Computer-integrated manufacturing (CIM) is the manufacturing approach to using computers to control the entire production process. This integration allows individual processes to exchange information between them and initiate actions. Although manufacturing can be faster and less prone to errors due to the integration of computers, the main advantage is the ability to create automated manufacturing processes. Normally, CIM depends on closed-loop control processes, based on the real-time input of the sensors. It is also known as flexible design and manufacturing.
Integrated manufacturing in computers is used in the automotive, aeronautical, space and naval industries. The term "computer-integrated manufacturing" is both a manufacturing method and the name of an automated computer system in which the individual engineering, production, marketing and support functions of a manufacturing company are organized. In a CIM system, functional areas such as design, analysis, planning, purchase, cost accounting, inventory control and distribution are linked through the computer with factory floor functions such as handling and material handling, direct control and monitoring of all operations.
As a manufacturing method, three components distinguish CIM from other manufacturing methodologies:
• Means of storage, retrieval, manipulation and presentation of data;
• Mechanisms to detect states and modify processes;
• Algorithms for joining the data processing component with the sensor / modification component.
CIM is an example of the implementation of information and communication technologies (ICT) in manufacturing. CIM implies that there are at least two computers exchanging information, the controller of an arm robot and a microcontroller. Some factors involved when considering an implementation of CIM are the volume of production, the experience of the company or the personnel to carry out the integration, the level of integration in the product itself and the integration of the production processes. The CIM is most useful when using a high level of ICT in the company or facility, such as CAD / CAM systems, availability of process planning and data.

Plz give a computer integrated manufacturing system notes
