Solution:

computer-aided manufacturing:

• Computer-aided manufacturing implies manufacturing itself, aided or controlled by computers.

• In a wider sense, it denotes all the activities in the manufacturing environment like the use of computers in inventory control, project management, material requirement planning, data acquisition, testing, and quality control.

• Improved reliability gave the better manufacturing methods and controls at the manufacturing stage, the products thus manufactured as well as of the manufacturing system would be highly reliable.

• Since most of the components of a CAM system would include integrated diagnostics and monitoring facilities, they would require less maintenance compared to conventional manufacturing methods.

• Because of the Computer Numerical Control (CNC) machines used in production and the part programs being made by the stored geometry from the design stage, the scrap the level would be reduced to the minimum possible and almost no rework would be necessary.

• Since all the information and controlling functions are attempted with the help of the computer, better management control of the manufacturing activity is possible.

• All the above advantages when properly translated would mean a lower total cost and consequently, a higher final earnings.

• Therefore any manufacturing activity in a production unit (job shop production or mass-scale manufacture) can get the benefits of Computer Aided Manufacturing.

• However, better results can be obtained when the design and manufacturing activities are properly integrated.

• Also, when there is a large variety of products or minor changes required in the existing production program, CAM can easily manage the necessary changes or alterations. The following are the main advantages of using CAM.
