Relief Cut Sheet Metal

Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending.

Relief cut sheet metal.

Relief cuts help parts avoid overhangs and tearing at. It obviously won t accept it because i am not doing it right. 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.

Sheet metal parts may have sharp corners but designing a fillet of the material s thickness will make parts more cost effective. Please take a look at the picture i m hopeful someone who works with sheet metal commonly will enjoy the kudos and. 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. Bend 2 shows a rectangular relief cut into the part the depth of the relief should be greater than the radius of the bend.

Sheet metal relief cut need to lay a flat pattern of a sheet metal part with a flange with a cut because it is not full length of the original face. Bend 1 shows a a tear relief. When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
