CNC MILLING MECHINE 

CAD,by itself,means computer-aided design. Computer-aided design is a concept which encompasses any use of the computer to enhance or aid in the design process. Computers have several features that make them valuable aids to designers. These include calculation, analysis, review, modeling and testing capabilities.

Architects use CAD to develop 3D drawings of their designs—CAD can be highly specific and different versions exist for different applications—but its main function is the creation of 2D vector-based models and 3D solid and surface models. Manufacturers use CAD’s capabilities to view specific part and component designs before production, so they can check for flaws and re-design if necessary.

CAM ,by itself,means computer-aided manufacturing.Computer-aided manufacturing is a concept which encompasses any use of the computer to enhance or aid in any manufacturing process. The two best-known uses of the computer to aid in manufacturing are CNC(computer numerical control) and Robotics. Almost any type of machine used in manufacturing — lathes, mills, drills, saws, punches. shears, and so on — can be computer controlled.Industrial robots are also computer controlled.

CAM creates physical models—this is helpful when manufacturers need to check a part or component against other parts for proper fit.

Illustrated by Groover(1980),using the terms CAD and CAM together (CAD/CAM) is an attempt to show the close relationship of these concepts in a manufacturing setting. It also symbolizes a goal of the automation phase of development. That goal is the elimination of the wall between design and manufacturing that was put up by specialization during the mechanization phase.

In order to generate the actual model, CAM works alongside CAD—using CAD designs, CAM uses numerical coding to run the machine that creates the product. THOMASNET (2014) demonstrated that a CAD/CAM package allows companies to develop and save their own product designs, and program machines to create the actual component.

Today, affordable CAD and CAM software is completely main-stream among dependent industries.Software is readily available from a variety of companies and free demos and downloads are not hard to find.
