CAD Computer Aided Design

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

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

CAD• CAD can be used for adding pictures to

packaging design/artwork

• Scanned images• Digital photographs• Clipart

CAD - Product Development

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

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

CAD – Nutritional Databases

• Nutritional modelling can be carried out using computer packages to create labels and nutritional data

CAD -Spreadsheets

• Spreadsheets are used to create:

• PRODUCT COSTINGS

• SCALING UP PRODUCT RECIPES

• STOCK CONTROL

CAD

• CAD can also be used for :

• Planning production flow charts • Research and sales forecasting • Modelling bacterial growth

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!

CAM: Computer Aided Manufacture

Computer Aided Manufacture (CAM) - Definition

• The process of using specialised computers to control and monitor and adjust food processing machinery

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

CAM – Computer Aided Manufacture

• Remove human error

• Assess thousands of products in minutes

• Detect things that the human eye cannot see!

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

ICT and CAM in single item production

• Microwave ovens

• Timers

• Bread makers

• Edible icing printer

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

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

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

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
