D&T
Production levels.
Continuous.
creates identical products and the machines do not need to be changed. They are quite cheap.If errors happen many products are affected, wasting time and money. 
Standard components.
this makes the same product to be use in multiple products. they are normally in mass production.
Mass
This produces a high volume of identical products, using a production line. Sometimes there are different parts of the process. They are lower costs. The process also needs less skill to work as many sections are automated. This means staff need less training.
It is expensive to set up,storage of these can be
difficult.
Just-In-Time (JIT)
This is where the factory makes the same product to be used in different products. companies use it when they don't have the facilities to store the product.
Batch
these are thousands of the same product made identically. these will use more machines so people will not be needed. It is also a lot cheaper. the staff will need training for the machines. if tit is changed it all needs to stop so it does not change requally.
Lean manufacturing.
In this method of manufacture, the focus of the production side of the business promotes reducing many areas of ‘waste’ – materials, time costs – to make the business more productive. This could be tools rearranged so they are easier to reach or even to improve the location of important items and storage. The process requires time consuming data and analysis to see where improvements can be made. Putting these improvements into place can disrupt the entire manufacturing process and be very time consuming.
One-off
these are individual makings that would normally be 1 at a time. these will be more expensive and have more people working for them.
Metals.
Common ferrous metals.
mild steel
High tensile strength.
High impact strength.
Good ductility and weld ability.
A magnetic metal due to its iron content.
-
-
cast iron
Hardness – material's resistance to abrasion and indentation.
Elasticity – material's ability to return to its original dimensions after it has been deformed.

Properties.
Ductility
The ability of a material to deform by bending twisting or stretching, the ductility of a metal increases with temperature.
Malleability:
The ability of a metal to be deformed (have its shaped changed) in all direction without fracturing. This also increases with heat.
Hardness:
The ability of a material to resit deformation or indentation. Hard materials can resist drilling cutting impact and scratching.
Flow charts
-
Flowcharts use symbols to plan complicated practical and programming activities.
Different shaped boxes are used to mean different things.
