CAD systems require a 8 computer with fast processor and large memory 8 graphics tablet 8 plotter 8 CAD software package. Advantages of CAD 1. Alterations to plans don t require re-drawing. 2. 3D virtual reality models of CAD plans can be computer generated so allowing designers to view plans. 3. The software automatically checks the design meets any rules eg all parts must fit together without gaps. 2D CAD Package Design Accurate drawings are less difficult lines can be shortened lengthened i iideleted or rotated at the click of a mouse button. so changes to designs can be tried i iiout very quickly to see the effect designs can be rotated and viewed from different angles. Highly Skilled Technical Drawer Accurate drawings take a great deal of skill a long time to create plans many drawings have to be created to iii see the object from different angles time to get perfect each change requires redrawing. 3D CAD Package Design 3D CAD designs give nonspecialists a better idea of the final design. S-Grade Computing Automated Systems Manufacturing 1 CAM Computer Aided Manufacture CAM is the use of computers to control the production process. Equipment in CAM systems is controlled using CNC Computer Numerical Control . Equipment controlled CNC will be perfect to a fraction of a millimetre unlike humans. CAM Process CAD Design is created into a control program. Advantages of CAM 1. Production is faster than older methods. 2. Consistent quality of output. 3. Waste can be minimised. 4. Fewer workers are required so associated costs are reduced. S-Grade Computing Automated Systems Manufacturing 2 Computers in Manufacturing Worksheet Take your time to read over the notes. Answer the .
