Computer Integrated Manufacturing (CIM)
Computer Integrated Manufacturing (CIM) can be defined as the utilization of data
communications with a new managerial concept by integrating the entire manufacturing
enterprise through an advanced manufacturing approach from design to end user with the help of
computer devices. The concept of CIM was introduced in 1973 (Esmaeilian, Behdad & Wang,
2016). This paper provides a thorough discussion of CIM on the basis of extensive research and
study of the concept.
The purpose of CIM is to provide efficient organizational and personnel performance. It
is a production system that consists of many numeric control (NC) machines. These machines
are connected with a programmed materials handling system and controlled by computers (Faria
& Van, 2013). CIM is incorporated with four steps of responsibilities which are-
i. Planning which controls planning and scheduling of the procedure
ii. Control refers the management of materials and manufacturing process
iii. Material flow accomplishes the task of material handling (Faria & Van, 2013)
iv. Manufacturing process which deals with technologies, equipment, and labor.
The entire work-flow is represented in a diagram (Figure 1) which is shown in the Appendix.
CIM offers enhanced implementation in the machines’ performance with reduced man-power
and manufacturing time, providing minimized process inventory and affable scheduling.
The progression of the CIM process varies from production system to manufacturing
system. In manufacturing system (shown in Figure 2 in Appendix), there are three components-
special manufacturing system, flexible manufacturing system, and manufacturing cell. This
special system produces other components. Flexible manufacturing system processes various

parts from part number 4 to 100. The manufacturing cell constructs the minimum number of
parts with part numbers 40 to 80, despite of having maximum flexibility. On the other hand, the
production system (represented in Figure 3 in the Appendix) consists of transfer lines that
produce efficient similar parts at a large mass. Another component is stand-alone NC machine
which brings variation in the configured work parts (Computer Integrated Manufacturing
Chapter2 - CIM-introduction, 2018).
The CIM technology has the efficiency to control the entire manufacturing process by
achieving the process accomplishments from its several sub-systems like Computer-Aided
Design (CAD) which involves designing the product models, Computer Aided Manufacturing
(CAM) which controls machine tools using software programmes, Computer Aided Quality
Assurance (CAQA) which includes the software application for product quality inspection,
Computer Numerical Control (CNC) which is an equipment in CIM and it works on several
software programmes to perform complicated and critical functionalities, Enterprise Resource
Planning (ERP) which integrates finance, management, sales and services (Pedagopu & Kumar,
2014). The engineering drawings, materials listing and the overall project planning are included
under CAPP. CAPP mainly links the CAD and CAM. CAPP also optimizes manufacturing cost
and time variables, process selection, and production routes (Faria & Van, 2013). The interaction
among CAD, CAPP, and CAM is represented (Figure 4) in the Appendix.
From the above study, it can be concluded that CIM is an instance of the application of
the Information and Communication Technologies in manufacturing process through integration
of manufacturing enterprise. It plays a vital role in exchanging real-time information and
improving quality and productivity by efficiently controlling product design, manufacturing, and
marketing with the help of all its sub-systems.
