Computer Integrated Manufacturing

Introduction

Computer Integrated Manufacturing (CIM) is a manufacturing approach that utilizes computer technology and software to integrate various manufacturing processes and systems. It involves the use of computers, automation, and information technology to streamline and optimize manufacturing operations. CIM enables the seamless flow of information and materials throughout the entire manufacturing process, from design and planning to production and delivery.

CIM plays a crucial role in modern manufacturing as it allows for increased efficiency, improved quality, reduced lead times, and enhanced flexibility. By integrating different components and systems, CIM enables manufacturers to achieve higher levels of productivity and competitiveness.

Evolution of CIM

The concept of CIM has evolved over time, driven by advancements in technology and the need for more efficient manufacturing processes. The evolution of CIM can be traced back to the early 1970s when computer technology started to be used in manufacturing.

Key milestones in the development of CIM include:

1. Introduction of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) systems
2. Development of Computer Numerical Control (CNC) machines
3. Integration of CAD/CAM systems with CNC machines
4. Implementation of Enterprise Resource Planning (ERP) systems

These advancements in technology have paved the way for the integration of various manufacturing processes and systems, leading to the emergence of CIM.

CIM and Systems View of Manufacturing

CIM is based on the systems view of manufacturing, which considers the entire manufacturing process as a system composed of interconnected components. The goal of CIM is to achieve seamless integration and coordination among these components.

The CIM wheel concept illustrates the various components that are integrated in CIM. These components include:

1. Design and Engineering
2. Planning and Scheduling
3. Production
4. Quality Control
5. Inventory Management
6. Supply Chain Management

By integrating these components, CIM enables manufacturers to optimize their operations and achieve higher levels of efficiency and productivity.

CIM IT & Concurrent Engineering

Information Technology (IT) plays a crucial role in CIM. It involves the use of computer systems, software, and networks to facilitate the flow of information and enable real-time monitoring and control of manufacturing processes.

Computer systems and software are used in CIM for various purposes, including:

1. Design and simulation
2. Process planning
3. Production control
4. Quality control
5. Inventory management
6. Supply chain management

Concurrent engineering is another important aspect of CIM. It involves the simultaneous design and development of products and manufacturing processes. By involving all relevant stakeholders from the early stages of product development, concurrent engineering ensures that the manufacturing process is optimized for efficiency and quality.

Economic Impact of CIM

CIM has a significant economic impact on the manufacturing industry. By implementing CIM, manufacturers can achieve cost savings, efficiency improvements, and increased productivity.

Some of the economic benefits of CIM include:

1. Reduction in production costs through automation and optimization
2. Improved product quality and reduced defects
3. Reduced lead times and faster time-to-market
4. Increased production capacity
5. Enhanced flexibility and responsiveness to customer demands

CIM also has implications for the workforce. While it may lead to job displacement in some areas, it also creates new job opportunities in areas such as IT, automation, and maintenance.

Real-world Applications and Examples

Numerous companies across various industries have implemented CIM to improve their manufacturing processes. Some notable examples include:

1. Toyota: The automotive giant has implemented CIM to optimize its production processes and achieve higher levels of efficiency and quality.
