The first engineers The earliest evidence of engineering is from around 4,000 years ago. Since then, things have changed a little…




Engineering sectors Engineered products are designed and produced by companies who specialise in different sectors.

•  Aerospace •  Automotive •  Communications •  Electrical/Electronic •  Mechanical •  Biomedical •  Chemical




Engineering processes Processes can be divided into groups, which are linked by the features of the processes.

Machining Forming Fabrication Electrical/ electronic

•  Turning •  Milling •  Drilling

•  Casting •  Forging

•  Welding •  Shearing

•  PCB manufacture

•  Surface mount




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).
