Q

What is a prototype?

A

Prototypes are bespoke items that are designed for, or commissioned by individual clients and are classified as one-off products. Theses are one-off versions and are used to test out ideas and receive feedback from potential clients

Q

What is batch production?

A

Batch production is a method of production used when a certain number of identical products are required. This is known as a batch, as they will all have been produced together. A batch could contain a small or large amount of products e.g. Jordans

Q

What is Mass production?

A

Mass-produced products tend to be items that are in consistent use/demand and its design doesn’t change significantly. Electronic products such as the iPhone and even large assembled products such as cars are good examples. The difference between mass and continuous production is that mass-produced products are discontinued after a certain amount of time, whereas continuously produced products don’t tend to stop being produced.

Q

What is continuous production?

A

Continuous production is very similar to mass production although the products tend to be continuously produced to create mass amounts of stock everywhere around the world. For example, milk is in stock almost everywhere all around the world, at all times. This is because it is being continuously produced.

Q

How does a lathe work?

A
  • wood inside it placed on the tool rest and the taper centre would start removing mateiral by the turning of the handle
  • the speed of the lathe can be altered to increase accuracy and smoothness
  • longer wood can require additonal support
  • can rotate to allow for higher accuracy when shaping/ removing material

Q

What is a bending force?

A

Forces at an angle

32
Q

What is lamination?

A

Bonding two or more materials to improvea products strength, stability and sometimes flexability. Wood lamination is when you layer multiple pieces of wood onto eachother and bond them together to form a harder mateiral

38
Q

What is oceanic pollution?

A

When mass ammounts of waste products are dumped into the oceamn & consequently damaging/ killing ecosystems

39
Q

What is conversion?

A

Conversion is when stripped logs are taken to the sawmill & are cut into planks using equipment such as circular saws. At this point the word is known as TIMBER

40
Q

What is seasoning?

A

Seasoning is when timber is seasoned to reduce moisture. It’s seasoned either by air drying or kiln drying.

41
Q

How are timbers seasoned via air drying?

A

When timbers are air dried they are stacked so evaporation can take place easily, takes around one year to fully dry

42
Q

How are timbers seasoned via kiln drying?

A

When timbers are dried in the kiln they are dried much faster than air drying, although it cost much more to dry timbers this way

43
Q

What is felling?

A

When a tree is felled it is cut into manageable lengths. This is normally done in winter when the tree has less moisture

44
Q

What is debarking?

A

When a tree is stripped down to just the log. All bark and branches are removed and the now logs are ready to be converted into timbers

45
Q

What is rough cut timber?

A

A stock form of timber where its rough and not finished, commonly used for exterior tasks/ construction

46
Q

What is planned timber?

A

A stock form of timber that is commonly left in planks with a smooth finish & is more suitible where a quality finish is required

47
Q

How is mdf/ chipboard produced?

A
  1. The wasted branches from debarking are collected and fed into a chipper to produce small wood chips
  2. Small wood chipds are placed into resin to bind them all together
  3. Mixture is then hearted and compressed to produce a sheet of chipboard/ MDF
48
Q

Why are manufactured boards sometimes more usefull during construction than generic wood types?

A

Becase they are manmade, they can be made exactly to fit the required measurements fo a product - can generally be produced in much larger solid planks/ timbers

62
Q

Why are metals alloyed?

A
  • alloying metals can improve working properties and aesthetics
  • to produce tougher or corrosion resitstant versions of metals e.g. stainless steel
  • alloying is combining two or more metals together to give enhanced properties
63
Q

What is a negative to composite materials?

A

Upon being used its difficult to separate the combined materials which can prove difficult when recyling or attempting to biodegrade a material / do not degrade easily if littered - which foil lined board is frequrently as its used for fast food take aways
