Define the Internet of Things
- The network of multiple micro electronic devices operating using wifi and the internet
- For example Kanban, a JIT manufacturing system that can order new stock when needed
Name 4 modern materials and their uses
- Kevlar: Bulletproof vests
- Glulam: Building structures
- Graphene: Medical treatment, batteries
- Precious metal clay (PMC): Jewellery
Name 5 new methods of manufacture
- Electrohydraulic Forming
- 3D printing of metals using direct laser syntering
- Fibre injection moulding
- Laser beam welding
- Physical vapour deposition
Outline the Method, Advantages, and Applications of: Electrohydraulic Forming
- Sheet metal is forced against a former by a shockwave from in electrical spark in a water tank
- Fast, high detail
- Electrical appliances, car parts
Outline the Method, Advantages, and Applications of: 3D printing of metals using direct metal laser sintering
- A laser fuses metal particles layer by layer
- Complex, strong, and lightweight parts can be made
- One of prototypes and test parts
Outline the Method, Advantages, and Applications of: Fibre injection moulding
- Injection moulding using pellets of glass or carbon fibre filled polymers
- Sustainable as it provides a use for carbon fibre waste
- Sports equipment
Outline the Method, Advantages, and Applications of: Laser beam welding
- Intense heat from a laser is used to join metals
- Fast method of welding, no finishing needed
- Shipbuilding
Outline the Method, Advantages, and Applications of: Physical vapour deposition (finishing Process)
- Base material is vapourised and deposits a thin layer
- Durable, abrasion resistant
- Food packaging, machine tool tips
