Relief Cut Sheet Metal

It obviously won t accept it because i am not doing it right.

Relief cut sheet metal. When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear. 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. Then i would have to come back and draw a sketch on top of the sheet metal where there is not a relief cut and add another thickness of sheet metal. 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.

Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word. Bend 2 shows a rectangular relief cut into the part the depth of the relief should be greater than the radius of the bend. Relief cuts help parts avoid overhangs and tearing at. The width of the relief should be the material thickness or greater.

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. Bend 1 shows a a tear relief. Please take a look at the picture i m hopeful someone who works with sheet metal commonly will enjoy the kudos and.
