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 may have sharp corners but designing a fillet of the material s thickness will make parts more cost effective. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend. If you select rectangular or obround specify the relief ratio. Right click the sheet metal feature in the featuremanager design tree and select edit feature.
A 1 degree tolerance on all bend angles. Relief cuts help parts avoid overhangs and tearing at bends. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
Bend relief synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. If it is ok for the metal to rip the minimum bend relief is zero. Bends in sheet metal are manufactured using sheet metal brakes.
Not shown scroll down in property manager is an auto relief setting that controls how corners and relief cuts are handled. 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. To change the type of relief cut for all bends.
