What is CAD system in manufacturing?

CAD/CAM refers to the integration of Computer-aided design (CAD) and Computer-aided manufacturing (CAM).
CAD/CAM software is used to design and manufacture prototypes, finished products, and production runs of products using a single development tool..

Where did computer-aided manufacturing come from?

Computer-aided manufacturing was also developed in the 1950s, when computers were used to create G-code which was in turn translated into punched cards that could control machines.
Punch tapes were produced through computer control, which could then increase the speed of both instruction creation and manufacturing..

Why is CAD important in computer?

Purpose of CAD
It helps users create designs both .

1. D and
2. D designs to better visualize construction.
CAD enables the development, modification, and optimization of the design process.
Engineers can make more accurate representations and modify them easily to improve design quality.

Why is CAM important?

The benefits of CAM
Greater speed in producing components.
Greater accuracy and consistency, with each component or finished product exactly the same.
Greater efficiency as computer controlled machines do not need to take breaks.
High sophistication in terms of following complex patterns like tracks on circuit boards..
