Title: CAD-CAM in your work
1CAD-CAM in your work
- You need to show some CAD and CAM processes in
your folder-work
2- 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
3CAD 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.
4How 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
5The computer screen images show the process of a
CAD drawing that will eventually be used on a
multi headed CAM embroidery machine

11After 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
dont 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.

13Objective - 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.
