B: The use of digital technology in designing and manufacturing proscese's pretty much done
1 CAD/M
1.1 CAD stands for computer animated design or manafacture.
1.2 CAD examples omputer, Graphics tablet, scanner (flat and 3d) internet access, 2D/3D software
1.3 CAM Examples CNC lathe miler, router, computerised embroidery, laser cutter, 3d printer plotter/cutter, vinyl cutter
2 testing, modelling and rapid prototyping
2.1 testing
2.1.1 computers can be used to test the feasability of design ideas using a range of softwares this can be used to predict the effect of loading and identify weaknesses.
2.1.2 CAA softwares can be used to analyse the effect or external factors such as vibration, or extreme temperetures. the program can predict outcomes and suggest possible improvements or modifications
2.1.3 fluid dynamic system software is used in the design of vehicles. analysing the effects of air flow. it can also be used in architecture for air conditioning.
2.1.4 computer simulations can be useful for real life situations where it is too dangerous to follow through, too much effort to complete or too expensive. however, incorrect settings could lead to great damage and expense for machines.
2.1.5 computers can be used in 2D and 3D modeelling for ideas. images can be rotated, zoomed and shown in an infinite amount of colours and textures. this can be done with ease.
2.2 prototyping
2.2.1 several systems are available that translate 3D designs into solid physical forms. this can be done in multiple ways.
2.2.2 laminated object manafacturing. this is one of the ealiest systems available buiding up layers of adheisive coated matrial. this can be time consuming resulting in the finall product having a rough texture that may need sanding down.
2.2.2.1 Stereo Lithography-a laser traces a shape of a layer onto a bath of liquid resin. this cures the resin. the platform is lowered and another layer is traced. the whole object is created. it usually has a thickness of 0.1 mm
3 Stock control, monitering and purchasing logistics.
3.1 materials and components- these are bought in from the suppliers to be used in the manufacture of products
3.2 work in progress- incomplete products currently being manafactured
3.3 finished product- assembled products of desired standards ready for distribution
3.4 production flow usually enables production to flow without costly hold ups.
3.5 electronic data interchange
3.5.1 EDI is a way in which information can be exchanged between computers within a company. used greatly in stock control.
3.6 Pros and cons
3.6.1 pros
3.6.1.1 lower costs
3.6.1.2 improve efficiency
3.6.1.3 Cater for flunctuating levels of demand
3.6.1.3.1 no manual checks needed
3.6.2 cons
3.6.2.1 initial cost set up or training
3.6.2.2 sometimes only one person can operate the system
3.6.2.3 possibility of manual input error
3.6.2.4 software or virus attack, computer breakdown can be costly
3.6.3 data can be easily stored
4 High volume production and automation
4.1 factory plants CIM ( computer integrated manufacture) is used by automated factory .
4.1.1 the planning process is used to make maximum use of resources and ensure a rapid and consistent flow with no mistakes..
4.1.1.1 CNC machines are also used for a wide range of operations including cutting, stamping, embroidering cropping welding forging, assembly making and packaging
4.1.1.1.1 . the use of systems that use visual measurement and weight sensors are used for inspection.
4.2 pros and cons
4.2.1 pros
4.2.1.1 low labor cost
4.2.1.2 low product cost through economies of scale
4.2.1.3 No production loss through disoutes
4.2.1.4 consistent quality
4.2.1.5 efficient stock control systems enables JIT
4.2.1.6 system checks and modifications easy to carry out
4.2.2 cons
4.2.2.1 Expensive initial layout
4.2.2.2 System break down is costly
4.2.2.3 protocols of all systems may not communicate
4.2.2.4 Require some flexibility in processing to enable manufacture of different products
5 product designers over the years have adapted and embraced the developing technologies and changing and changing methods of comunication and design. inthe last 40 years there has been a dramatic interesting the availability for the use of digital systems and technology
