One benefit of CAD/CAM for global companies is:
increased manual labour
reduced product quality
improved collaboration across different locations (worldwide)
higher production costs
One disadvantage of CAD/CAM is:
increased manual labour
Computers can be affected by viruses, and file corruption
improved collaboration across different locations (worldwide)
lower set up costs
Which of these is not an advantage of CAD/CAM?
You can view the product from all angles
Computers can be affected by viruses, and file corruption
Improved collaboration across different locations (worldwide)
Once your idea is drawn out, you can model and change designs quickly, experimenting with different colours and varying the shape and dimensions
Which of these is an advantage of CAD/CAM?
Workers need to be trained in how to use CAD/CAM
Computers can be affected by viruses, and file corruption
high set up costs
Once your idea is drawn out, you can model and change designs quickly, experimenting with different colours and varying the shape and dimensions
CAD/CAM can save shipping costs
Designs for products can be sent electronically, to be manufactured near where they will be sold, which saves on the costs of shipping large amounts of finished products.
True
False
CAD/CAM can save labour costs.
Designs for products can be sent electronically from one country, to be manufactured in a country where labour is cheaper, which can reduce their costs - even if they have to pay to ship the products back to sell them in their own country!.
True
False
CAD software and CAM machines use X and Y co-ordinates for 2D shapes
and X, Y and Z for 3D shapes. The point where the co-ordinates all meet - (0,0 for 2D) or (0,0,0 for 3D) - is called the ______.
datum
data
zero point
starting point
