CAD (computer-aided design) is the yews of information technology to design and analyse a product or object. Designers using a CAD system instead of a traditional drafting board to create the lines and surfaces that form the object and store this model in the database. CAD software allows the designer to perform various analyses on the object, and the design is refined by adjustments based on the results. What-if questions may be asked by altering the material used in the model. Each part of the design is a separate 3D object that can be individually viewed and altered from any angle. Once the design procedure has been completed, the CAD system generates the detailed drawings required to make the product.
CAD/CAM is the yews of computers to perform many of the functions related to design and production. The computer system has to be able to process, store, and display large amounts of data representing both part and product specifications. CAD refers to the yews of information technology to design and analyse a product. CAM refers to the specialised information technology tools that automate the entire manufacturing process. A CAD system requires a high performance computer with specialised CAD software and a plotter. The software is made up of different software modules that carry out specific tasks e.g. 3D solid modelling. The CAD software stores the designs and provides data for a database, consisting of product specifications. This information is used by the CAM system.
