6. • TPM is a productive maintenance implemented
by all employees in an organization.
• TPM involves everyone in the organization
from operators to senior management in
equipment improvement.
7. GOALS:
• Increase production quality.
• Increase job satisfaction.
• Using teams for continuous improvement.
• Improve the state of maintenance
• Empower employees
• Continuous process improvement
8. Why TPM ???
• Avoid wastage in quickly changing economic
environment.
• Producing goods with out reducing product quality.
• Reduce cost for production
• Produce a low batch quantity at the earliest time.
• Goods send to the customer must be non defective.
9. Principles of TPM
• Use Overall Equipment Effectiveness (OEE) as a
compass for success.
• Improve existing planned maintenance systems
• Work toward zero losses
• Providing training to upgrade operations and
maintenance skills
• Involve everyone and utilize cross-functional
teamwork
11. • Breakdown Maintenance
Repairs or replacements performed after a machine
has failed to return to its functional state
following a malfunction or shutdown.
e.g., an electric motor of a machine tool will
not start, a belt is broken, etc.
Under such conditions, production department
calls on the maintenance department to rectify
the defect.
After removing the fault, maintenance engineers
do not attend the equipment again until another
failure or breakdown occurs.
12. Preventive Maintenance
The primary goal of preventive maintenance is to
prevent the failure of equipment before it
actually occurs.
It is designed to preserve and enhance equipment
reliability by replacing worn components before
they actually fail.
It is a daily maintenance which includes
cleaning, inspection, oiling and re-tightening
of equipment.
13. Periodic Maintenance (TBM)
Time based maintenance consists of periodically
inspecting, servicing and cleaning equipment and
replacing parts to prevent sudden failure and
process problems.
Benefits –
Extended life and use of the equipment.
Reliable production at the times when machine is
needed most.
14. • Predictive Maintenance
This is a method in which the service life of
important part is expected based on inspection or
diagnosis, in order to use the parts to the limit
of their service life.
Compared to periodic maintenance, predictive
maintenance is condition based maintenance.
15. • Corrective Maintenance
Maintenance actions carried out to restore a
defective item to a specified condition
Corrective maintenance is probably the most
commonly used approach, but it is easy to see its
limitations.
When equipment fails, it often leads to downtime
in production.
In most cases this is costly business. Also, if
the equipment needs to be replaced, the cost of
replacing it alone can be important.
It is also important to consider health, safety
and environment (HSE) issues related to
malfunctioning equipment.
16. • Maintenance Prevention
It indicates the design of a new equipment.
Weakness of current machines are sufficiently
studied ( on site information leading to failure
prevention, easier maintenance and prevents of
defects, safety and ease of manufacturing ) and
are incorporated before commissioning a new
equipment.
