Benefits of TPM1.Increase productivity and OPE
OPE-Overall Plant Efficiency
2.Rectify customer complaints.
3.Reduce the manufacturing cost by 30%.
4.Satisfy the customers needs by 100%.
5.Reduce accidents.
6.Follow pollution control measures.
7.Higher confidence level among the employees.
8.Keep the work place clean ,neat & attractive.
9.Achieve goals by working as team.
10.Horizontaldeployment of a new concept in all areas of theorganization.
11.Share knowledge and experience.
12.The workers get a feeling of owning the machine.

OEE-Overall Equipment
EfficiencyO.E.E. = Availability X Performance rate X Qualityproducts rate
Availability = ( Loading hoursDowntime ) / Loading hours
Performance rate = Net utilization rate X Speed utilization rate
Net utilization rate = ( Output X Actual cycle time ) / ( Loading
hours-Downtime )
Speed utilization rate = Standard cycle time / Actual cycle time
Quality products rate = ( No. of quality products ) / Input volume
No. of quality products = Input volume( Startup defect volume +
No. of process defects + No. rework defects )

Types of Maintenance[ A ] Breakdown Maintenance
It means that people waits until equipment fails & repair it.[ B ] Preventive Maintenance
(a) Periodic Maintenance:
Time based maintenance and replacing parts to prevent suddenfailure and process problems.
(b) Predictive Maintenance:
It is conditions based maintenance.
(c) Corrective maintenance
Equipment with design weakness must be redesigned to improve
reliability or improving maintainability.(d) Maintenance Prevention
It indicates the design of a new equipment and are incorporatedbefore commissioning a new equipment.

PILLAR2 ( KAIZEN )Kai Change
Zen Good for betterKaizen Policy :
1. Concept of zero losses in every place
2. To achieve cost reduction targets in all resources
3. To improve overall plant equipment effectiveness
4. Extensive uses of PM analysis as a tool for eliminating losses
5. Focus of easy handling of operators
Kaizen Target :
Achieve & sustain zero losses with respect to minor stops,measurement and unavoidable downtimes.
Tool used in Kaizen :
1. PM analysis2. Why - Why analysis
3. Kaizen summary
4. Summary of losses
5. Kaizen register
8/11/2019 Training JH Pillar

PILLAR2 ( KAIZEN )
Purpose: Realize zero losses of all types, such as failure
losses and defect loses
Demonstrate ultimate production efficiency
improvement.Activates:
1. Understanding the 16 major losses
2. Calculating and setting goals for overall
equipment efficiency, productivity andproduction sustained
3. Implementation of PM analysis

New methods of cleaning and lubricating are
used
Including good quality machine parts. This avoid
defects due to poor JH . Inspection that is made in preventive
maintenance is included in JH .
The frequency of cleanup and inspection is
reduced based on experience.
