Q

Give 3 disadvantages of an enterprise resource planning system

A
  • Extremely expensive to install and costs are incurred during ‘switching over’ period
  • Retraining is required for all department to effectively implement change
  • Resistance to change is a common reason for failure of such a system

Q

Give the 5 stages of lean manufacturing

A
  1. Value (Focus on value of what customer is prepared to pay)
  2. Value stream (Identify how value adding activities affect efficiency)
  3. Flow (Design processes result in uninterrupted material flow from raw material to finished product)
  4. Pull (Design manufacturing for ‘pull’ of product as a response to demand)
  5. Perfection (Adopt an approach that continually improved working processes)

Q

What is Kaizen?

A
  • Perfection system
  • Small changes are made to the production process resulting in small improvements being made, which tend be low cost and small (e.g. Toyota factory)
17
Q

What is a manufacturing cell?

A

Group of workstations, machines or equipment arranged such that a product can be processed from work station to another without having to wait for a batch to be completed

18
Q

Name the 3 types of manufacturing cells

A
  • Functional cells (Perform a specific function)
  • Group technology cells (Perform a series of operations for several production lines)
  • Product focused cells (Product focused and typically manufacture one type of product through series of operations)
19
Q

Give 5 advantages of computer-aided manufacture

A
  • Greater control of the production process a s fully automated
  • Safer working environment due to less risk to humans
  • Flexible production as CNC machinery can be quickly reprogrammed
  • Scale of production can be linked directly to customer demand
  • Improved productivity as production rates are consistent, less waste and reduced costs
20
Q

Give 3 disadvantages of computer-aided manufacture

A
  • Extremely high set up costs, due to expensive machinery
  • Negative effect on employment as CAM requires less human involvement
  • Worker morale may be affected due to ‘machine minding’
21
Q

How can computer-aided quality control be achieved within a manufacturing cell?

A

Using a coordinate measuring machine (CMM) for extremely accurate dimensional measurement

22
Q

What is a coordinate measuring machine?

A

Mechanical system designed to move a measuring probe to determine the coordinates of pointe on the surface of a workpiece to measure the sizes and positions of features or mechanical parts

23
Q

What is an automated storage and retrieval system?

A

Automated robotic system for sorting, storing and retrieving items in a warehouse

24
Q

What is an automated guided vehicle?

A

Materials-handling device that is used to move parts between machines or work-centres

25
Q

Name 4 types of automated guided vehicles and their applications

A
  • Towing vehicles (First type introduced, pull a variety of trailers)
  • Pallet trucks (Designed to transport palletised loads to and from floor level)
  • Fork trucks (Ability to device loads both at floor level and on stands)
  • Assembly line vehicles (Application involving serial assembly processes)
26
Q

Give 2 of the top 10 manufacturing myths

A
  • Myth 01 (Manufacturing jobs are all monotonous, strenuous and low paid)
  • Myth 08 (Manufacturing is not a creative industry)
