TPM BASICS
3
TOTAL PRODUCTIVE MAINTENANCE
  • It is a Japanese approach for
  • Creating company culture for maximum efficiency
  • Striving to prevent losses with minimum cost
  • Zero breakdowns and failures, Zero accident, and
    Zero defects etc
  • The essence of team work (small group activity)
    focused on condition and performance of
    facilities to achieve zero loss for improvement
  • Involvement of all people from top management to
    operator

4
History of TPM
TPM is a innovative Japanese concept which can be
traced back to 1951.
However the concept of preventive maintenance was
taken from USA. Nippondenso was the first company
to introduce plant wide preventive maintenance in
1960.
Nippondenso which already followed preventive
maintenance also added Autonomous maintenance
done by production operators.
5
History of TPM
Preventive maintenance along with Maintenance
prevention and Maintainability Improvement gave
birth to Productive maintenance.
By then Nippon Denso had made quality circles,
involving the employees participation. Thus all
employees took part in implementing Productive
maintenance. 
6
History of TPM
  • TPM first introduced in Japan 20 years ago and
    rigorously been applied in past 10 years
  • TPM planning implementation in Japanese
    factories supported by JIPM (Japan Institute of
    Plant Maintenance)
  • Awarded yearly prizes to various industries
  • Automotive
  • Metals
  • Chemicals
  • Rubber
  • Food
  • Glass etc.

7
  • Initially implemented in
  • high-to-medium volume production areas
  • Later successfully applied in
  • Low-volume production
  • High-to-low volume assembly
  • Development areas
  • Warehouse
  • Whole range of industry

Role of TPM
  • Answers of the following questions are able to
    tell what role TPM can play within a company
  • Does TPM replace traditional maintenance
    techniques ?
  • Why is it so important ?
  • What are its policies and objectives ?

10
TPM and Traditional Maintenance
  • Reactive maintenance inherently wasteful and
    ineffective with following disadvantages
  • No warning of failure
  • Possible safety risk
  • Unscheduled downtime of machinery
  • Production loss or delay
  • Possible secondary damage

11
  • Need for
  • Stand-by machinery
  • A stand-by maintenance team
  • A stock of spare parts
  • Costs include
  • Post production
  • Disrupted schedule
  • Repair cost
  • Stand-by machinery
  • Spare parts

12
  • Real cost of reactive maintenance is more than
    the cost of maintenance resources and spare parts
  • Pro-active maintenance (planned, preventive and
    predictive) more desirable than reactive
    maintenance

13
  • TPM enables or provides
  • The traditional maintenance practices to change
    from reactive to pro-active
  • A number of mechanisms whereby
  • Breakdowns are analyzed
  • Causes investigated
  • Actions taken to prevent further breakdowns
  • Preventive maintenance schedule to be made more
    meaningful

14
  • To free up maintenance professionals to
  • Carry out scheduled and preventive maintenance
  • Gather relevant information as important input to
    the maintenance system
  • Keep the system up to date
  • To review cost effectiveness
  • To develop and operate a very effective
    maintenance system an integral part of
    manufacturing

15
Why is TPM so popular and important ?
  • Three main reasons
  • It guarantees dramatic results (Significant
    tangible results)
  • Reduce equipment breakdowns
  • Minimize idle time and minor stops
  • Less quality defects and claims
  • Increase productivity
  • Reduce manpower and cost
  • Lower inventory
  • Reduce accidents

16
  • Visibly transform the workplace
  • (plant environment)
  • Through TPM, a filthy, rusty plant covered in oil
    and grease, leaking fluids and spilt powders
    can be reborn as a pleasant and safe working
    environment
  • Customers and other visitors are impressed by the
    change
  • Confidence on plants product increases

17
  • Raises the level of workers knowledge and skills
  • As TPM activities begin to yield above concrete
    results, it helps
  • The workers to become motivated
  • Involvement increases
  • Improvement suggestions proliferate
  • People begin to think of TPM as part of the job

18
TPM Policy and Objectives
  • Policy and objectives
  • To maximize overall equipment effectiveness (Zero
    breakdowns and failures, Zero accident, and Zero
    defects etc) through total employee involvement
  • To improve equipment reliability and
    maintainability as contributors to quality and to
    raise productivity

19
TPM Basic policy and objectives
  • To aim for maximum economy in equipment for its
    entire life
  • To cultivate equipment-related expertise and
    skills among operators
  • To create a vigorous and enthusiastic work
    environment

20
  • TPM Corporate policy for the following purposes
  • To aim for world-class maintenance, manufacturing
    performance and quality
  • To plan for corporate growth through business
    leadership

21
  • TPM Corporate policy
  • To promote greater efficiency through greater
    flexibility
  • Revitalize the workshop and make the most of
    employee talents

22

23
What is TPM?
T Total Overall efficiency. Total
production system. Participation of all
employees. P Productive Zero defect. No
trouble in operation. Safety. M Maintenance
Longer life cycle of production system.
24
What is TPM?
  • Aims at Breakthrough improvement in productivity
    and reducing chronic losses to zero.
  • Aims at Creating a bright, clean, and pleasant
    factory.
  • Means To reinforce people and facilities and
    through them, the whole organization.
  • Addresses Overall equipment effectiveness.
  • Institutionalizes Total Employees Involvement
    Participative management and an
    Overall-small group organization.
  • Eliminates inter departmental walls and
    facilitates Cross Functional Management.
  • Is material oriented it seeks to keep equipment
    in its intended condition.

25
Why TPM?
MARKET CIRCUMSTANCES
IN-HOUSE CIRCUMSTANCES
  • Rising cost of raw material
  • Higher power cost specific power
  • Higher specific fuel consumption
  • Higher man power cost
  • Heavy losses, low profit due to equipment
    failures / low reliability / indifferent attitude
  • Lower skill levels and involvement
  • Compartmentalization,
  • lack of horizontal communication
  • Low moral/ organizational politics
  • Unsafe working
  • Pressure from TOP to progress fast
  • Easy funds for /capacity build up
  • Market demand / consumption sluggish, High
    quality competition in the market
  • Result -Stiff competition, low returns
  • Opportunity to earn profit
  • Increasing quality consciousness in market
  • New plants very efficient and cost effective.
  • Increasing input material cost
  • Increasing wages and salaries.

27
Process
The process adopted is a proven methodology based
on 1.  Understanding the current
status 2.  Setting up an organisation 3.  Training
people 4.  Identifying model areas and machines
for initial improvement 5. Improvement of Model
machines to the original condition and
achievement of zero loss concept. Each machine
is to be improved by a Cross Functional Team
consisting of 1 team leader (Manager Level) and
5-6 members consisting of Engineer/Supervisor
level. 6.  Horizontal deployment of the approach
to the rest of the plant 7. Finally covers
entire organization and involve every employee
from top to bottom.

How to Calculate OEE?
42
  • Example 1
  • A medium volume manufacturing facility with a
  • capacity of producing 2 parts/minute actually
    produced 800 parts in a planned running 2 shifts
    of 8 hours each. It had breaks and scheduled
    maintenance for 40 minutes and also faced 40
    minutes breakdowns and 1 hour 20 minutes for
    changeover and adjustment. Number of rejects and
    re-works were 10 and 6 parts respectively.
    Calculate its overall effectiveness
  • Planned production time 2x8 hrs. 960 minutes
  • Loading time 960-40 (breaks scheduled
    maintenance) 920 min.
  • Down-time 40 (Breakdowns) 80(Changeover
    adjustment) 120
  • Loading time Down time 920 - 120
  • Availability --------------------------------x
    100 ----------------x100 87
  • Loading time 920

43
  • Example 1 (Contd.)
  • Quantity produced 800
  • Performance --------------------------------x1
    00 -------------x100 50
  • Time run x Capacity/given time (920-120)x2
  • Amount produced Amount defects Amount
    re-work
  • Quality ---------------------------------------
    -------------------------------- x 100
  • Amount produced
  • 800 10 6
  • -------------------- x 100 98
  • 800
  • Overall effectiveness (OEE) 0.87 x 0.5 x 0.98 x
    100 42.6

44
  • Example 2
  • A chemical plant was expected to run for 120
    hours/week continuously with production capacity
    of 2400 metric tones /hour. At the end the week
    it produced 220,000 tones together with a waste
    of 3000 tones. It had120 minutes breakdowns and
    460 minutes changeover and adjustment. Calculate
    plant overall effectiveness.
  • Planned production time 120 hrs/week 7200
    minutes
  • For continuous production, breaks and scheduled
    maintenance 0
  • Therefore, loading time 7200-0 7200 min.
  • Down-time 120 (Breakdowns) 460(Changeover
    adjustment) 580
  • Loading time Down time 7200 - 580
  • Availability --------------------------------x

MTBF
  • Mean Time Between Failure
  • The average amount of operating time between
    consecutive breakdowns for an item of equipment
    (or plant).
  • Formula
  • Operating time is productive time plus production
    delays.
  • Number of failures or breakdown events is the
    number of failures on an item of equipment (or
    plant).
  • Interpretation
  • Maintenance effort required is decreasing.
  • Maintenance practices / mechanisms are
    effective.
  • Failure frequency is decreasing.
  • Operating conditions are improving.

MTBF
  • Maintenance effort required is increasing.
  • Maintenance practices / mechanisms are
    ineffective.
  • Failure frequency is increasing.
  • Operating conditions are deteriorating.

47
MTTR
  • Mean Time To Repair
  • The average maintenance time required to keep an
    item of equipment (or plant) operational.
  • Formula
  • Down time is the total time equipment (or plant)
    is down for maintenance work (preventive and
    corrective).
  • Number of failures or breakdown events is the
    number of failures on an item of equipment (or
    plant).
  • Interpretation
  • Maintenance practices / mechanisms are
    ineffective.
  • Poor clean-up (work preparation) practices.
  • Ineffective work practices.
