What is CAD & CAM?

  

CAD (computer aided design):

Computer aided design is the integration of the computer and graphics to aid in the areas of design and drafting. Computer aided design and drafting software are design for mechanical designer and draftsmen, but also for the other fields.

Architectural firms use form of CAD. Use of CAD architecture can draw different design like room plan and different structural model.

Computer aided design, or simply CAD, by definition is the combination of hardware and software components providing the tool of planning and designing and modeling.

History of CAD:

The history of CAD began traced back to 1950. CAD was initially used on mainframe computers in early 1980 Auto Desk revolutionized CAD system by making Auto-CAD, which could be run on a PC.

 
Uses/Application of CAD:

The CAD is used in great number of professional application. This can be a category.

1. MCAD (mechanical CAD). Used by engineers to design complex parts of different machines.
2. AEC (architectureengineering and construction) used for creation of buildings and their system.
3. GIS (geographicalinformation system) to generate maps from topographic data. Automobile designer at large auto manufacturing plants use cad to design many prototypes of different cars before creating solid models.

CAM (computer aided manufacturing):

CAM a type of automation in which computers communicate all working instructions direct to manufacturing machinery. Today a single only one computer can control banks of robotics milling machine, lathes, and welding machine and other tools. The use of computer to control the factory machines in the manufacturing process is called computer aided manufacturing (CAM).

CNC (computer numerical control):

CNC is the system in which operator program computer that control the milling process apparatus. A human does not attend the actual machine. Unlike a human, a computer-controlled difficult tasks. CNC devices make a possible to cut more difficult parts with greater precision. Often a CNC machine a connected to a CAD workstation. By watching the monitor, the CNC operator can view the part as the machine is making it.
