CAD-CAM in your
work
You need to show some CAD and
CAM processes in your folder-work

CAD, CAD/CAM and CNC involve precision
manufacture from design stage through to production.
CAD Computer Aided Design involves generating
drawings from software.
CAD is used throughout industry and almost
everything that is manufactured started life as a drawing
generated in a CAD drawing software.
CAM is a software package that generates code from a
CAD file (Delcam). This generated code will then
instruct a CNC (Computer Numeric Control) machine
tool to manufacture objects. CNC machines are used
throughout industry and can carry out quite complex
repetitive work
CAD in the textile industry is used
for a variety of tasks:

Why is CAD software used in the textile industry?
Helps designers draw accurately.
You can see the products in 3D.
You can rotate the design and view it from all angles.
To make changes and modifications quickly and easily.
To experiment with different patterns, textures and
colourways.
To develop basic or standardised designs.
To improve the quality of the design.
To use simulations to test the design.
How can you show this?
These pictures show a range of
fabric patterns and body forms with
the colour range of the product.
This is completed using a CAD
programme
The computer screen
images show the
process of a CAD
drawing that will
eventually be used on a
multi headed CAM
embroidery machine
After trialling out several types of CAD
programmes in the ICT suite and the
textiles room I now have an idea about
how good CAD and CAM can be. I
have decided not o use CAD in my
project as many of the designs did not
link into my work.
The Janome 300E machine has a good
range of existing programmed designs,
which can link into many projects. But
the sizes are limited and don’t allow you
to scale them up or down to a great
extent. Therefore, I will not use this
embroidery system as part of my work.

Objective - To know why CAD and
CAM are used in the Textile Industry

Success Criteria
My goal is to understand why CAD and CAM
are used in the textile industry
To actually complete a sample to show that I
have developed skills in using a CAM
embroidery machine
I need to think about the cost implications when
manufacturers use such processes.
