  • 2. Outline
    Introduction: What is TPM?
    History of TPM
    Why TPM
    TPM objectives

    Types of maintenance
    TPM Targets
    MajorLosses in ProductionLineandOrganization
    Pillars of TPM
    Pillar 1: 5S
    Pillar 2: JıshuHozen
    Pillar 3: KobetsuKaizen
    Pillar 4: PlannedMaintenance
    Pillar 5: QualityMaintenance
    Pillar 6: Training
  • 3. Total Productive Maintenance
    T: TOTAL  
    • Participation of all Employees.
    • 4. Include all Departments, operation, equipment and process.
    • Pursue the maximization of efficiency of the production system by making all loses zero.
    • 5. Zero accidents Zero defects Zero breakdowns.
    • To improve the efficiency of the equipment.
    • 6. Maintenance meansthe entire life cycle of the production system.
    • 7. Maintenance is not only to repair and maintain the machines.
  • History of TPM
    TPM is a innovative Japanese concept
    Origin of TPM can be traced back to 1951
    Nippondensoof the Toyota Groupwas the first company to introduce plant wide preventive maintenance in 1960
  • 8. Why TPM ?
    The major difference between TPM and other concepts is that the operators are also made to involve in the maintenance process.
    Avoid wastage in quickly changing environment.
    Reduce Cost of Manufacturing.
    Produce a low batch quantity at the earliest possible time.
    Goods send to Customers must be “ non – defective”
  • 9. TPM Objectives
    Increase production while, at the same time, increasing employee morale and job satisfaction.
    Hold emergency & unscheduled maintenance to a minimum.
    To provide the safe and good working environment to the worker.
    Achieve Zero Defects, Zero Breakdown and Zero accidents in all functional areas of the organization.
    Involve people in all levels of organization.
    Form different teams to reduce defects and Self Maintenance.
    To maintain the HSE conditions of plant and equipments.
    To fulfill Regulatory compliances.
  • 10. Benefits of TPM
    • Increased Employee Morale
    • 11. Increased Productivity
    • 12. ImprovedSharingandWorking as a Team
    • 13. Improved tidines and cleaning of the working place
    • 14. Improved Product Quality
    • 15. Improved Customer Satisfaction
    • 16. Reduced Costs
    • 17. Improved Delivery Time
    • 18. Enhanced safety Records
    • 19. Improved Image
    • 20. Improved Reputation
  • Types of Maintenance
    Breakdown Maintenance
    Preventive Maintenance
    a)Periodic Maintenance
    b)Predictive Maintenance
    Corrective Maintenance
    Maintenance Prevention
    I). Obtain Minimum 80% Overall Production Efficiency
    ii). Obtain Minimum 90% Overall Equipment Effectiveness
    iii). Run the Machine during lunchtime
    Operate in a manner, so that there are no customer complaint
    Reduce the manufacturing cost as much as possible
    Achieve 100% success in delivering the goods as required by the customer
    Maintain an accident free environment
    Develop multiskilled & flexible workers.
  • 22. MajorLosses in ProductionLineandOrganization
    • Failure losses – Breakdownloss
    • 23. Setup / adjustment losses
    • 24. Cutting blade loss
    • 25. Start up loss
    • 26. Minor stoppage / Idling loss.
    • 27. Speed loss - operating at low speed
    • 28. Defect / rework loss
    • 29. Scheduled downtime loss
    • 30. Management loss
    • 31. Operating motion loss
    • 32. Line organization loss
    • 33. Logistic loss
    • 34. Measurement and adjustment loss
    • 35. Energy loss
    • 36. Die, jig and tool breakage loss
    • 37. Yield loss
  • Pillars of TPM
  • 38. Pillars of TPMPillar1 : 5 S
    FIRST STEP of improvement
    SEIRI – SORTOUT:  Keep only essential items and eliminate what is not required, prioritizing things as per requirements and keeping them in approachable places. Everything else is stored or discarded.
    SEITON – ORGANIZE:There should be a place for everything and everything should be in its place.Each tool, part, supply, or piece of equipment should be kept close to where it will be used – in other words, straightening the flow path.
    SEISO – SHINE THE WORKPLACE:Keep the workplace tidy and organized. At the end of each shift, clean the work area and be sure everything is restored to its place.
    SEIKETSU – STANDARDIZATION: Work practices should be consistent and standardized. Everyone should know exactly what his or her responsibilities are for adhering to the first 3 S's.
    SHITSUKE – SELF DISCIPLINE: When an issue arises such as a suggested improvement, a new way of working, a new tool or a new output requirement, review the first 4 S's and make changes as appropriate.
    Uninterrupted operation of equipments
    Flexible operators to operate & maintain other equipments
    Eliminating the defects at source through active employee participation
    Stepwise implementation of JISHU HOZEN activities.
    Reduce process time bypredictedvalues
    Reduce oil/ lubricants consumption by predictedvalus
    Increaseuse of JH
    Preparation of employees
    Initial cleanup of machines
    Take counter measures
    Fix tentative JH standards
    General inspection
    Autonomus inspection
    Autonomus management
    KAI means changeorimprovement and ZEN means good (for thebetter). Kobetsumeansfocused. Basically KobetsuKaizen is for smalladjustmentsandcorrections but effectsthewholeprocessandcarried out on a continual basis and involves all people in the organization.
    The principal behind is that “ a very large number of small improvements are more effective in an organizational environment than a few improvements of large value.
  • 41. This pillar is aimed at ;
    • Reducing losses in the work place that affect our efficiencies.
    • 42. By using a detailed and through procedure,eliminate losses in a systematic method using various Kaizen Tools.
  • Pillar 4. PlannedMaintenance
    With planned maintenance, we evolve an effort from a reactive to a proactive method and use trained maintenance staff to help train the operators to better maintain their equipment.
    Achieve and sustains availability of machines
    Optimum maintenance cost.
    Reduce spares inventory.
    Improve reliability and maintainability of machines.
  • 43. StepsandTarget:
    Equipment evaluation and recording present status.
    Restore deterioration and improve weakness.
    Building up information management system.
    Prepare time based information system, select equipment, parts and members and map on the plan.
    Prepare predictive maintenance system by introducing equipment diagnostic techniques and
    Evaluation of planned maintenance.
    It is aimed towards customer delight through highest quality through defect free manufacturing. Focus is on eliminating non-conformances in a systematic manner.
    Quality defects are classified as “CUSTOMER END defects” and “IN HOUSE defects”.
    For customer-end data, we have to get data onCustomer-end line rejectionand field complaints. In-house data include data related to products and data related to process.
  • 45. POLICY:
    Defect free conditions and control of equipments
    QM activities to support quality assurances.
    Focus of prevention of defects at source
    Focus on precaution (Pokayoke) system.
    In-line detection and segregation of defects.
    Effective implementation of operator quality assurance.
    Achieve and sustain customer complaints at zero.
    Reduce in-process defects by 50%.
    Reduce cost of quality by 50%.
  • 46. Pillar 6: Training
    It is aimed to have multi-skilled revitalized employees whose moral is high and who has eager to come to work and perform all required functions effectively and independently. Education is given to operators to upgrade their skill.
    The employees should be trained to achieve the form phase of skill which are as under:
    PHASE 1: Do not know.
    PHASE 2: Know the theory but cannot do.
    PHASE 3: Can do but cannot teach.
    PHASE 4: Can do and also teach.
    Setting policies and priorities and checking present status of education and training.
    Establish of training system for operations and maintenance skill up gradation.
    Training the employees for up gradation the operation and maintenance skills.
    Preparation of training calendar.
    Evaluation of activities and study of future approach
  • 48. Pillar 7: Tpm Office
    Office TPM should be started after activating from other pillars of TPM (JH, KK, and QM.PM). Office TPM must be established to improve productivity, efficiency in the administrative function and identify eliminate losses. This includes analyzing process and procedure towards increased office automation.
