Q

What are the risks of relying on component parts

A

Smaller component parts like memory are often produced in factories in select countries.

If you’re dependant on certain areas/companies, then you risk a shortage of items/component parts if there area problems with the manufacturers.

As a result (with supply and demand) this led to products relying in these part skyrocket.

Q

What is Glulam and what makes it good

A

Glulam is made up of specifically selected pieces of timer glued together. Like a traditional laminate, but extremely strong and durable due to the careful selection of timer, avoiding knots and other defects.

Glulam can be shaped far easier than steel. It is very strong, as it has the properties of timer, as well as the glue holding it together.

Q

What is Kevlar and what makes it good

A

Kevlar is a strand of material that is incredibly strong. It gets woven into a fabric that is then used to make stab-proof and billet-proof vests.

Kevlar is created using aromatic polyamide fibres that are extremely strong. The fibres are often woven into different fabrics and can be used with resins to create strong, solid structures (e.g Boeing 787)

Q

What is Electrohydraulic Forming and how does it work?

A

An electrical pulse generates a shock wave in the fluid (water) that forces the material (usually metal) into the shape of the former. The air is evacuated from the mould prior to forming so this does not prevent the material from forming effectively.

18
Q

Properties of Electrohydraulic Forming

A

• Single sided formed
• Can make complex shapes
• It is a fast, single stage process

19
Q

Properties of Direct Metal Sintering (DMLS)

A

• 3D metal parts
• Bespoke
• Complex Parts (often not possible with other metal manufacturing processes)

20
Q

What is Direct Metal Laser Sintering (DMLS) and how does it work?

A

Metal particles in the form of a powder are sintered using a powerful laser layer by layer to create solid and often very complex shapes. Formed from 3D CAD models.

Is great for small, complex items and one-off production.

21
Q

What is Fibre Injection Moulding and how does it work?

A

Combing some of the advantages if thermoplastic injection moulding with the strength/reinforcement properties if carbon fibre manufacturing, that provides a hybrid manufacturing technique that is both fast and cost effective

22
Q

Properties of Fibre Injection Moulding

A

• Can used existing injection moulding techniques
• Long strand moulding with additional fibre feed

23
Q

What other types of particles can injection moulding include?

A

Other particle injection moulding can include:

• Wood particles
• More sustainable - reduces plastic
• Aesthetic qualities

24
Q

What is Laser Beam Welding and how does it work

A

Although the equipment itself can be expensive, the running costs and maintenance are low. It is a very accurate method of welding and does not require a filler rod.

25
Q

Properties of Laser Beam Welding

A

• Accurate
• No filler material
• Deep welds possible
• Low running costs
• Doesn’t require a filler rod

26
Q

Why do companies Invest in New Manufacturing

A

• Long term efficiency
• Reduce labour costs
• Aesthetic qualities
• Quicker
• Waste reduction
• Progressions (makes a unique selling point (USP), gives company a market lead)
• Reduces energy costs.

27
Q

What different uses are the of ICT in Design, Manufacture, and Retail of a Product

A

• CAD/CAM
• Desktop Publishing
• Marketing (Online Ads)
• Analytics (Google Analytics)
• Research
• Online Shops
• Email
• Video Conferences
• Spreadsheets

28
Q

What is Computational Fluid Dynamics and how does it work?

A

CFD uses sophisticated computer modelling to predict the flow of gases or fluids in or around a product. Car aerodynamics is a common use, but boat design and other products where drag reduction is beneficial use CDF modelling.

(Look at how air is hitting the car and flowing over/around it)

29
Q

Properties of Computational Fluid Dynamics

A

• Simulate fluid or gas flow
• Help improve aerodynamics
• Cheaper then wind tunnel testing
• You don’t need a physical prototype

30
Q

What is Finite Element Analysis and how does it work?

A

FEA modelling allows engineers and designers to test components and whole systems against loads and other simulated stresses, such as wind or vibrations. Critical design flaws can be identified early before production is started.

31
Q

Properties of Finite Element Analysis

A

• Stress Analysis
• Test loads
• Simulate individual components
• Identify weaknesses

32
Q

What are 3 Main Types of Rapid Prototyping

A

• Stereolithography (SLA)
• Fused filament fabrication (FFF)
(3D printer technology we have in school)
(Sometimes referred to as Fused Deposition Modelling (FDM)
• Selective laser sintering (SLS)

33
Q

Benefit of Stereolithography (SLA) over 3D printing

A

A stereolithography (SLA) product is generally a far higher quality than 3D printing

34
Q

What is Selective Laser Sintering and how Nike use it?

A

Selective laser sintering tech has revolutionised the way we design cleat plates, and gives Nike the ability to create solutions that were not possible within the constraints of traditional manufacturing processes

When talking about how rapid prototyping is positive, it allows the development of products to happen quickly, as changes can be made overnight, before being tested the very next day.

35
Q

What is Electronic Point of Sale (EPOS) and how does it work

A

EPOS allows a company to electronically manage the payment of goods and manage stock levels by monitoring what products are being sold and re-ordering where necessary. (EPOS doesn’t help when stock is lost - that’s why shops do stocktake)

36
Q

Properties of Electronic Point of Sale (EPOS)

A

• Purchase total
• Stock control
• Barcodes/QR codes
• Payments

37
Q

What is Production, Planning & Control Networking and how does it work

A

Multiple systems are used in the ordering, planning and manufacturing processes, but they must all work together to allow for seamless data interchange. RFID tags, QR codes and other systems are often used to track stock and e.c.t.

38
Q

Properties of Production, Planning & Control Networking

A

• Multiple systems
• Product ordering
• Product tracking
• MPS (Master Production Schedule) (i.e what items does the shop need)

39
Q

What is Plotter Cutting and how does it work

A

A plotter cutter is a computer-controlled piece of equipment that is able to cut through vinyl, fabric, paper acrylic, and more. It is able to cut these materials into complex designs and shapes.

Once your design is ready to go in the accompanying software, it is sent off to the cutter. It is here that the motors and gears cut through the material. Because plotter cutters have motors that move along both the x-axis and y-axis, there is a wide range of flexibility and freedom when it comes to cutting designs
(Typically used for cutting vinyl)

40
Q

Advantages and Disadvantages of Plotter Cutting

A

Advantages:
• They are capable of printing on various other materials like plastic sheets, cardboard, wood, aluminum, and steel.
• Plotters can print with incredible speed and consistency.
• They can work with almost 100% accuracy
• A large number of printouts can be produced in less time.

Disadvantages:
• The plotters are large in size, therefore, need massive space for installation.
• A plotter needs heavy maintenance.
• They are not portable due to their huge size
