Year 12 Product Design
Applications of ICT, CAD/CAM in Design andProduct Manufacture
Where ICT is used in design and manufacture it is referred to as CAD/CAM
‘ICT’ Information and communication Technology
‘CAD’ stands for Computer Aided Design
‘CAM’ stands for Computer Aided Manufacture
When computers are used in manufacture the generic term referred to is computer numerical
control
General ways in which ICT can be used
Word Processing (MS Word)
Desk Top Publishing (MS Publisher etc.)
3-Dimensional illustration (Google sketch up)
Communications (e-mail)
Web advertising
Database management
Market research
Others?
CAD/CAM products can take the form of:A simple 2-D print/photograph
A laser etching/engraving
A vinyl sign
A 3-Dimensional product produced on a three axis router or rapid prototyping machine called
a ‘3-D printer’.
Video conferencing
Others?

Computer modelling e.g. Virtual reality tours, virtual crash test simulations, screen image
rotation.
Automation and Robotics
CNC Computer Numeric Control, used to operate and drive automated systems, such as
filling and packaging lines, sorting and stock warehousing (e.g.Amazon)
Robots are also typically used in hazardous situations, such as where radiation and explosives
are present.

Flexible Manufacturing Systems (FMS)
This could be when a robot stock ‘handler’ picks items from a number of different machines
and sorts them, or transfers products from machine to machine in a set sequence.
CNC machines are not dedicated to making one product but are ‘flexible’ and versatile and
can be re-tasked. Eg. Laser cutters, lathes/milling machines, press formers,
extruders/injection moulders. Some packaging lines can handle many different products and
their cartons eg. A bottling plant.
Fused deposition modelling (FDM) is a type of 3-D printing, rather like using a glue gun to
build up layers. Our 3-D printer works in a similar manner.
Computer-integrated manufacture (CIM) Where a design team working together have
access to each other’s data, rather than design in isolation. Computers are then utilised to
schedule production events, raw materials and components ordering, stock levels, and JIT
distribution around the factory.
Just in Time (JIT) when systems are designed to ensure that customers get what they want,
at the right time and without having to stock pile materials and components.
Three dimensional scanning- now being used in the medical profession such as dentistry
when making orthodontic impressions and prosthetics. (video clip)
