The crossing ridges stiffen the face of the metal and help prevent is from buckling under a load.
Purpose of cross break in sheet metal.
A question we sometimes get in the solidworks sheet metal course is how to insert a 3d cross break.
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.
Cross breaks are most commonly in an x shape forming a slight pyramid shape in the metal without overly distorting it.
The cross break is not a geometric entity and does not alter the geometry of the part.
A brake is a metalworking machine that allows the bending of sheet metal a cornice brake only allows for simple bends and creases while a box and pan brake also allows one to form box and pan shapes.
How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools.

How to bend sheet metal without a brake.
Here are some ways to increase the structural strength of flat sheet stock without adding gussets or increasing the weight of the product.
Crowning is controlled on modern brakes with internal hydraulic systems which can help equalize pressure.
Sheet metal has a high strength to weight ratio and good malleability that can provide form and structure to products but because it is flat and bends easily it doesn t always work.
You add it to provide the information needed to create the cross break during manufacturing.
Crowning the deflection along a bend due to the tooling or brake not being able to apply equal tonnage along the bend.
A cross break in sheet metal is when multiple obtuse bend angles of approximately 170 are made across a flat section thin metal.
Cross braking is a technique performed using a press brake.
