CAD is used throughout industry and almost CAD is used throughout industry and almost everything that is manufactured started life as a everything that is manufactured started life as a drawing generated in a CAD drawing software. drawing generated in a CAD drawing software.

CAM is a software package that generates code CAM is a software package that generates code from a CAD file from a CAD file ((DelcamDelcam)). This generated code . This generated code will then instruct a CNC (Computer Numeric will then instruct a CNC (Computer Numeric Control) machine tool to manufacture objects. Control) machine tool to manufacture objects. CNC machines are used throughout industry and CNC machines are used throughout industry and can carry out quite complex repetitive work can carry out quite complex repetitive work

CAD in the textile CAD in the textile industry is used for a industry is used for a variety of tasks: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 How can you show this?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.
