NIST Manufacturing Systems Integration Program

Computer-integrated manufacturing (CIM) is a method of manufacturing in which the entire production process is controlled by computer. The traditional manufacturing environment is transformed into a highly automated and integrated system, where all aspects of production are linked through computer systems. This integration allows for more efficient production processes, improved product quality, and reduced lead times.

Overview

CIM involves the use of computer-aided design (CAD), computer-aided manufacturing (CAM), and other computer-based technologies to control and manage the entire manufacturing process. The goal of CIM is to create a seamless and automated production environment where all components of the manufacturing process are interconnected and can communicate with each other.

Components of CIM

CIM systems typically include the following components:

• Computer-aided design (CAD): The use of computer systems to create, modify, analyze, and optimize a design.
• Computer-aided manufacturing (CAM): The use of software and computer-controlled machinery to automate the manufacturing process.
• Computer-aided engineering (CAE): The use of computer software to simulate performance and improve product designs.
• Enterprise resource planning (ERP): Integrated management of core business processes, often in real-time, mediated by software and technology.
• Manufacturing execution system (MES): A control system for managing and monitoring work-in-process on a factory floor.
• Robotics: The use of robots in manufacturing to perform tasks that are repetitive, dangerous, or require precision.

Benefits of CIM

The implementation of CIM offers several benefits, including:

• Increased production efficiency and flexibility.
• Improved product quality and consistency.
• Reduced production costs and lead times.
• Enhanced ability to respond to market changes and customer demands.
• Better data management and decision-making capabilities.

Challenges of CIM

Despite its advantages, CIM also presents several challenges:

• High initial investment costs for technology and training.
• Complexity in integrating various systems and technologies.
• Need for continuous maintenance and updates.
• Potential job displacement due to automation.

Applications of CIM

CIM is used in various industries, including:

• Automotive industry
• Aerospace industry
• Electronics industry
• Consumer goods industry
• Pharmaceutical industry
