15 of 57
Light Emitting Diode
A semi conductor made up of a single junction of n- and p-type materials. As with all semi-conductors current will flow when the junction voltage has been reached but in this case light is emitted.
16 of 57
Risk assessment
A document assessing the type of hazard, the level of risk, who might be affected by the hazard, annd a description of all of the control measures taken to minimise the risk associated with using specific materials and manufacturing processes.
17 of 57
a type of semi conductor that has been doped with a more negatively charged material allowing energy to flow in the same direction as the current flow in a wire.
18 of 57
A type of semi-conductor that has been doped with a more positively charged material allowing a flow of energy in the opposite direction to the current flow in a wire.
19 of 57
Graphical User Interface
What you see on a computer screen. It is made up of the icons, toolbar, buttons and drop down menus that allow the user to make it accessible to use.
20 of 57
Intergrated Circuit
Also known as a chip - a small electronic device made out of a chip of semi-conductor material. These devices contain electronic circuits in which there may be thousands of transistors.
21 of 57
A charged atom formed when copper comes into contact with oxygen in the air.
22 of 57
Thin Film Transistor
A TFT screen is basically a liquid crystal display that has a transistor for each pixel. This allows for rapid responses on screen to inputs. Laptops and norebooks have TFT screens and they are becoming popular for desktop computers.
23 of 57
Surface Mount Components
It refers to tiny electronic components, such as resistors and capacitors, soldered to the surface of circuit boards. There are a draction of traditional through-leg components.
24 of 57
Products become obsolete as they are susperseded by better models. Some products are said to have built-in
25 of 57
Demand Pull
Consumer demand can lead to the developments in products.
26 of 57
Quick Response Manufacturing
The organisation of production to manufacture to customer demand, rather than manufacturing items to stock.
27 of 57
Electronic Point of Sale
The use of barcode readers to send sales data t distributors and manufacturers in order to maintain correct stock levels.
28 of 57
Just In Time (JIT)
The organisation of production so that customers get their orders just in time. This avoids carrying stock of materials and components, and storing finished goods.
29 of 57
Electronic Data Interchange/Exchange
The use of computer to transfer information.
30 of 57
Master Production Schedule
A scheduling system used to organise the work to be completed within a set time period.
31 of 57
Just In Time Sequence
A refinement of JIT in which parts are not only delivered at the right time and right place but are also in sequence to match the flow of a product through the assembly line.
32 of 57
A system for tracking a product from customer order through to manufacture and dispatch.
33 of 57
Materials Requirement Planning
A software system for work cells to order materials and components from their suppliers, when they require them
34 of 57
Flexible Manufacture Systems
Organising production equipment to allow manufacture of a variety of different products, as opposed to dedicated systems that can only make a single type.
35 of 57
Computer Aided Design
the use of software that can convert CAD drawings into CNC machining data
36 of 57
Computer Aided Manufacture
The use of computer numerically controlled machines to increase efficiency of production

End effector
Robot arms are terminated with an end effector. This is a gripping hand, paint sprayer, welder or other device for moving objects around.
38 of 57
Flexible Manufacturing
refers to organising production into cells of machines performing different tasks. They are typically laid out in a U shape rather than a production line.
39 of 57
Rapid Prototyping
The use of CNC machines that create 3D objects using lasers to solidify liquid polymers, known as stereo-lithography.
