a) Use and utilize sheet metal fabrication tools. b) Perform safety procedures during sheet metal working in the workshop. c) Describe the acquired knowledge and skills through log book.
2.0 INTRODUCTION
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.
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.
The thickness of the sheet metal is called its gauge. The gauge of sheet metal ranges from
30 gauge to about 8 gauge. The larger the gauge number, the thinner the metal.
There are many different metals that can be made into sheet metal, such as aluminum,
brass, copper, steel, tin, nickel and titanium. For decorative uses, important sheet metals
include silver, gold, and platinum (platinum sheet metal is also utilized as a catalyst.)
Sheet metal has applications in car bodies, airplane wings, medical tables, roofs for
buildings and many other things. Sheet metal of iron and other materials with high
magnetic permeability, also known as laminated steel cores, has applications in
transformers and electric machines. Historically, an important use of sheet metal was in
plate armor worn by cavalry, and sheet metal continues to have many decorative uses,
including in horse tack.
Process Characteristics:
There are three major categories of sheet metal processes. These are cutting, bending and
drawing. Cutting is use to separate larger sheets into smaller pieces, to cut out a perimeter
or make holes in a part. Sheet metal parts are formed into their shapes using bending
drawing process. Following sections discuss each process.
Hemming and seaming
Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. A hem is when the edge is rolled flush to itself, while a seam joins the edges of two materials.

Hems are commonly used to reinforce an edge, hide burrs and rough edges, and improve appearance.
Seams are commonly used in the food industry on canned goods, on amusement park cars, and in the automotive industry.
