Introduction to CAD/CAM
CAD or Computer Aided Design can be defined as the use of computer to assist the user in design of systems. It is a tool which is used to achieve the following functions:
- Create
- Modify
- Analyze
- Optimize
All present day CAD systems are user-friendly and are based on interactive computer graphics. As the name suggests, Interactive Computer Graphics displays data and information in the form of graphics. The designer is in the position to enter the data in the form of commands which are readily converted by the software and hardware in the graphics form. Thus, the user can create drawings, modify them and explore further possibilities and options.
In present times, where the rate at which changes are produced in design is very high, it is imperative to switch over to these tools for cost effectiveness and efficiency.

CAM or Computer Aided Manufacturing is the effective use of computer systems to plan, manage and control the operations of a manufacturing plant. Typically, the application of CAM can be divided into two broad categories:
- Manufacturing Control and
- Manufacturing Planning
The above categories represent two different levels of involvement of the computer in the operations of a plant.
