Answer 3

Improved accuracy and precision; easy to modify designs; faster design process.

Question 4

List two disadvantages of using CAD.

Answer 4

High initial cost for software and hardware; requires trained operators.

Question 5

List three advantages of using CAM.

Answer 5

Consistent high quality; increased production speed; reduced human error.

Question 6

List two disadvantages of using CAM.

Answer 6

Expensive to implement; reliance on software and machinery which can fail.

Question 7

Briefly describe the CAD process.

Answer 7

Designers create detailed 2D or 3D digital models using specialised software.

Question 8

Briefly describe the CAM process.

Answer 8

The digital design is converted into instructions for manufacturing machines to produce the product automatically.
