CIM & production control system, 1992.
Computer-Integrated Manufacturing (CIM) in engineering is a method of manufacturing in which the entire production process is controlled by computer. The traditionaly separated process methods are joined through a computer by CIM. This integration allows the processes to exchange information with each other and enable them to initiate actions. Through this integration, manufacturing can be faster and with fewer errors. Yet, the main advantage is the ability to create automated manufacturing processes. Typically CIM relies on closed-loop control processes, based on real-time input from sensors. It is also known as flexible design and manufacturing. verview

The term "Computer Integrated Manufacturing" is both a method of manufacturing and the name of a computer-automated system in which individual engineering, production, marketing, and support functions of a manufacturing enterprise are organized. In a CIM system functional areas such as design, analysis, planning, purchasing, cost accounting, inventory control, and distribution are linked through the computer with factory floor functions such as materials handling and management, providing direct control and monitoring of all process operations. As method of manufacturing, three components distinguish CIM from other manufacturing methodologies: * Means for data storage, retrieval, manipulation and presentation; * Mechanisms for sensing state and modifying processes;

* Algorithms for uniting the data processing component with the sensor/modification component. CIM is an example of the implementation of Information and Communication Technology (ICT) in manufacturing. CIM implies that there are at least two computers exchanging information, e.g. the controller of a arm robot and a microcontroller of a CNC...
