Relief Cuts In Sheet Metal

This same tool can be used to make a flat piece of sheet metal that one would use to add edge flanges and other useful sheet metal features.

Relief cuts in sheet metal.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. 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. A 1 degree tolerance on all bend angles.

Not shown scroll down in property manager is an auto relief setting that controls how corners and relief cuts are handled. Sheet metal parts may have sharp corners but designing a fillet of the material s thickness will make parts more cost effective. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. Bends in sheet metal are manufactured using sheet metal brakes.

If you select rectangular or obround specify the relief ratio. To change the type of relief cut for all bends. One benefit of a bend relief is that it makes the part easier to produce. Bend relief synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.

Right click the sheet metal feature in the featuremanager design tree and select edit feature. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. If it is ok for the metal to rip the minimum bend relief is zero.
