Production Techniques and Systems Flashcards
what is automation
use or introduction of automatic equipment in a manufacturing or other process or facility
what are the benefits of automation
replace manual jobs reducing labour costs
safer
faster
longer hours
accurate
repeatable
what are the negatives of automation
environmental impacts and space they consume might encourage people to buy hand-made goods
what are the 5 types of automation
CAD - computer aided design
FMS - flexible manufacturing system
JIT - Just in time
CIM - computer integrated manufacture
CAM - computer aided manufacture
What is CAD and how is it used
CAD is used to create 2D or 3D models or illustrations and can be used by designers engineers etc
what are the advantages of CAD
CAD is easily saved and edited
Easily copied and repeated
Worked on simultaneously
Accurate
Complex and realistic
what are the disadvantages of CAD
it can remove the freedom of sketching on paper and constrict some peoples ideas
what is CAM
where automated machinery is controlled by software to manufacture physical parts
what are examples of CAM
laser cutting, embroidery machines
what is CNC milling -
working in 3D to produce intricate + accurate machined objects such as a jet engine turbine wheel
what is CNC laser cutting
different speeds mean that laser cutters can burn or just etch the surface of a material
what are the advantages of CAM
It is fast and accurate
repeat tasks constantly
good for producing on production lines
less waste
what are the disadvantages of CAM
expensive set up
skilled engineers needed
downtime for maintenance
can be failures
what is FMS
where an assembly line of automated machines can be easily:
retooled
re calibrated
reprogrammed
when are FMS used
where products frequently change
