Answer 1

I3d printing
Laser cutting
SLA stereo lithography

Question 2

Concurrent engineering
Definition
ads and disadvantages

Answer 2

“A method of engineering where a products development stages are run in parallel rather then series

✅speed(efficiency)✅can give to expertise (electronics China, engineers Germany)✅

Question 3

CNC

Ads dis ads

Answer 3

A computer converts a design from CAD INTO NUMBERS THESE NUMBERS THEN CONTROL THE MOVEMENT OF CUTTER,OR PRINTER.

✅24/7✅can be manufactured 100s or 100s times✅rapid prototyping ✅ don’t need model or prototype, saves time and money

❌loss of engineering skills❌more expensive than manual lathes❌❌

Question 4

Tolerance
Bought in components
Disassemble

Answer 4

Tol-when designer gives a margin of measurement I was chin the products will work
Bought in components - things you don’t need to make such as screws hinges nails ect
Like reverse engineering to find out cheaper and simpler ways to improve

Question 5

Above and below the line of a hairdryer

Answer 5

Above. -colour,shape,texture,size,user interface

Below- manufacturing process, hear settings-a motor, speed settings-a fan

Question 6

Processes for a manufacturing system in a factory

Answer 6

Production line (chicken run pie machine) a set of sequential operations established in a factory
Assembly line a manufacturing process where a semi finished assembly moves from one station to another
Cell production?

Question 7

Remote manufacturing

Ad and dis ads

Answer 7

✅cheaper✅best technology✅best components✅flexible products line✅

❌less jobs in country❌reliance on other companies❌exchange rate❌transports costs and dangers❌complex to manage

Question 8

Design approaches

Morphological analysis
Analogy
Lateral thinking
Anodise(not design approach btw)

Answer 8

M-how a product has changed over time (normally physically)
A-using one thing to design another(Velcro) (biometrics)
L-Open thinking
Anodise- to add colour

Question 9

History
What’s makes an icon
Icon examples

Answer 9

Lasts through time, recognised internationally, other manufacturers try to imitate

Icons- red phone box

• zipper
• coke bottle

Question 10

Cell production
Definition
Ads and dis ads

Answer 10

Iceland production has flow production line split into number of self contained units each team or “cell” is responsible for a significant part of the finished article

✅better quality managements than mass✅skilled engineers in their forte

❌could struggle to keep up with demand❌can’t do mass❌have to pay labour expenses

Question 11

Importance of design specification

Answer 11

Tells the designer what a product has to do and it’s requirements.

Question 12

Augmentation
Galvanising
Machine able

Answer 12

A-to make larger
G-permanently adding zinc, to an alloy or object
M-capable of being cut or shaped with machinable tools.
