Q

Explain the reasons why CNC laser cutter may be used to cut sheet acrylic rather than a copper saw

A

Laser cutting provides better accuracy when cutting acrylic than a copper saw

Laser cutting acrylic is faster than using a copper saw

Laser cutting is done using CAD so the process can be repeated easily in mass production

Laser cutters allows larger parts to be cut than can be achieved using a copper saw

Fewer things need to be done (e.g. polishing ) to the acrylic before cutting it with a laser cutter than a copper saw

Q

How is PPC networking systems used in the production of products?

A

Master production schedule can be used to determine the quantity of products made in a time-frame

MPS can be used to determine the number of workers needed during each stage of production

MPS software will network with suppliers and stock control systems to ensure that materials are available when required

PPC make use of just in time, in order to ensure that materials and components are available when required

Q

Talk about plywood balance bike and tubular aluminium balance bike?

A

Plywood can be cut using CNC machinery - to produce shapes needed for mass production

Plywood is available in large sheets which would allows tessellation of design and manufacture without the need to join pieces together

Minimal design is requires less processes during manufacture

Plywood does not conduct heat well, so the plywood bike will feel warm to touch in any condition

Plywood can be a heavy material and this could it make it more difficult for some young children

[Tubular]
Jigs can be used to hold parts of the bike in position when being ready to be welded

Aluminium has good malleability and ductility which allows front forks to be bent in to shape without risk of fracture

Aluminium does not corrode easily - so can be used in rainy conditions

The aluminium bike will be made out of greater number of parts than plywood version

Tubular aluminium is lightweight material which will make the balance bike easier for young child to move

Q

Positive and Negatives of using biodegradable polymer instead of polypropylene?

A

[Positive]
Biodegradable break down faster than polypropylene = PP does not break down and remains in landfill

Biodegradable polymer can be made out of natural material than polypropylene (e.g. cellulose) which is non-finite = were as polypropylene is made from finite, non-renewable source

[Negatives]
Biodegradable encourage the throw away of plastic as can not be recycled = Polypropylene can be recycled and promote the recycling of materials

Biodegradable plastics produce methane gas when decompose

Bio plastics have shorter life span than PP which means that plastic can degrade before product has been used

Natural Biodegradable polymers can consume land due to starting materials needing to be grown first

Biodegradable plastics can not be recycled, so encourage throwing away of waste

Biodegradable polymers can leave toxic residue

Q

Impact of ethical sourcing for the bowl

A

Workers involved felling the tree are paid fair wage. So they can support themselves

Ethical sourcing of timber means endangered species are not felled. Helping biodiversity

Consumers are willing to pay for product, if it means that it is ethically sourced

Companies promote ethical values to aim to reduce or remove discrimination, meaning equal chance of employment

Companies employ local people, increasing employment and prevents poor communities from being exploited

Rehabilitation of the forest for long term sustainability

Q

What are the 3 reasons why Quick Response Manufacturing is used in the design ans manufacture of products?

A

Reduces lead times to allow products to be made quickly and completely

It allows low volume of products to made that require some customisation

Can be use of flexible manufacturing systems, CAD prototyping to enable efficient production

Q

Evaluate the sustainability of pewter for the tankard?

A

Pewter is malleable metal which can be rolled into thin tin sheet required for tankard without fracturing

Pewter has low melting point that allows edges of the pewter to be soldered together

Due to low melting point, pewter casts well and allows the handle of the tankered to be produced in a mould

Pewter does not tarnish so minimal polishing is required to maintain appearance of the tankard

Modern pewter is lead-free alloy which makes it completely safe to drink from

Q

3 way products can be decided and manufactured for disassembly?

A

Semi-automated disassembly using different temperature zones on disassembly lines

Product can be dissembled without the need of specialised of equipment

Instructions that allows people to understand how to dissemble a product

Q

What is open design? How does it allow for the development of products in common society?

A

Contributors are not paid and the design is donated to everyone for the good of all

Open software allows designers to gain access to resources so they can develop their own product without cost

The access of free software allows the community to be healthy and much more productive.

The use of the 3D printing with free files available to download and adapt has allowed people to make an important to their own work

Q

How can be UV be varnishing be used to finish a magazine cover?

A

UV varnish can be applied on specific areas of the cover

UV varnished paper can be recycled easily and does not require the separation of materials

UV varnish provides good abrasion resistance prevent s smudging

UV varnish paper has a smooth and good finish which also feels nice when touching

Q

Why is electroluminiscent wires suitable for the use of the shop signs?

A

The wires are waterproof which makes them suitable for outside use

The glow of electroluminiscent wire is highly visible which makes shop signs stand out

electroluminiscent wires available in many colours which allows customisation possible

electroluminiscent wires are flexible which enables them to be easily bent in to the desired shapes for the shop sign

Q

How can sub-assembly be used to manufacture of a bicycle ?

A

Using sub-assemblies can speed up the production as no need to wait for parts

Using sub-assemblies allows to suppliers to changed easily of parts. Which helps improves profit

It is not economical for a bicycle manufacturer to have facilities to manufacture each part of the bike

Sub assemblies make different parts of the bike. they are considered as parts of a product that is created as a completed part before being assembled on the final product

Q

Why is QRM is used in the design and manufacturing of products?

A

QRM is an approach to production that reduces lead times to allow products to made quickly

QRM is used to allow low volumes of products to be made that requires some customisation

QRM is use of flexible manufacturing system, to enable efficient production to take place

Q

What is hardness?

A

The ability to resist abrasive wear such as scratching

18
Q

How can feasibility studies would be used to test the practicality for production of a new car?

A

Production plans modlled by the computers to assess if the required equipment

Computer model tests the efficiency of the production line and allow improvements to be made

Computer stimulation allows manufacturers of cars to calculate all timings involved in the production of a car to allow realistic production times

Computer modelling can take factors such as staffing levels, breaks and production line maintenance….to considered when assessing feasibility

Spreadsheets can be used to calculate the cost of the operation

CAD modelling and VR headsets can be used to stimulate the interiors. Allows designer to know if the design is feasible
