What are the three types of forging ?

Casting is [blank_start]pouring[blank_end] molten [blank_start]metal[blank_end] into a die, where it then hardens. Sometimes it may need [blank_start]secondary machining[blank_end] to achieve the correct look/finish.

Label the lathe.

Are there 6 stages in LCA

[blank_start]Lean[blank_end] manufacturing is a way of reducing [blank_start]costs[blank_end]/waste produced/time. Just in time(JIT) reduces waste as parts/components are delivered just before they are needed, therfore reducing un-used parts and saving the company money. [blank_start]Kaizen[blank_end] is where floor workers suggest ways to improve efficency and can add ideas of how to keep them happy/motivated so they are working as best as possible. Poke-a-yoke is using machines to reduce time/money/waste, Robots/machines do the job quicker and more efficiently but [blank_start]cansometimes[blank_end] need humans to finsih the product; high start up [blank_start]costs[blank_end] are a downside and having someone to maintain/fix them.

What safety equipment is needed when welding?

When welding aim for a straight bead

What are the four Rs ?

Types of production !!!!

Robots are used ONLY for Exploration, packing and dispatching and Assembly

Powder metalurgy is in a [blank_start]green-state[blank_end] until sintered. Sintering joins the [blank_start]bonds[blank_end] together by melting them so more of each bond is touching. Without sintering the metal is [blank_start]brittle[blank_end] and cannot be used.

Metal foams cannot be used after one load of impact/collision

Metal foams are used in Car doors to protect passangers and reduce impact force, and also are Only used in aeroplanes because they are not flammable(resulting in no fire in a crash)

Optical fibres have 3 layers of outer coating/insulation so that no info/data is lost

Hydrogen fuel cells are a [blank_start]good[blank_end] alternative to petrol, they only produce electricity and [blank_start]water[blank_end] vapour, also they are not running out and are cheap to run. However Hydrogen is very [blank_start]dangerous[blank_end] however so that is a reason [blank_start]not to[blank_end] use them.

Nanotechnology can be used in many different industrys. Nanoparticles are measured in [blank_start]Nanometres[blank_end] (nm), a nanometre is a [blank_start]billionth[blank_end] of a normal metre. Nanoparticles can be found [blank_start]naturally[blank_end] but can also be made, or even created by accident in combustion.Nanoparticles have different particles on a nanoscale compared to a normal scale, this makes it easier to change the [blank_start]properties[blank_end] of the material.

[blank_start]Bionics[blank_end] is the science of appplying electronic principles to solve medical problems, which are normally linked to nerves, allowing for much more movement. The biggest advantage of bionics is being able to [blank_start]regain[blank_end] what has been lost(even if its sight, movement, e.t.c)

[blank_start]Blended[blank_end] wingbodies- Is where the wings are fabricated into the design of the plane meaning wings do not need to be made separately and then transported and then attached. They are used to reduce [blank_start]drag[blank_end] therefore reducing fuel used making it more fuel [blank_start]efficient[blank_end]. Also not having to attach the wings separately means the plane [blank_start]weighs[blank_end] less also making it more fuel efficient.

5 stages in pcb manufacturing, 1-design layout, 2-producing the artwork, 3-etching 4-drilling the board 5-[blank_start]populating the board with soldering[blank_end]
