In the propertymanager under auto relief change the type of relief cut.
Relief ratio sheet metal.
Type smreliefcreate in the command bar.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.
The higher the value the larger the size of the relief cut added during insertion of bends.
Examples of i tear.
The value of the relief ratio must be between 0 05 and 2 0.
Bend radii minimum bend sizes.
This check computes inside bend radius and checks the ratio of bend radius to sheet thickness.
Sheet metal in solidworks sheet metal parts are generally used as enclosures for components or to provide support to other.
Right click the sheet metal feature in the featuremanager design tree and select edit feature.
User can configure the ratio based on the material.
Enter relief size by bend radius ratio or force bend reliefs.
The higher the value the larger the size of the relief cut added during insertion of bends.
Choose create relief in the sheet metal menu.
7 only affects the relief within a narrow margin.
If you select rectangular or obround specify the relief ratio.
Protocase tech tip video.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
Click the create relief tool button on the sheet metal ribbon tab.

Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending.
The length ratio 3 2 fig.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
Select an item see the note below.
Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.
Ratios are configured for the hard material condition.
The value of the relief ratio must be between 0 05 and 2 0.
The width of the relief cut and the depth it extends past the bend will be determined by relief ratio part thickness.
Do one of the following.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
Once the base flange feature is created this setting will be.
For a 3 width ratio when the part is 1 mm in thickness the width of the slot will be 3 mm.
Select a hard edge bend face flange face or 3d solid entire model.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to tear depending on the geometry.
