10 Surface Debelopments Or Nets

Question 1

Surface developments

Answer 1

A 2d version of an item that will eventually be assembled into an3D object

Question 2

Die cutting

Answer 2

An industrial process used to produce large quantities of the same surface development. Used for irregular shapes and is an expensive option. I is used when numbers are needed of the irregular shapes

Question 3

Tesselation

Answer 3

The arrangement of a surface development that reduces waste to an absolute minimum

Question 4

What does fast food packaging like a McDonald’s happy meal box have at the bottom?

Answer 4

A crash bottom. This is due to them being able to be delivered flat (so more can be at a time) and then from there it can easily be constructed

Question 5

Manipulation

Answer 5

Reducing or enlarging a design. Can be done to shrink or enlarge an image whilst keeping its dimensions relative

Question 6

Mirroring

Answer 6

Selecting an axis on which to produce a mirror of a line shape a design of a picture. Can save time in the long run

Question 7

What is CAD?

Answer 7

Computer-aided design. Is about using computers to assist you during the design process. You can:

• Produce on a variety of different materials
• Rotate the design through 360 degrees on an axis
• Design can be manipulated + mirrored easily ( with a click of the mouse)
• Any area of a design can be viewed at a range of magnifications

Question 8

What is CAM?

Answer 8

Computer-aided manufacture. It’s about the manufacturing process related to a computer system. Many advantages. E.g) ensures each product produced is exactly the same as the prev

Question 9

How can CAD and CAM be linked?

Answer 9

By converting the numerical data of a design into machine data that can be used to drive h machine. These sera if data are known as G and M codes usually. Most systems will offer a simulation of the cutter path, so that you can ensure it is as expected
