Design and Technology PG4/5
CAD
Is designing using a computer
Computer assisted design
CAM
Process of manufacturing products with help of systems
CAD software works out the coordinates of each point on the drawing
CAM machines are computer numerically controlled, they can follow the x,y,z coordinates and move the tools to cut up or build your design
Either subtraction or addition of material
Some CNC machines are CAM machines
3D printer is a CAM machine
Machines
CNC Routers
Are able to cut 2D and 3D shapes from a block of material, can also engrave things, can be used on plastic, wood and metals
Laser Cutters
They can cut plastic, wood, carboard. They are two axis so cant cut out 3D shapes. can be used for engraving
3D Printers
Rapid prototyping, print with several materials including wax and plastic
Some CAM machines are only two axis so can only cut a 2D shape
Affects of CAM and CAD on manufacturing
Saving on shipping costs
Designs for products can be sent electronically to be manufactured near where they are going to be sold, saving on shipping costs
Saving on labor costs
Some companies design in one country and manufactory in another as manufacturing is cheaper and then they ship back to wherever it is going to be sold
