Unit 1 Key Ideas in Design and Technology Flashcards
Manufacturing
Creates a finished product from some raw materials. It is a system of three parts: Input, Process, Output
How can advances in technology improve manufacturing?
- Automation of manufacturing processes
- Smart technology in manufacturing
- Tracking materials, tools, equipment and products
- Communication systems
- Specialised buildings
How does automation of the manufacturing process improve manufacturing?
- Use of machines to do tasks automatically without much, or any human input
- Can be used to carry out a particular process or manufacture a whole product
- Continually being developed to be more intelligent and to allow them to work more closely with humans
Advantages of automation of manufacturing processes
- Increase speed of production -> work faster and don’t need rest -> can be cheaper than human workers
- High accuracy as they perform the same task consistently, removing human error
Disadvantages of automation of manufacturing processes
- Can replace human workers so there are fewer jobs for people to do
- Can be very expensive to buy
- Can’t carry tasks that require human judgement
How does smart technology in manufacturing improve manufacturing?
- Many computerised machines designed to carry out advanced tasks accurately (CAM/CAD etc.)
- Connect them to other machines and sensors in the factory to share data
- Use this data to help organise what tasks they need to do without human input. Also see when they’ll run out of materials and components
- Can be part of the ‘Internet of things’ -> receiving and processing online customer orders
How does tracking of materials, tools, equipment and products improve manufacturing?
- Tagging each box of material, tools, product etc.
- Can be scanned or detected as the items move around the factory to keep the status of the item up to date
- There are many uses like monitoring stock levels of raw materials and components, movement of products around the factory, and the number of finished products in stock
How do communication systems improve manufacturing?
- Smart machines can pass information around so communication requires no human input
- Humans can use devices to share information
- Devices to receive information. E.g. a tablet to direct robots around the warehouse in the most efficient route to collect items
How do specialised buildings improve manufacturing?
- Factories designed to incorporate smart technology and minimise environmental impact
- Made of modular components -> taken apart, moved or added to
- Reduced need for room -> move out of large factories to smaller, local spaces
Different ways of manufacturing to help maximise efficiency
- Flexible Manufacturing Systems (FMS)
- Lean Manufacturing
- Just in time (JIT)
How does Flexible Manufacturing Systems (FMS) help maximise efficiency?
- Different machines that carry out different tasks -> transport materials through different processes and eventually store the finished product
- Called FMS because they are easy to adapt -> fairly quick and straightforward to change the system if design is altered
- Systems are also easy to alter if the level or production changes -> extra machines etc.
How does Lean Manufacturing help maximise efficiency?
- Aims to minimise amount of resources used and waste produced
- Minimise costs and maximise efficiency
- Just-in-Time (JIT) system of stock control is a form of lean manufacturing -> delivered as they’re needed and used as soon as they’re delivered
Advantages of Just-in-Time
- Reduces the amount of space needed for the storage of materials and finished products
- Less money tied up in materials that aren’t being used
Disadvantages of Just-in-Time
- Relies on material being delivered on time and being fault-free (no time to return faulty goods).
- If those two doesn’t happen, then money can be lost
CAD
- Computer-aided design
- Designing on computer instead of pencil and paper
- Can make 2D or 3D designs
- Help model and change their designs quickly -> easy to experiment with colours and forms
- Spot problems before making anything
- Can see 3D from all angles
