Materials Flashcards
What are two types of wood?
soft wood and hard wood
What are the strengths and weaknesses of soft wood?
Strengths: sustainable, light, easy to work with
Weaknesses: weak, less durable
What are the strengths and weaknesses of hard wood?
Strengths: strong, more durable
Weaknesses: not sustainable
What are two types of plastics?
Thermo plastics and thermo-setting plastics
What are the strengths and weaknesses of Thermo plastics?
They are cheap
But they are weak
What are the strengths and weaknesses of Thermo-setting plastics?
They are hard and strong
But they are rare and expensive
What is CAD?
Computer Aided Design. This is a way of digitally making 2D designs, and 3D models.
What is CAM?
Computer Aided Manufacture. This is where computers are coded to control the equipment.
What are two examples of CAD?
TechSoft 2D design and SketchUp
What are two examples of CAM?
Laser cutters and 3D printing
What are the strengths and weaknesses of CAD?
Ideas can be drawn and developed quickly, and seen with a range of materials
Some testing and consumer feedback can be done
It becomes easier to design and test a range of ideas
Computers can fail
Expensive to set up
Difficult to keep up with constantly changing and improving technology
What are the strengths and weaknesses of CAM?
Fast and accurate production
Machines can run constantly on repetitive tasks
Good for producing on a mass/flow production line
Less material wastage
Computers and machines can fail
Expensive to set up
Downtime required for maintenance
