Digital Design and Manufacture Flashcards
1
Q
What does CAD stand for?
A
Computer aided design
2
Q
What does CAD do?
A
- makes process of designing garments quicker & cheaper as physical samples not required as frequently
3
Q
What can CAD do?
A
- Experiment with colour and pattern
- Make virtual prototypes to show how the garment will look and move when worn by a human
- Present design ideas (Presentation board)
- Make patterns to be sent electronically and changed easily
4
Q
Advantages of CAD
A
- save time and money
(e.g. re-drawing garments made quicker)
(e.g. Saves paper/materials) - allow designers to be more creative with ideas
- Can electronically send copies of ideas and specs to other countries
- Errors can be detected at an early stage
5
Q
How is CAD used in industrial applications?
A
- allows the designer to rotate motifs and plan repeat patterns accurately
- creating databases of patterns and designs that can be used as a starting point (then you can change the colour/fabric easily)
- make virtual prototype that shows how the garment will move when on a human body, and look in different colour ranges (environmentally friendly)
6
Q
What does CAM stand for?
A
Computer aided manufacture
7
Q
What does CAM do?
A
- uses automated machines that are controlled by computers (often used in unison with CAD)
- used to replace a manual operation (machine can now work continuously)
- computer numerical control (CNC) can be programmed into machines and can be downloaded
(e.g. An automated circular knitting machine
8
Q
Advantages of CAM
A
Quality is more consistent
(fewer faulty goods produced)
can work with materials and chemicals that may be harmful to humans
9
Q
How is CAD used in the manufacturing process? Examples
A
Lay planning:
(e.g. computers making sure the edges of the fabrics are laid exactly on top of each other)
Computer controlled cutting:
(e.g. Many layers of fabric cut out at the same time & patterns on the fabric are in the same lace on each layer)
