You should also incorporate the use of bend relief cuts with a thickness of at least the thickness of the material with strong preference for bend relief cuts of a thickness equal to material thickness plus 1 64 inches.
Sheet metal corner relief design.
The selected items can be a 3d solid with sheet metal features a face or a hard edge of the solid.
First utilize minimal bend radius of internal bend radius equal to material thickness.
The resulting model faces are all nicely trimmed and all have appropriate corner relief in the flat pattern.
You can apply corner relief automatically to all corners or manually to individual sets of corners.
Click corner relief sheet metal toolbar.
Use the corner relief propertymanager to apply corner treatments to a folded sheet metal body that persist in the flattened state.
Do one of the following.
A 1 degree tolerance on all bend angles.
Extrude hole size position guidelines creating an extruded hole using a punching process requires extreme pressure force.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.
About corner relief use the corner relief tool to add relief to one or more corners of a sheet metal part.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
Depending on the types of parts that you design you may have to create additional sheet metal features.
There are two things that can be done to reduce the risk of sheet metal tearing.
Relief height is generally kept greater than two times of sheet thickness plus bend radius.
Figure 3 figure 4 figure 5 figure 6.
If a 3d solid is selected the command recognizes the places where corner or bend reliefs are needed and creates them automatically.
Rip corner relief and conversion creo creoparamet.
When designing parts for laser cutting one should not make holes smaller than the thickness of the material.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
To create a relief locally you can select one or two hard edges one or two bends or a bend and a hard edge.
Understanding corner relief design flexibility2 the contour flange is created using the auto miter option and the seven edge loop of the polygon is selected.
To open the corner relief propertymanager.
If it is ok for the metal to rip the minimum bend relief is zero.
When you add relief sheet metal sections are removed from the model.
