parts
 great accuracy, so errors are reduced
 easy re-use of design data for other product applications.

Question 6

Cons of CAD?

Answer 6

complexity of the programs
need for extensive employee training
large amounts of amount of computer processing power
required and this is can be expensive.

Question 7

Pros of CAM?

Answer 7

precise manufacturing and reduced quality problems –
compared to production methods controlled by people
faster production and increased labour productivity
more flexible production allowing quick changeover from
one product to another
integrating with CAD, CAM allows more design variants of a product to be produced, which means that niche products can be produced as well as mainstream mass
market products. This increased customisation increases the competitiveness of businesses in both small and large market segments.
