|| **The advantages of using CAM:** || || **The disadvantages of using CAM:
 * **The advantages of using CAD:**
 * 1) Easy to modify and edit designs.
 * 2) Virtual prototypes can be produced, (these can be visual and functional).
 * 3) Prototypes can be tested virtually.
 * 4) Designs can be communicated worldwide
 * 5) Allows for easy collaboration between designers, clients and manufacturers.
 * 1) Consistent quality of production
 * 2) Machines can run 24 hours a day.
 * 3) Machines require minimum human input and down time minimised.
 * 4) Rapid prototypes can be manufactured and tested very quickly.
 * **The disadvantages of using CAD:**
 * 1) Cost of some very advanced software.
 * 2) Cost of hardware powerful enough to run software.
 * 3) Constant training requirements as software is constantly updated.
 * 1) Cost of machines.
 * 2) Cost of running the machines.
 * 3) Human input required is minimal.
 * 4) Cost of training (Software and Hardware).

T here are some **CAD/CAM** processes that you **must know** about. These are listed below with some **videos** showing the **actual processes**.

 * 1) Laser cutting.
 * 2) Rapid prototyping.
 * 3) Virtual testing.
 * 4) CNC milling.
 * 5) CNC turning.
