CAD/CAM & pre manufactured components

1. Be able to recognise the roles, advantages and disadvantages associated with CAD & CAM Determine why pre manufactured components are so useful

5. CAD (Computer Aided Design) DESIGN (Computer Aided Manufacture) MAKE Using the internet to research other food products. You have done this! Using cameras to photograph products as they come off the production line. Any products which don’t pass the camera test are rejected Using a computer to analyse the results of a questionnaire – producing graphs. You have done this! Computers are used to weigh products to ensure all products are the same size and shape. This is vital for profit and company reputation, would you buy a bag of crisps that contained different amounts? Using a the internet like survey monkey or Facebook to gain feedback on ideas. Marmite posted a ‘love it or hate it’ button on facebook, 1000’s voted, marmite had all of this information for free!!! Computers measure the temperature of fridges and freezers and these are automatically recorded, for safety purposes. Using programs like photoshop to draw food products and design packaging Computers are used to count the products which come off the production line, this tells the factory how fast they are working. Using nutrition programs to generate labels. You have done this! Computers can test the PH level of products Using costing programs to cost a product. You have done this! Computers are used to metal detect products as they come off the production line, this ensures that no physical contamination has occurred. Using emails to send important information between different departments, possibly in different parts of the world. Computers are now being used to decorate products. Like… photos on cakes at Asda.

6. ADVANTAGES OF CAD ADVANTAGES OF CAM Gives guaranteed accuracy Lots of time can be saved. Repetitive tasks can be carried out quickly. Gives a professional finish Ensures all products are identical, vital for profit and reputation, people expect certain tastes, textures and appearances when they buy their products. Allows large companies to become more connected and allows a quick line of communication The factory can produce more, this results in lower costs. Presentation of research can be presented in a meaningful way Increases safety, making sure that no physical contamination occurs. Things can be done quicker DISADVANATGES OF CAM Employees have to be trained, this can be expensive and time consuming Number of people would be reduced, particularly lower paid jobs If a computer breaks down it would cost the factory valuable time and money If a computer breaks the staff would not be able to carry out their jobs
