Relief Cut Sheet Metal

Relief cuts help parts avoid overhangs and tearing at bends.

Relief cut sheet metal.

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. The width of the relief should be the material thickness or greater. Bend relief and collars near pierced areas strengthen sheet metal parts.

The width of the relief should be a material thickness or greater preferably a material thickness 1 64. Right click the sheet metal feature in the featuremanager design tree and select edit feature.
