greater than the radius of the bend.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
Right click the sheet metal feature in the featuremanager design tree and select edit feature.
