Computer integrated manufacturing (CIM) is an approach that uses computers to control the entire manufacturing process. In a CIM system, functions like design, planning, cost accounting, and inventory control are linked through computers to factory floor functions like materials handling and operations management to provide direct monitoring and control of all operations. CIM allows processes to exchange information and initiate actions, enabling faster, less error-prone manufacturing and the creation of automated processes. The benefits of CIM include improved quality, shorter new product times, minimized costs and flow times, increased competitiveness, flexibility, productivity and customer service.

1. INTRODUCTION TO CIM
MODULE-I
COMPUTER INTEGRATED MANUFACTURING

2. WHAT IS CIM?
Basically Computer Integrated
Manufacturing (CIM) is
the manufacturing approach of
using computers to control the
entire production process.

3. • In a CIM system functional areas such as design, analysis,
planning, purchasing, cost accounting, inventory control, and
distribution are linked through the computer with factory floor
functions such as materials handling and management, providing
direct control and monitoring of all the operations.

6. WHAT ARE THE BENEFITS OF CIM?
• CIM allows individual processes to exchange information with each
other and initiate actions.
• Through the integration of computers, manufacturing can be faster
and less error-prone, although the main advantage is the ability to
create automated manufacturing processes.

7. BENEFITS OF CIM
CIM plays a vital role in the economy of the manufacturing system
The benefits of CIM are indicated as follows:
1. Products quality improvement.
2. Shorter time in launching new product in the market.
3. Flow time minimized.
4. Competitiveness increases.
5. Improved scheduling performance.
6. Shorter time.
7. Improved customer service.
8. Increase in flexibility and responsiveness.
9. Total cost minimized.
10. Long term profitability increases.
11. Customers lead time minimized.
12. Manufacturing productivity increases.

8. COMPUTER-AIDED TECHNIQUES:
• CAD (computer-aided design)
