What Is Computer Integrated Manufacturing?

Computer Integrated Manufacturing (CIM) refers to the use of computer systems to control the entire manufacturing process. It integrates various production activities such as design, engineering, manufacturing, inventory management, quality control, and distribution into a unified digital system.

The primary objective of CIM is to automate manufacturing operations while ensuring seamless communication between different departments and machines.

Instead of operating as separate functions, all manufacturing processes work together through interconnected computer systems, creating a highly efficient and automated production environment.

Simple Definition

Computer Integrated Manufacturing is a manufacturing method where computers coordinate, monitor, and control all stages of production to improve efficiency, accuracy, and productivity.
