ICT applications in PD and manufacture

Question 1

What is CAD and when is it used?

Answer 1

CAD stands for Computer - Aided Design. It is used to speed up the designing process.

Question 2

What is Rapid Prototyping (RPT)?

Answer 2

The use of CNC machines that creates 3D objects using lasers to solidify liquid polymers, known as stereolithography.

Question 3

What is Layered object modelling (LOM)?

Answer 3

A type of rapid prototyping machine that cuts layers of self-adhesive card or paper, which are the assembled into a 3D model.

Question 4

What is Fused deposition modelling (FDM)?

Answer 4

A type of rapid prototyping machine that extrudes layers of liquid polymer to build up a model.

Question 5

What is Virtual reality (VR)?

Answer 5

The use of 3D simulation software that enables designers to produce photo-realistic images of products in lifelike settings and to interact with them.

Question 6

How does virtual reality help designers?

Answer 6

It allows designers the opportunity to see and manipulate their designs in a photo-realistic, 3D environment.

Question 7

Give an example of VR being used in a company?

Answer 7

At Jaguar, designers and production engineers use VR systems to plan how production cells will work.
It makes tremendous cost savings for the company and helps to reduce the lead-time of new models.

Question 8

What is Computer-Integrated manufacture (CIM)?

Answer 8

The use of computers to link together businesses and manufacturing data and the control of production, in order to make production more efficient.

Question 9

What is Computer-aided engineering (CAE)?

Answer 9

The use of computers to model engineering problems and simulate working conditions to see how they perform.

Question 10

What is CAM?

Answer 10

Computer- Aided Manufacture

Question 11

What are the benefits of CAM?

Answer 11

• Reduces production time.
• High accuracy in large scale production.
• Consistent results.
