TPM is a Lean initiative that aims to optimize equipment effectiveness through proactive, preventative, and predictive maintenance involving all employees. It starts with 5S and visual controls to make problems visible. A comprehensive downtime database tracks causes to predict and prevent issues through planned preventative maintenance. Operators expand their role in early problem detection through autonomous maintenance checks and problem solving. The goal is reducing waste like defects and downtime through continuous improvement.

9. What is TPM??
TPM is a Lean tool to optimize the effectiveness of
manufacturing equipment and tooling.
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

12. 5S Workplace
A safe, clean, orderly workplace is
fundamental to quality, efficiency, and teams
Sort (organize)
Shine (clean)
Set in order (make orderly and neat)
Standardize (visual place for everything)
Sustain (maintain the system)
Slide 12

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
Slide 13

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. 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

19. 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
Slide 19

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)

Slide 23

24. 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)
Slide 24

25. Tag Process
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 5.Maintenance evaluates problem. If
status board by Machine location and fixed immediately go to 6. If parts or
area of responsibility to correct. 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 6.After work is completed,
if work was done. maintenance completes back side of
A tag and places both the A & B
tag in the work completed box
8. If OK, Operator/ supervisor 9. Production management reviews
removes C tag from machine and the information. Also reviews the
places ABC tags in Completed box. If comments and takes actions if
not OK, tags stay and maint is required. Places tag in history file box
contacted. Contact noted on tag. 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.

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
