Manufacturing

Manufacturing

Mass Production
1. one product large quantities
2. product layout
3. special purpose machines
4. efficient
5. Three Main Principles
  1. Division of Labour
    1. specialised cooperative labour
    2. increased productivity
    3. higher quality
    4. cost effective
  2. Principle of Work Flow
    1. sequence of operations simple
    2. achieves processing intents
  3. Principle of Interchangeable Parts
    1. streamline manufacturing process
    2. machinery can be assembled on site
    3. spare parts can be provided on site
6. automation
  1. easy
  2. Transfer machines
    1. In Line Transfer Machine
      1. sequence of operations moves in straight line
    2. Rotary Transfer Machine
      1. pallets index through 90 degrees
      2. geneva mechanism
        rotating angle determined by number of slots
Batch Production
1. functional layout
2. general purpose machines( more expensive)
3. textbooks, furniture
4. a lot of waiting and reprogramming
5. automation is difficult
6. variable complex path
7. transfer machining can not be used
8. inefficient and costly due to lack of automation
9. Value Added Work
  1. utilise resources that add value to finished product
  2. work with direct effects on product
10. non value added work
  1. work customers don't pay for
  2. moving parts , reprogramming, waiting
Jobbing
1. very specific
2. low batch size >=1
3. prototypes, aeroplanes, formula 1 cars
