notes Flashcards
benefits of automation(robots+machinery)
replace manual jobs which save labour costs
cheaper
benefit of self driving vehicles
safer for lives of elderly or impaired
what does CAD mean
computer aided design
what does CAM mean
computer aided manufacture
advantages of CAD
more accurate
cant be destroyed easily- if drawn, pen or pencil could rub off
disadvantages of CAD
more complex/difficult to use
expensive to buy equipment
security issues-risk of data being hacked
inclusive design
fits needs for everyone
focus groups
showing a small group (up to 20 people) to seek advice/feedback
what is computer numerical control (CNC) milling
machines work with numbers and dimensions
what is flexible manufacturing systems (FMS)
can be easily recalibrated, reprogrammed+ retooled
lean manufacture
manufacture whilst reducing waste
scales of production
one off
batch
mass
continuous/flow
what is one off
only one unit is made
what is batch production
a method whereby a group of identical products are produced simultaneously (rather than one at a time)
what is mass production
made in large volumes in factories with a high level of automation
what is continuous/flow production
products move along a production line continuously 24/7
example of a JIG
pastry cutters
what set up and unit costs does mass production have
high set up costs and low unit costs
example of mass produced product
furniture
example of continuous production
toilet paper, pencils
set up costs
the more automation in a production line, the higher the set up costs will be
where is a flexible manufacturing system (FMS) used
equipment factories, automobile factories, construction industries
