Industrial Production All about Computer Aided Design (CAD) & Computer Aided Manufacture (CAM)
Uses of Computer Aided Design (CAD) • Paint/draw programs – e.g. annotating sketches, artwork, nets for packaging • Scanner – e.g. images from food packaging • Excel/databases – e.g. graphs for questionnaires, spreadsheets to calculate cost, star profiles • Clipart – e.g. mood boards • Digital cameras – e.g. photos of food • Word processing – e.g. creating questionnaires, tables, spider diagrams, charts • Desktop publishing – e.g. designing questionnaires/interviews • Internet – e.g. to carry out research on special diets, existing products, recipe ideas • Email – e.g. sending photos, reports • Nutrition programs – e.g. to calculate nutritional analysis of food products
Advantages of CAD • Gives greater accuracy • Gives a professional finish • Quick completion of tasks • Designs can be sent directly to manufacturing stage • Recipes can be used without waste through trials • Colours & graphics can be tried out & best ones chosen
Uses of Computer Aided Manufacture (CAM) • Sorting & grading of raw materials i.e. fruit & vegetables • Weighing out the product before packaging • Sealing the packaging • Controlling the finish of products i.e. degree of brownness of bread • Checking & maintaining temperatures • Monitoring pH levels – important to the shelf life & processing of some products • Metal detecting • Production rate • Flow rates • Moisture content
Advantages of CAM • Repetitive tasks can be carried out quickly • Production is standardised as processes are repeated with accuracy & precision aiding quality control • Productivity is increased as more products can be produced at speed to lower costs • Increased reliability of finished products as below standard products are automatically rejected aiding quality assurance • High standard of packaging can be produced consistently • Production schedules such as HACCP & stock control are dealt with easily
Effects of using CAM • Staff need to be trained to operate computerised equipment • Less staff would be needed • Visual checks by staff are still needed • Safety is increased due to equipment carrying out some or all cutting processes • Engineers are required • Computer systems may break down • If initial design is not correct or systems are incorrectly programmed a large cost could be incurred
Key Terms • Computer Aided Design (CAD) – used for designing during food production • Computer Aided Manufacture (CAM) – using computers to control machinery during food production • Quality Assurance – a system of procedures for making safe, quality products • Quality Control – systems for checking the quality during production or at the end of production • HACCP (Hazard Analysis Critical Control Point – a food safety based on the prevention of hazards
