2. Definition of CIM
manufacturing enterprise through the use of
integrated systems and data communications
coupled with new managerial philosophies that
improve organizational and personnel efficiency.”
• Computer-integrated manufacturing (CIM) is
the manufacturing approach of using computers
to control the entire production process.
“CIM is the integration of the total

3. What is CIM?
CIM is the integration of all enterprise operations and activities
around a common corporate data repository.
It is the use of integrated systems and data communications
coupled with new managerial philosophies.
CIM is not a product that can be purchased and installed.
It is a way of thinking and solving problems.
This integration allows individual processes to exchange
information with each other and initiate actions.

4. Application of CIM

5. Potential Benefits of CIM
Improved customer service
Improved quality
Shorter time to market with new products
Shorter flow time
Shorter vendor lead time
Reduced inventory levels
Improved schedule performance
Greater flexibility and responsiveness
Improved competitiveness
Lower total cost
Shorter customer lead time
Increase in manufacturing productivity
Decrease in work-in process inventory

6. Role of Computer in Manufacturing
The computer has had a substantial impact on
almost all activities of a factory.
The operation of a CIM system gives the user
substantial benefits:
Reduction of design costs by 15-30%;
Reduction of the in-shop time of a part by 30-60%;
Increase of productivity by 40-70%;
Better product quality, reduction of scrap 20-50%.

7. Role of Computer in Manufacturing

8. Manufacturing Method
As a method of manufacturing, three components
distinguish CIM from other manufacturing
methodologies:
Means for data storage, retrieval, manipulation and
presentation
Mechanisms for sensing state and modifying processes;
Algorithms for uniting the data processing component
with the sensor/modification component.
CIM is an example of the implementation of
Information and Communication Technologies(ICTs)
in manufacturing.

9. CIM & Production
Control System

10. Key challenges
There are three major challenges for the development of a smoothly
operating computer-integrated manufacturingsystem:
Integration of components from different suppliers: When
different machines, such as CNC, conveyors and robots, are using
different communications protocols. In the case of AGVs (automated
guided vehicles), even differing lengths of time for charging the
batteries may cause problems.
Data integrity: The higher the degree of automation, the more
critical is the integrity of the data used to control the machines. While
the CIM system saves on labor of operating the machines, it requires
extra human labor in ensuring that there are proper safeguards for the
data signals that are used to control the machines.
Process control: Computers may be used to assist the human
operators of the manufacturing facility, but there must always be a
competent engineer on hand to handle circumstances which could not
be foreseen by the designers of the control software.

11. Subsystems in computer- Integrated manufacturing
CAD (Computer-Aided Design) involves the use of
computers to create design drawings and product models.
CAE (Computer-Aided Engineering) is the broad
usage of computer software to aid in engineering tasks .
CAM (Computer-Aided Manufacturing) is the use of
computer software to control machine tools and related
machinery in the manufacturing of work pieces.
CAPP (Computer-Aided Process Planning) is the use
of computer technology to aid in the process planning of a
part or product, in manufacturing.

12. Quality Assurance)CAQ (Computer-Aided
engineering application
is the
of computers and computer
controlled machines for the inspection of the quality of
products.
PPC (Production Planning and Control) A production (or
concerned with planning and controlling all aspects
manufacturing) planning and control (MPC) system is
of
manufacturing, including materials, scheduling machines and
people, and coordinating suppliers and customers.
ERP (Enterprise Resource Planning) systems integrate
internal and external management information across an
entire organization, embracing finance/accounting,
manufacturing, and sales and services.

17. Advantages Disadvantages
 Responsiveness to shorter
product life cycles
 Better process control
emphasizes product quality
and uniformity.
 Supports and co-ordinates
exchange of information
 Designs components for
machines.
 Decreases the cost of
production and maintenance
 Unfamiliar technologies
used.
 Requires major change in
corporate culture.
 Reduction in short term
profit.
 Perceived risk is high.
 High maintenance cost and
expensive implementation.

26. CIM PRODUCT CYCLE
• Step by step evolution of product cycle
• CAD include in geometric modeling,
simulation system, finite element system.
• Computer Aided Planning and Control
(CAMPC) induce to store database and
production and process planning by
scheduling.
• CAM including in CNC machines,fms etc by
