Automated machinery that is controlled by software to manufacture physical parts
CAM uses Computer Numerical Control (CNC) and CAD files to generate 3D tool paths for the machinery to follow
CAM machines include laser cutters, embroidery machines, CNC milling machines, routers and lathes
CAM software:
- Very accurate/eliminates human error
- Repetitive accuracy
- Save and reload drawings to suit demand
- High speed/can run 24/7
- Reduced labour costs
- Increased health and safety due to machines covering dangerous human jobs
|
- High set up costs
- Training people to use/fix CNC machines can be difficult
- Workers being replaced by machines leads to low worker moral
- High skilled engineers need to be employed to fix comples machines - expensives
- Can't detect faults easily

CNC machines:
There are many different types of CNC machines:
- Laser Cutting: Uses a high-powered laser to cut or engrave materials with precision.
- Routing: A CNC router moves a spinning cutting tool to carve and shape materials like wood, plastic, and metal.
- Milling: A rotating cutting tool removes material to create complex shapes and features.
- Turning: Involves rotating the workpiece while a cutting tool removes material, commonly used for cylindrical parts.
- Plotter Cutting: Uses a blade or laser to cut materials like paper, vinyl, and fabric for signage and packaging.
- Can run 24/7
- Designs can be manufactured many times
- Less skilled employees needed
- CNC machine can be improved through software updates
- Reduced labour costs
- Repeatable accuracy
|
- High set up costs
- Increased unemployment
- Old skills lost
