Relief Ratio Sheet Metal

7 only affects the relief within a narrow margin.

Relief ratio sheet metal.

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. The higher the value the larger the size of the relief cut added during insertion of bends. When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.

The length ratio 3 2 fig. The value of the relief ratio must be between 0 05 and 2 0. User can configure the ratio based on the material. When designing parts for laser cutting one should not make holes smaller than the thickness of the material.

The value of the relief ratio must be between 0 05 and 2 0. D relief ratio part thickness the bend region is represented by the dark gray area of the diagram. Sheet metal in solidworks sheet metal parts are generally used as enclosures for components or to provide support to other. The higher the value the larger the size of the relief cut added during insertion of bends.

Auto relief types rectangular tear obround using understanding auto relief ratio cases when relief not working. 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. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. In the propertymanager under auto relief change the type of relief cut.

If you select rectangular or obround specify the relief ratio. Bends in sheet metal are manufactured using sheet metal brakes. 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. The value of the relief ratio must be between 0 05 and 2 0.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. Ratios are configured for the hard material condition. A 1 degree tolerance on all bend angles. This check computes inside bend radius and checks the ratio of bend radius to sheet thickness.

When starting a sheet metal part by creating a base flange feature one of the initial parameters along with sheet metal gauge and bend allowance are the auto relief settings. Right click the sheet metal feature in the featuremanager design tree and select edit feature.
