Sheet metal is simply metal formed into thin and flat pieces. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material.
Thicknesses can vary significantly, although extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.
Sheet metal is available as flat pieces or as a coiled strip. The coils are formed by running a continuous sheet of metal through a roll slitter.
There are many different metals that can be made into sheet metal, such as: Aluminum, brass, copper, steel, tin, nickel and titanium. Sheet metal has applications in car bodies, airplane wings, medical tables, roofs for building and many other things.
The data presented here came from a MTI Engineer experienced in welding and sheetmetal operations that has performed many time studies in this area.
1. Select "Average Gage Number"
The thickness of the sheet metal is called its gage. The gauge of sheet metal ranges from 36 gage to 3 gage. The higher the gage, the thinner the metal is. If you don't know the gage number, select 16 (.0598) from the list for now. The actual decimal size will appear on the next line. You can then go back and reselect until the decimal size you want appears on the screen.
2. Input "Box Height"
3. Input "Box Width"
4. Input "Box Depth"
5. Input "# of Drawers"
The Cut Length of the part is calculated. This length will be cut by a Laser Beam that will cut out any shape and size required on this part. An example would be a window cut out of the center of this part. The peripheral of that window would be included as part of the "Cut Length". The peripheral of the whole box shape would be part of the total cut length. Holes and slots are not.
