Engineering Revision

1. Machining Processes

   • One Off Jobs
   • Bathc Production
   • Mass Production
   • Continuous production

2. Forming Processes

   • Casting
   • Forging
   • Moulding

3. Robots

   • Uses
     • Car Building
     • Bomb Desposal
     • Household Jobs
     • Hoover control
     • Rescue missions
     • Army
     • Personal Assistant
     • Manual labour
     • Survailence
     • Medical Surgery
     • Dental Care
     • Construction
     • Transportation
   • Advantages and Disadvantages
     • Advantages
       • Can work for longperiods on battery and for ever on AC electric
       • Is relaible
       • Cheaper than maual labour
       • Faster work
       • Precise

4. CNC Machinary

   • What is CNC used for in Engineering
     • Pnumatic wepon ejection systems
     • Automotive: Car prototypes
     • Automotive: car door handle
     • Aerospace: Engine turbine plate
     • Chemical: Pipe transportation valves
     • Biomedical: Protective guards (Plastic)
     • Automotive: Car wheel bearing manufacture
     • Electronic: Wire Line
     • Making of cirict boards and ciricuits
   • Advantages and Disadvantages
     • Advantages
       • CNC machines can be used continually 24/7 and only need to be switched off for occasional maintainance.
       • CNC machines are programmed with a design which can be continually used for ever making products which are identical
       • Less skilled or trained people can operate CNCs unlike manual lathes or milling machines which need skilled engineers.
       • CNC machines are cheaper when up and running than employing a machinist
     • Disadvatages
       • CNC machines are more expensive to purchase than maually operated machines
       • The CNC machine operator only gets basic training which can eman some faults being caused with the product because of the inexperience
       • Many contries no longer teach tradition techniques becuase of electronic techinques meaning there is a lack or machanical engineers.
       • Electricity and running coss are high

5. Materials

   • Cars
     • Sport
       • Light Matirial such as Carbon Fibre
     • More Standard
       • Steel or Aluminium
   • Mild Steel
     • Quite Cheap compared to some matirials but also heavy
   • Bikes
     • Titanium, Aluminium, Carbon Fibre, Mild Steel

6. Fibre Optics

   • Data Transfer
     • Broadband
     • Quicker than Dial Up

7. Hydrogen Fuel Cells

   • Good for use in cars
   • Alternitive to standard Petrol or other fuels
   • only release water

8. Telematics

   • communication
   • revolutionary communication

9. Bionics

   • New Limbs
     • For people in the army who may have lost limbs in a battle or fight
     • Or for people who may have had accidents or been born without limbs

10. Sustainability

    • Recyclable matirials
    • Renuable sources
    • Don't break Down
    • A broom is more sustainable than a hoover

11. Four R's

    • Reduce
      • Definition
        • Minimise the amount if matirial and energy you use
      • How to Help
        • Chang production techniques to make less waste
    • Reuse
      • To recycle items and use them again fro the same or a different perpose
    • Recycle
      • This is when you sue the matirials to make osmething else
    • Recover
      • Finding ways to save or reuse energy in a manufacturing process
    • All about Sustainability
      • What is more sustainability, A broom or a hoover?
        • The broom because it needs less maintainance because it has less moving parts na wood is a renuable matirial.
