KEY WORDS: Aided, Interpret, Automatically, Identical

CAD= Computer aided design- its the process of designing using a computer.

CAM= Computer aided manufacture- using machine to make designs created

on a computer.

CNC Computer numerical control- This means a computer converts the

design produced by Computer Aided Design software (CAD), into numbers. The numbers can be considered to be the coordinates to be controlled by a

machine.

CAD packages are sophisticated drawing packages. They are used by engineers, architects and designers to produce detailed design plans and technical drawings. Different types of CAD modelling; 2D and 3D.

• Greater accuracy (it is possible to work to within microns)

• Objects and drawings can be created in 2D, 3D, 2D CAD and 3D CAD

• Images can be viewed from any angle

• Powerful scaling, rotation and reflection options

• Software can automatically calculate costs.

• Software itself is expensive

• Takes time to learn software, staff have to be trained

• Requires the use of a PC, which adds to costs

•Laser cutters can cut several

materials including wood, plastic, fabric, leather, paper and

rubber.

•They will also mark glass, ceramic and stone.

•Lasers can perform the following functions: cutting, deep

engraving, precision scribing

and decorative etching.

•They are extremely fast and efficient to use

KEY WORDS: Rapid prototyping, automatic, fabrication

Advantages Disadvantages

Accurate, high-quality components can be produced quickly.

A knowledge of CAD is required to prepare the drawings to use as the basis for making.

Any number of components can be produced easily time after time.

The machinery costs are high.

Modifications can be made and tested quickly. The range of equipment available and the cutting capacity.

Small, complex components can be made easily. Setting up the machine can be complex and time consuming.

Quality of finish is so high that no further finishing may be needed.
