This document provides an introduction to CAD/CAM/CIM. It defines CAD as using computers to assist in the design process. CAM is defined as using computers to plan, manage and control manufacturing operations. CIM attempts complete automation of all manufacturing processes under computer control by integrating CAD, CAM, and other business aspects. The document discusses various design and manufacturing disciplines. It explains the need for CAD/CAM/CIM is to increase productivity, improve quality and communication, create databases, optimize tool paths, and help with production scheduling. The scope of CAD/CAM/CIM allows for more effective design, manufacturing, and factory integration.
