Computer Integrated Manufacturing (CIM) refers to an integrated computerized manufacturing system that combines all the elements of Computer-Assisted Design (CAD) and Computer-Aided Manufacturing (CAM). CIM is an interactive computer system usually installed on a Local Area Network (LAN) that links several related departmental functions such as design, engineering, production, and marketing.
Key Features and Components of CIM
Integration of CAD and CAM
CIM integrates the engineering design and manufacturing processes using CAD for design and CAM for production. This integration ensures that design data is consistent and accurate throughout the product development cycle.
Real-time Data Coordination
The system enhances rapid, high-quality product development and manufacturing by coordinating all related functions in real time. This includes scheduling, inventory management, quality control, and machine control.
Interactive and Networked Systems
CIM systems are often networked, ensuring that various departments such as design, engineering, production, and marketing can share data seamlessly. This is typically achieved through a Local Area Network (LAN).
Applicability of CIM
In Manufacturing Industries
CIM is widely used in manufacturing industries where precision and efficiency are crucial. For example, automotive manufacturing, aerospace, electronics, and consumer goods industries all benefit from the coordinated environment provided by CIM.
In Product Lifecycle Management
CIM supports the entire product lifecycle from initial design through to production and delivery, making it a cornerstone in the realm of Product Lifecycle Management (PLM).
Quality Assurance and Flexibility
Integrating quality control processes within CIM allows for real-time monitoring and adjustments, thereby ensuring high-quality standards are maintained. This flexibility allows manufacturers to swiftly adapt to design changes and market demands.
Historical Context
The concept of CIM emerged in the 1980s as a response to the complexities of modern manufacturing processes. Early implementations focused on automating individual tasks, but as technology advanced, the focus shifted towards a more holistic approach, integrating all aspects of manufacturing.
