A cross break is simply a diagonal bend very slight bend from two corners of a part.
How to make a cross break in sheet metal.
You add it to provide the information needed to create the cross break during manufacturing.
Most common are doors.
Right now the unfolding is the last thing that happens in a sheet metal compute.
Cross breaks are most commonly in an x shape forming a slight pyramid shape in the metal without overly distorting it.
The functionality seems to be there in the solidworks cross break command on the sheet metal toolbar but upon inspection the cross break it inserts is merely cosmetic.
Box bending the process of bending a 4 sided sheet metal box.
Cross break light bends added to sheet metal in order to stiffen its surface.
They are typically used on relatively large flat ares to keep the panel from bowing easily.
A cross break in sheet metal is when multiple obtuse bend angles of approximately 170 are made across a flat section thin metal.
How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools.
To form lightweight parts that must avoid flexing cross break bending uses standard bending tools to make an x shaped pair of very shallow bends across the middle of the panel.
So we need to add the capability to reorder the flat pattern and add things after it that are not meant to be flattened.
A question we sometimes get in the solidworks sheet metal course is how to insert a 3d cross break.
The crossing ridges stiffen the face of the metal and help prevent is from buckling under a load.
You may see an x on the front of a sheet metal door or panel from corner to corner.
This was done by two cross breaks.
Only a few degrees of bending angle are needed because the cross break pattern allows thin panels to stay relatively flat but still benefit from the increased rigidity that bending tensioning the sheet provides.
How to bend sheet metal without a brake.
I believe that is what has been discussed as the preferred solution but the issue is that this cross break has to happen after the unfolding.
