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’.

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. Advantages? ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ Disadvantages? ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ 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.
