ICT in business (CAM & CAD)
- CAD -
Computer
aided design.
- The use of computer systems for
design within engineering and
products.
- Examples: Producing kitchen or bathroom
designs for customers. Producing the
designs for a component that is to be
manufactured.
- Features of CAD packages
- Rendering - materials
can be displayed, you
can do many what if
type investigations to
explore the finish.
- Zoom -
Enhance parts
of drawings to
make it bigger,
to produce
more work of
more detail.
- Rotate -
Rotate in 3D
across X,Y & Z
axis, see
design from all
angles on the
outside.
- Walk-through - Visit the
building before its build, allows
spatial awareness of what he
design looks like.
- Stress/Strain - Work out weight
materials can hold, avoids
disasters later on.
- Wire drawings - See design
without any finishes, helps with
perspective.
- Advantages:
- Easily stored and
transferred, drawings are
digisted and can sent via
email.
- Can manipulate image by
the ease of manipulation of
images on the screen.
- Can produce 3D drawings which
are useful for diagrams of
kitchens.
- Can produce lists of components automatically that
can be used to create lists of dimensions and parts
needed to create the product.

- The use of computer systems for
design within engineering and
products.
- CAM - computer aided manufacturin
- The use of computer based systems to
control the machinery in manufacturing
processes e.g. Drills.
- Examples: Used to manufacture components
in car engines, used to produce a design of a
product and it taks theinput from CAD
packages & uses the info to produce a set of
instructions.
- Advantages
- Cheaper manufacturer,
the manufacture is
automatic so costs are
reduced.
- Better quality products produced by CAM
are better quality because of no human
involvement.
- Lower wage costs, very little human
involvement means the goods can be
produced cheaply as the wage costs
are lower.
- Cheaper manufacturer,
the manufacture is
automatic so costs are
reduced.
- The use of computer based systems to
control the machinery in manufacturing
processes e.g. Drills.
- Hardware/Software
requirements of
CAD/CAM
- Input - The main device used
extensively by CAD is the mouse
with 2 buttons & a keyboard.
- Processing - Speed of the graphic card -
CAD needs to perform many complex
calculations to deal with scaling, rotating or
producing 3D models from 2D designs. The
main influence is how fast the CAD system
appears to the user.
- Processing - Graphic card -
CAD places lots of demands
on graphic cards to be able
to produce visualisations in
3D from 2D designs.

on graphic cards to be able

3D from 2D designs.
- Output
- Screen - Needs to be
large to reduce eye strain
&have good resolution.
- Machinery - Output from CAD software can
then be produced using CAM machinery such
as drills & lathes, these CAM outputs are used
to automatically manufacture components.
- Screen - Needs to be
large to reduce eye strain
&have good resolution.

extensively by CAD is the mouse
