TPM (Total Productive Maintenance) is a proactive approach to maintenance that relies on operator involvement to optimize equipment effectiveness. It aims to eliminate equipment breakdowns and reduce defects through preventative and predictive maintenance practices. The presentation outlines TPM's role as a lean initiative, its 7 steps including operator autonomous maintenance and professional maintenance skills development. TPM begins with 5S and builds a comprehensive downtime database to predict and prevent issues through planned maintenance.
2. Slide 2
TPM as a Lean Initiative
• Competitive costs require
– Spending control
– Defect control
– Downtime reduction
• TPM = Total Productive Maintenance
– Proactive (with all employees involved)
– Preventive
– Predictive
– Planned
3. Slide 3
Why Change?
• ACTIONS:

What is TPM??
1. Starts with 5S / Visual Factory
2. Builds a comprehensive Downtime Database by
cause, frequency, and duration
3. Predicts and prevents downtime by PM system
4. Expands role of Operator as first point of early
warning and prevention
5. Develops Professional Maintenance skills
TPM is a Lean tool to optimize the effectiveness of
manufacturing equipment and tooling.

SSortort (organize)
SShinehine (clean)
SSet in orderet in order (make orderly and neat)
SStandardizetandardize (visual place for everything)
SSustainustain (maintain the system)
A safe, clean, orderly workplace is
fundamental to quality, efficiency, and teams
13. Slide 13
TPM starts with 5S
• You can’t see problems clearly when
the workplace is in disarray
• Cleaning and organizing the workplace
helps the team to uncover problems
• Making problems visible is the first step
of improvement
• Clean machines and workplace create
pride & Safety
14. Slide 14
Downtime Visual Controls
• Visual or audio alerts
– Abnormality obvious at a glance (e.g. stoppage,
reject, control fault)
– Alerting Maint and team leaders
– Provide real time “scoreboard” for employees
• Machine down light visible from aisle
• Production status board (e.g. actual counts vs. goal)
• Scrap counts and downtime minutes
• Located in clear view in shop (not in control room)
• Simple, self regulating, & employee managed

16. Slide 16
Downtime Database
• Categorize at a minimum by Equip, Tooling, C/O, Other
• Segmented bar graph for E-T-O lost time
• Subcategories for Equip (e.g.)
– Hydraulic / pneumatic
– Mechanical / lubrication
– Electrical / controls
– Shot-end components
• Subcategories for Tooling (e.g.)
– Slides
– Cores
– Inserts
– Ejector pins
• Subcategories for Other (e.g.)
– Operator error
– Materials

Predictive Maintenance Tools
• Rate/hr vs. target or historical normal output (B/W)
• Database
– MP2 / maintenance history
– statistical probability (frequency & duration)
• Physical prediction of impending failure
– Sound (bearing)
– Temperature (cooling water)
– Flash (core pins)
– Shot monitoring system
– SPC on part geometry
– Hydraulic pressure (ejector pins)
– Spindle loads (amps)
– Fluids / Lubrication analysis (milipore)
– Vibration Signature Analysis
20. Slide 20
Preventive Maintenance System
• History of downtime by major machine & tool
– Downtime measurement & tracking
– Mean Time Between Failures
– Average downtime
– Pareto of causes at component level (eg L/S or temp sensor)
– Cost to maintain
• Develop PM cards based on frequency of failure and magnitude of
average lost time (start small & grow)
– Limit & prox switches
– Shot tip / sleeve
– Critical frame and cylinder mounting bolts
– Expendable tools
– Valves, hoses, packing, seals
• PM’s have instruction, schedule/frequency & sign-off
– PM’s / repairs done in window of opportunity when machine is down
– Cycle count or date based execution of PM’s (eg cutter change)
– PM status visual (work completed / not completed)

TPM Tag System
• Problem communication tool to and from
maintenance, tool room, and production
– Identify abnormal machine conditions
• Record problem discovered by operator
• Record problem found during scheduled PM
– Status tracking system of requested repairs
– TPM visual management tool (hang tags)
– Repair history for future problem solving
• TPM Tag used for recording problem & fix
– Blue Tag-Operator or Maint responsible to repair
– Red Tag- Safety-related request (priority)
25. Slide 25
Operator/Supervisor Production Management Maintenance
1. Abnormality Identified
2. Fill out Tag Red= Safety
Blue= Prod/Maint
3. Hang C-tag as close to the defect
as possible
4. Hang A &B Tags on the TPM Tag
status board by Machine location and
area of responsibility to correct.
5.Maintenance evaluates problem. If
fixed immediately go to 6. If parts or
time needed, maint pulls A tag from
board. The A tag is MWO. The B
tag is posted on the Maint WO
status section of the TPM Board
with est. timing.
7. Operator/Supervisor check to see
if work was done.
6.After work is completed,
maintenance completes back side of
A tag and places both the A & B
tag in the work completed box
8. If OK, Operator/ supervisor
removes C tag from machine and
places ABC tags in Completed box. If
not OK, tags stay and maint is
contacted. Contact noted on tag.
9. Production management reviews
the information. Also reviews the
comments and takes actions if
required. Places tag in history file box
located in the office
Tag information is recorded and reviewed for continuous improvement of PM
database by Production and Maintenance; Repeat operator tags may indicate
Maint needs to investigate.

• Temporary Check Sheet For Clean-Up,
Lubrication, Start-up, and Shut-down:
– What items need to be done
– Who will perform the check
– How often to check
– Where the location is to be checked
– What to use for the inspection or cleaning
– Target time to complete the task

These are the 7 steps for Operator Autonomous
Maintenance:
1. Initial clean-up
2. Countermeasures for Hard-to-Access & Source
of Contamination
3. Prepare Temporary Standards
4. General Inspection
5. Autonomous Inspection
6. Standardization
7. Autonomous Management
All of these activities must work together to fully achieve a successful planned maintenance program.
Everyone must understand their roles and responsibilities and execute as a team.
Planned maintenance can no longer be the sole responsibility of the maintenance department.

This step is to enhance equipment reliability and

standards for lubrication, cleaning and items to
inspect. The experience gained in steps 1 and 2
combined with support from the maintenance group
will enable us to prepare the initial check sheets.
