Scales of production One-off • Where just one product is
made for a customer. • Could be a prototype.
Batch • A set number of identical
products. • Some flexibility to
individualise designs. Mass • Products produced in
large quantities. • Often involves
automation.
Continuous • Automated production
can continue for months. • Often produces low-cost
products.

Modern production methods Uses of robots Robots can be used for:
§ remotely operated vehicles
§ manufacturing § welding § painting § quality control § packaging
CNC equipment Computer Numerical Control
§ Machines are controlled by a computer.
§ Drawings are produced using a computer (CAD) and transferred to a machine (CAM).
