Question 3

What are the advantages of using CAD?

Answer 3

• Can be more accurate than hand-drawn designs - it reduces human error
• You can save and edit ideas, which makes it easier and cheaper to modify your design as you go along
• You can modify existing ideas, which saves time

Question 4

Computer-Aided Manufacture

Question 6

Give an example of a CAM machine:

Answer 6

Laser Cutter

Question 7

What are the advantages of using CAM?

Answer 7

• In large-scale production, the results are consistent
• Enables very high accuracy levels in large-scale production
• Usually speeds up production of low-volume products

Question 8

What are the disadvantages of using CAM?

Answer 8

• The software itself is expensive so initial costs are high
• Can be slower than traditional methods for one-off or low-volume production
• Staff need to be trained how to use the software and machinery, which adds to costs
