CAD Computer Aided Design

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 labelsand 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
