6 shows when the ratio to thickness is used in a obround relief the width ratio has more influence on the shape of the relief than the length ratio.
Relief ratio sheet metal.
The higher the value the larger the size of the relief cut added during insertion of bends.
If you select rectangular or obround specify the relief ratio.
A 1 degree tolerance on all bend angles.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.
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.
User can configure the ratio based on the material.
Auto relief types rectangular tear obround using understanding auto relief ratio cases when relief not working.
In the propertymanager under auto relief change the type of relief cut.
Bends in sheet metal are manufactured using sheet metal brakes.
Examples of i tear ii obround and iii rectangle.
163 solidworks sheet metal tutorial.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
The higher the value the larger the size of the relief cut added during insertion of bends.
7 only affects the relief within a narrow margin.
The value of the relief ratio must be between 0 05 and 2 0.
The length ratio 3 2 fig.
The value of the relief ratio must be between 0 05 and 2 0.
For a 3 width ratio when the part is 1 mm in thickness the width of the slot will be 3 mm.
The higher the value the larger the size of the relief cut added during insertion of bends.
Sheet metal in solidworks sheet metal parts are generally used as enclosures for components or to provide support to other.
This check computes inside bend radius and checks the ratio of bend radius to sheet thickness.
Ratios are configured for the hard material condition.
D relief ratio part thickness the bend region is represented by the dark gray area of the diagram.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
Right click the sheet metal feature in the featuremanager design tree and select edit feature.
