1. CAD Computer Aided Design

2. Computer Aided Design Computer-aided design (CAD) is the use of
computer technology for the design of objects,
real or virtual.
The design elements include:
Packaging design
Bacterial modelling
Nutritional analysis

3. Computer Aided Design Packages

4. CAD - Packaging/ Product Design
Designers can produce 2D/3D images (‘virtual reality’) of new food products and packaging
The ideas can be seen by others in other parts of the office or even the world!
Changes or modifications can be made on screen

5. CAD CAD can be used for adding pictures to packaging design/artwork
Scanned images
Digital photographs
Clipart

6. CAD - Product Development
CAD packages can also be used for Product
Development .
Spider Diagram
Packaging nets
Food labels
Design ideas
Star diagrams

7. CAD - Databases
DATABASE - A collection of costs and items that can be accessed and searched through a spreadsheet.
E.g. Using spreadsheets to cost products in product development COSTING

8. CAD – Nutritional Databases
Nutritional modelling can be carried out using computer packages to create labels and nutritional data

9. CAD -Spreadsheets Spreadsheets are used to create: PRODUCT COSTINGS
SCALING UP PRODUCT RECIPES
STOCK CONTROL

10. CAD CAD can also be used for : Planning production flow charts
Research and sales forecasting
Modelling bacterial growth

11. Advantages of using CAD in the food industry
Mathematical work is done speedily and with great accuracy.
Computers allow designers to work quickly and accurately
‘Modelling’ saves money for manufacturers
Designers can model ideas without having to produce a real dish!

12. CAM: Computer Aided Manufacture

13. Computer Aided Manufacture (CAM) - Definition
The process of using specialised computers to control and monitor and adjust food processing machinery

14. CAM – Computer Aided Manufacture
Food manufacturers use computers in many of
the stages of production because they:
Do not make mistakes
Can run all day everyday without tea breaks!
Save on labour costs

15. CAM – Computer Aided Manufacture
Remove human error
Assess thousands of products in minutes
Detect things that the human eye cannot see!

16. CAM - Uses in manufacture
Cam includes:
Oven thermostats
Oven temperature and temperature adjustment
Weighing and measuring control
Rate at which ingredient is added
Amount of mixture coating being used
Timing of mixing, kneading, stirring, combining
Speed of a conveyor belt or other machinery
Metal detector
See CAD/CAM in food industry supplementing sheet for
further information

17. ICT and CAM in single item production
Microwave ovens
Timers
Bread makers
Edible icing printer

18. Computer Numerical Control (CNC)
CNC Means controlling machines using numbers and digital information
Equipment required for the system in highly sophisticated and very expensive
CAM systems use CNC machinery to carry out tasks in the production processes

19. Computer Numerical Control (CNC) – Cont...
CAM systems use CNC machinery to carry out tasks in the production processes.
Cad software can be used to drive CNC machines, e.g. Card cutters for packaging
The benefits of using CNC include the following:
-increased speed and accuracy
-increases flexibility
-continuous operations
-economical to operate

20. Example of CNC
Robot! This is a piece of equipment that is computer driven and mimics the skills of a human being Robots used for ‘pick and place’ operations e.g. Packing biscuits into a tray Stacking boxes

21. Computed Integrated Manufacture (CIM)
A system in which all the stages of in a food manufacture processes are integrated and linked and controlled by computer systems
High volume products such as bread, cereals and snack foods use CIM systems. They are essential because:
They produce high volumes quickly
They are highly accurate
Consistent result
