1. GCSE Revision Manufacturing

2. Aims of today's session
To gain an understanding of Cad Cam in industry.
What's good about it? & What's bad about?
To learn about some manufacturing processes used in industry.
What are the various ways of manufacturing packaging?

3. CAD & CAM
In industry the majority of packages are manufactured by machines.
CAD – Computer Aided Design CAM – Computer Aided Manufacturing
The benefits of a CAD and CAM are:
Designs can be checked and altered (CAD)
Designs can be ed to other countries ready for manufacturing (CAD)
Designs can be replicated and easily developed (CAD)
Accuracy is increased as there is less human intervention (CAM)
Machines are able to run 24 hours a day, 7 days a week. Meaning which decreases
human labour (CAM)
Less labour means less cost (CAM)
Machines can be set up to reduce material wastage. (CAM)
Machines can undertake tasks which could be considered unsafe for humans (CAM)
The Negatives of a CAD CAM are:
Machines need to be serviced twice a year.
Setting up can take a long time
If a tool is damaged / broken then the process would need to be restarted
They are expensive to buy and their cost can only be justified by quantity i.e. mass production
Designs may be lost due to computer failure

4. Cam1 Machine – Vinyl or Profile cutter
These are basically used for cutting out adhesive backed lettering for signs and logos. They can also be used to cut out nets on various card thicknesses to create packages or Vinyl lettering. The smaller models can only print or cut 1 design at a time. However, larger versions can be used to mass produce. The small hardened steel cutter is held firmly in a tool holder. The cutter can be removed and replaced with coloured pens to allow the machine to draw designs onto the material.
The tool holder is designed to move up and down the slide, following the design. The paper/adhesive laminate is fed into the machine automatically. As the tool holder moves, the cutting tool is pressed into the material, cutting the desired shape.

5. Die Cutting - LARGE SCALE PRODUCTION
In industry a company may need to manufacture thousands of the same net / package, every day. When large numbers have to be manufactured a DIE CUTTER is normally used as part of a production line.
The design is completed using a computer system and CAD software.
In a printers workshop, the blank pieces of card are prepared and colour is added, as well as the printing.
Back in the factory a die cutter is set up. This is made up of several hardened steel blades. The layout of the blades match the exact size as the net. A die cutter is basically a steel stamp that is used to cut and shape the net. It is designed to cut through the card on some lines whilst slightly cutting others (these are the fold lines or crease lines).
The steel die cutter is made up of specially hardened steel cutters. Each is like a blade, with a serrated edge. Sometimes the blades can be rearranged to form other shapes of net.

6. Folding Table
For an added cost to the production line, customers can request their designed packages to be delivered preassembled. Depending on the design of the package, they are either assembled by hand or partly assembled by using a folding table
The die cutter is pressed into the card by the force of the machine. The ‘stamped out’ net is then automatically placed on a folding table. Parts of the table move/fold, forming the basic package. People sometimes finish the more delicate folding operations. (This depends on the complexity of the package).
