How To Make A Cross Break In Sheet Metal

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 make a cross break in sheet metal.

Most common are doors. Coining one of the three types of bending for sheet metal where the punch penetrates into the sheet metal under high tonnage forming a consistent bend. 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. A question we sometimes get in the solidworks sheet metal course is how to insert a 3d cross break.

How to bend sheet metal without a brake. 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. Cross breaks are most commonly in an x shape forming a slight pyramid shape in the metal without overly distorting it. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools.

A cross break is simply a diagonal bend very slight bend from two corners of a part. Box bending the process of bending a 4 sided sheet metal box. Right now the unfolding is the last thing that happens in a sheet metal compute. The cross break is not a geometric entity and does not alter the geometry of the part.

This was done by two cross breaks. So we need to add the capability to reorder the flat pattern and add things after it that are not meant to be flattened. The crossing ridges stiffen the face of the metal and help prevent is from buckling under a load. They are typically used on relatively large flat ares to keep the panel from bowing easily.

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. The cross break command lets you insert a graphical representation of a cross break in a sheet metal part. You may see an x on the front of a sheet metal door or panel from corner to corner.
