Introduction of CAD

The rapid developments in the field of computers in the past four decades can be undoubted} considered as the single most significant contributing factor responsible for the boost in th technological developments. The computer has entered each and every field. It has become the most important tool in all the technological areas including design and manufacturing.

The entry  of computers in the fields of design and manufacturing has led to the emergence of new areas known as Computer-Aided Design (CAD) and Computer Aided Manufacturing (CAM).

 Computer Aided Design (CAD) : Computer Aided Design (CAD) can be defined as the use a

computer systems to assist in the creation, modification, synthesis, analysis, and/or optimization

 Computer-Aided Manufacturing (CAM) : Computer-Aided Manufacturing (CAM) can be

defined as the use of computer system to plan, manage, and control the manufacturing operations through the direct or indirect computer interface with the manufacturing machine

.

Traditionally, the design and manufacturing have been treated as two distinct and separate , activities. However, the CAD/CAM has led to the greater integration of design and manufacturing.
