INTRODUCTION TO CADCAM

How many stages in the design process?

• 6

• 7

• 8

• 5

Answer explanation

There are 7 stages in the design process:

1 - Problem identification and recognition of need

2 - Problem definition and conceptualization

3 - Geometric modelling and spatial analysis

4 - Engineering analysis and optimisation

5 - Prototype development

6 - Manufacturing process development

7 - Manufacturing implementation

What is CAD?

• The use of computer to aid in the creation, modification, analysis, or optimization of a design.

• Combining the CAD function with drafting to generate the production drawings of the part for the purpose of downstream processing.

• The use of computers for many of the planning functions such as material requirement planning, computer aided scheduling, etc.

• Generally refers to the computer software used to develop the Computer Numerical Control part programs for machining and other processing applications.

Computer Aided Manufacturing (CAM) is

(more than one correct answer)

• The use of software to automate a manufacturing process

• A detailed 2D or 3D illustration displaying the components of an engineering or architectural project
