INTRODUCTION :
Computer Integrated Manufacturing, known as CIM, is the phrase used to describe the complete automation of a manufacturing plant, with all processes functioning under computer control and digital information tying them together. CIM is an example of the implementation of information and communication technologies (ICTs) in manufacturing. This starts with computer aided design, followed by computer aided manufacture, followed by automated storage and distribution. One integrated computer system controls all that happens. Through the integration of computers, manufacturing can be faster and less error-prone, although the main advantage is the ability to create automated manufacturing processes. 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 the operations. It was promoted by machine tool manufacturers in the 1980 's and the Society for Manufacturing Engineers (CASA/SME).
PRINCIPLE OF CIM :
CIM relies on closed-loop control processes, based on real-time input from sensors. It is also known as flexible design and manufacturing. The output of the system is fed back through a sensor measurement to the reference value. The controller then takes the error between the reference and the output to change the inputs u to the system under control. This
