AGENDA Agenda • Introduction To TPM • Why – Benefits? • Typical Maintenance Strategies • What Does TPM Look Like? • How to Start Using TPM • Sustaining • Summary / Questions TPM
INTRODUCTION TPM
Introduction What is TPM? • TPM is a method for continuously improving the effectiveness of production equipment and processes How is this Accomplished? • By improving On Demand availability of the equipment, through improved maintenance TPM
Introduction How is this Different from Other Maintenance Programs? • Primary difference between TPM and most maintenance programs is the involvement of the machine operator as a front line defense against… • Equipment breakdowns and other unplanned downtime • Scrap and rework caused by poor equipment performance • Reduced productivity due to running at reduced speeds, idling, or stoppages requiring operator attention • Equipment startup losses TPM
Introduction Brief History of TPM • Preventative maintenance originated in the United States in 1940’s • Japanese auto manufacturers studied these methods in the 1950’s • First true TPM initiative developed by Nippondenso in the late 1960’s • First true TPM in the United States developed by Kodak’s Tennessee Eastman facility in 1987 TPM
Why is TPM Important – Benefits WHY??? • Maximizes the productivity of equipment for its entire life cycle • Extends equipment life • Increases the amount of time equipment can be doing what we need it to do • Builds / Trains a workforce that can most effectively help the organization best utilize it’s equipment TPM
Why is TPM Important – Benefits WHY??? To reduce Waste? • Equipment Breakdowns • Setup and Adjustment Delays • Idling and minor stoppages • Reduced Speed • Process Defects • Reduced Yield TPM
Typical Maintenance Strategies Types • Reactive • Preventive • Predictive • Corrective Maintenance • Maintenance Elimination • All of these can have a place, yet some better than others TPM
Typical Maintenance Strategies Most Common Strategy? • “If it ain’t broke, don’t fix it”. • Reactive Maintenance TPM
Typical Maintenance Strategies Reactive Maintenance = 55% • Advantages • Low cost • Less staff • Disadvantages • Increased cost due to unplanned downtime of equipment • Increased labor cost, especially if overtime is needed ,cost involved with repair or replacement of equipment. • Possible secondary equipment or process damage from equipment failure. • Inefficient use of staff resources. TPM
Typical Maintenance Strategies Can we get better? • Time or Machine cycle based maintenance functions • Preventive Maintenance TPM
Typical Maintenance Strategies Preventive Maintenance = 31% • Developed by US Navy • Advantages • Cost effective in many capital-intensive processes • Flexibility allows for the adjustment of maintenance schedules • Increased component life cycle • Energy savings • Reduced equipment or process failure • Estimated 12% to 18% cost savings over reactive maintenance program. • Disadvantages • • Catastrophic failures still likely to occur • Labor intensive • Includes performance of unneeded maintenance • Potential for incidental damage to components in conducting unneeded maintenance. TPM
Typical Maintenance Strategies Anything Better? • Maintenance functions based on feedback, predicting that something needs to be done. • Predictive Maintenance TPM
Typical Maintenance Strategies Predictive Maintenance = 12% • Advantages • Increased component operational life/availability. • Allows for preemptive corrective actions. • Decrease in equipment or process downtime. • Decrease in costs for parts and labor. • Better product quality. • Improved worker and environmental safety. • Improved worker morale. • Energy savings. • Estimated 8% to 12% cost savings over preventive maintenance program. • Disadvantages • Increased investment in diagnostic equipment. • Increased investment in staff training. • Savings potential not readily seen by management. TPM
Typical Maintenance Strategies More? • Modifying a piece of equipment such that it will last longer. • Corrective Maintenance TPM
Typical Maintenance Strategies More? • Removing or reducing the need for maintenance to occur • Maintenance Elimination TPM
What Does TPM Look Like? TPM Implemented? • Machine Operators are trained to do much of the maintenance operations, and it’s part of their Standard Work TPM
What Does TPM Look Like? TPM Implemented? • Tools necessary are readily available TPM
What Does TPM Look Like? TPM Implemented? • Equipment modified such that easy to keep clean, easy to see when maintenance is required. Before After TPM
What Does TPM Look Like? TPM Implemented? • More examples of easily cleaned and seen Filtered Air Before After TPM
What Does TPM Look Like? TPM Implemented? • More examples of easily cleaned and seen After Before TPM
What Does TPM Look Like? TPM Implemented? • Equipment modified such that easy to maintain TPM
How To Implement? How To…. 1. Select Equipment to work on 2. Begin with 5Sing, Initial Clean Up • 3. Define Machine Operator Maintenance Tasks • Modify equipment to facilitate tasks • 4. Define Maintenance Technician Tasks • Provide “informative” tools to assist 5. Sustain TPM
How To Implement? | Equipment Selection How To…. • 1. Select Equipment to work on…. • Equipment that is giving you problems with… • Unplanned downtime • Excessive quality problems • Excessive repair costs • Premature “end of life” failures • Running slower than “design” to prevent breakdowns TPM
How To Implement? | Equipment Selection How To…. • 2. 5S Event…. • Improves ability to perform regular inspections • Allows the discovery of potential problems • Log problems and potential problems and develop an immediate action plan • Mark all lubrication, fluid connections and directions, etc • Paint equipment TPM
How To Implement? | Equipment Selection How To…. 3. Defining Machine Operator Tasks • Develop Standards and Checklists • Cleaning • Lubrication • Visual Checks • Procedures to keep equipment “as new” TPM
How To Implement? | Equipment Selection How To…. 3. Make Machine Operator maintenance tasks easier/quicker • Easy to see when things need to be maintained • Lubrication needs become obvious to operator • Routine cleaning operations easier • Machine disassembly minimized • Automate maintenance when possible • Clear signals when maintenance is needed TPM
How To Implement? | Equipment Selection How To…. 3. Defining Machine Operator Tasks (cont.) • Train Operators on…. • Visual checks • Hydraulics • Electrical / electronics • Mechanical drive systems • Complex lubrication • Safety • Procedures for minor repair and replacement • Criteria delineating operator and technician approved activities TPM
How To Implement? | Equipment Selection How To…. 3. Defining Machine Operator Tasks (cont.) • Implement Daily Operator Activities • Review checklists with operators • Ensure operator training is complete • Finalize checklist schedules TPM
How To Implement? | Equipment Selection How To…. 4. Define Maintenance Tech Tasks (Reactive) • Provide Tech support to operator questions • Provide clear communication path • Spare Parts Program • Equip Manufacturer recommendations • Breakdown History Data • Kanban TPM
How To Implement? | Equipment Selection How To…. 4. Define Maintenance Tech Tasks (Preventive) • Eliminate Equipment Deterioration • Scheduled general inspections • Equipment overhauls • Triggered by checklists • Identify and Resolve Chronic Problems • Breakdown history log • Root cause analysis methods • 5 Why analysis TPM
How To Implement? | Equipment Selection How To…. 4. Define Maintenance Tech Tasks (Predictive) • Develop and Analyze Equipment History • Plot failure history • Correlate with Equipment Quality Performance • Determine Equipment Parameters That Predict Failure • Use information from equipment manufacturer • Oil, vibration, temperature analysis • Develop Equipment Monitoring Systems • Ensure appropriate accuracy and tolerance • Lease equipment to ensure usability before purchase TPM
Sustain TPM
Sustain Sustaining…. • Measuring progress / status is key to sustaining • Primary Measurement tool is OEE • OEE – Overall Equipment Effectiveness, is measured…. OEE = Equip Availability X Performance Efficiency X Quality Rate • Audit machine operator’s standard work • Audit maint tech’s standard work TPM
Summary TPM
Summary • TPM is a method for continuously improving the effectiveness of production equipment and processes • By improving On Demand availability of the equipment, through improved maintenance • With a primary focus on involving machine operators in routine maintenance • And making that maintenance easily seen, easily done, and effective TPM
