Total Productive Maintenance TPM Overview Dave Hoyte, CEO JL French Corporation

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

Why Change? �ACTIONS: ◦ Reduce defectives / scrap ◦ Reduction of lost production time ◦ Lowest possible cost by reducing waste

Lean System Peak Performance Pull system / flow production Rapid Changeover / Customer-driven lot size Continuous Waste Reduction Lean Measures 5 S Visual Factory TPM Standardized Work Variation reduction / Six Sigma In-Station Process Control Leadership by Example & Commitment Employee Involvement & Mutual Respect

7 Wastes �Transportation �Excess production �Added processes �Motion �Waiting � Inventory �Non-conformance (defectives)

Causes of Waste � Excess Manning ◦ Poor layout and material presentation ◦ Rework and extra processes ◦ Inconsistent / inefficient work methods � Excess Downtime ◦ Tooling condition ◦ Unreliable equipment ◦ Long changeovers ◦ Incapable process � Defectives - Rework or Replace ◦ Incapable processes or process not compatible with customer expectations or design spec (design for mfg) ◦ Tooling condition ◦ Operator methods and errors

What is TPM? ? TPM is a Lean tool to optimize the effectiveness of manufacturing equipment and tooling. 1. Starts with 5 S / 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 Planned, Predictive, & Preventive 1. Starts with 5 S / Visual Factory 2. Builds a comprehensive downtime data base 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. Professional Maintenance

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

TPM starts with 5 S �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

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

TPM is Planned, Predictive, & Preventive 1. Starts with 5 S / Visual Factory 2. Builds a comprehensive downtime data base 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. Professional Maintenance

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 ◦ Slides ◦ Cores ◦ Inserts ◦ Ejector pins for Tooling (e. g. ) � Subcategories ◦ Operator error ◦ Materials for Other (e. g. )

Predicts and prevents downtime by PM system 4. Expands role of Operator as first point of early warning and prevention 5. Professional Maintenance

Predictive Maintenance Tools � Rate/hr vs. target or historical normal output (B/W) � Database ◦ MP 2 / 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

� 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 is Planned, Predictive, & Preventive 1. Starts with 5 S / Visual Factory 2. Builds a comprehensive downtime data base 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 � One point lessons for operator awareness � Creates OMP (Operator - Maintenance Partnership) � Operator performs checks, problem solving, and improvements 5. Professional Maintenance

TPM Production Operators • Clean & Check • Observe • Categorize Production Planning & Control • Schedule P. M. Active Planned Maintenance Process Manufacturing Engineers • Equipment Planning • Equipment Studies Quality Engineers • Standards & Calibrations

OMP �Operator Maintenance Partnership training in TPM �Operator basic equip inspection & tooling checks �Operator basic cleaning �Operator lubrication check �One point lessons (capture knowledge) �TPM Board & TPM Tags (proactive operator involvement)

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)

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 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.

STEP 3: Prepare Temporary Standards This step is to enhance the equipment reliability & maintainability. �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
