design and communication and CNC machines Flashcards
What are the 7 steps that explain the design process
design opportunity
research
brief
specification
idea generation and development
manufacture
testing and evaluation
explain design opportunity
find a problem in a product that you can solve
explain research
looking for an exising product and see how to approve
explain brief
a short description of what you are going to make
explain specification
a list of specific points that your product can do or have
explain idea generation and development
sketching out potential ideas and developing them into a final idea
explain manufacture
your making a protype
explain testing and evaluation
you test it can you approve it
what is aesthetics
how a product looks
what is ergonomics
the study of how a products interacts with the user
name 6 methods of communication
free hand sketch
presentational drawing
working drawing
mood boards
physical mock-up/models
computer-aided design (CAD)
What are 7 advantages of physical mock-up/models
a cheaper version of your design made from cardboard
physically hold and test
see what works and doesn’t work
see your manufacturing ability
cheaper than making a prototype
see things that you may not have seen on a drawing
less waist
What are 3 disadvantages of physical mock-up/models
your limited by the material
you can’t test if the material is the right one
it takes more time
what does CAD stand for
Computer Aided Design
what is CAD
it is particularly good for producing working drawings and 3D computer models.
What are 6 advantages of CAD
easier to make changes to a changes to a drawing quickly add realistic appearances.
You can change the view points.
You can send it quickly
You can go straight to CAM
You can produce an assembly drawing
You can test Your design on the screen
disadvantages of CAD
Your Start up will be expensive training is required
what does CAM stand for
Computer Aided Manufacture
what is CAM
It is a process that Converts drawings Produced by CAD into actual products
what does CNC stand for
Computer Numerical control
What are 3 advantages of CNC
Machines can work 24/7 with little human intervention
They ensure products and Consistently are produced accurately.
They are reliable They are flexible as they can be reprogrammed
disadvantages of CNC
low of skilled workers
name the 4 CNC’s machine
CNC Laser cutter
CNC Lathes
CNC Milling Machines
CNC Routers
what materials do a CNC Laser cutter cut
Plastic
wood card
what materials do a CNC Lathes cut
wood
metal
nylon
what materials do a CNC Milling Machines cut
wood
metal
acrylic/plastic
what materials do a CNC Routers cut
foam
wood
metals
application of a CNC Laser cutter
intense beam light used to cut
no clamping of material required
simple and complexed shapes can be cut
application of a CNC Lathes cut
accurate and complexed shapes produced that would be difficult to produce using hand operated lathes
application of a CNC milling machine
produced flat and complex curved shapes
application of a CNC router
similar to milling machine but using softer material can cut 2D and 3D shapes
used for block modelling
