METALWORK PROJECTS
PRODUCTION OF VARIOUS OBJECTS USING SIMPLE METALWORK MACHINES AND TOOLS
Sheet metal work and forging are two aspects of metal work leading to the production of various articles. The work is to be carried out in various stages. The first stage is shape development.
Shape development involves drawing out a pattern from which the article is produced. To mark out the required lengths, widths, angles and curves on metals certain tools are needed e.g. steel rule, caliper protractor centre punch etc.
The outline of the article is transferred by measurement on the flat metal sheet using the marking out tool; e.g. scriber, try square odd leg caliper etc.
TOOLS AND CUTTING
Different kinds of cutting tools can be used to cut out different shapes. These include:
(i) Chisel
(ii) Set snips
(iii) Bench shear
(iv) Hacksaw
Each tool is selected on the basis of two factors: the thickness of the metal to be cut and the shape to be cut.
FILES AND FILING
Filing operation on metal is the process of removing excess metal on a metal.
