Computer-aided manufacturing (CAM) is a process whereby instructions are directly communicated to manufacturing machinery by computers. CAM is used primarily in the control of robotics, fabrication, and assembly. Applications of CAM range from small-scale production to the use of robotic machines on large-scale assembly lines. CAM generally is implemented with the use of specialized equipment and software, and with computers more powerful than the typical personal computer.

In CAM, a computer is used to control the manufacture of objects such as parts made of plastic, metal, or wood. Operations to be controlled by computer may include drilling, milling, lathing, and polishing. The CAM process for manufacturing a new object begins with an operator loading the design specifications into the CAM system. The CAM software will usually then select the best cutting tools for the material to be used and set the most effective cutting...
