TPM Guide: Total Productive Maintenance

TPM changes maintenance from "the maintenance department fixes breakdowns" to "everyone keeps the equipment healthy". This guide explains the pillars and how they look on a real shop floor.

What it means

Total Productive Maintenance (TPM) is an approach where operators share responsibility for equipment condition with the maintenance team. Operators do daily cleaning, inspection, lubrication and basic checks; maintenance handles planned, predictive and specialised work.

Why it matters in manufacturing

Breakdowns are one of the biggest losses in OEE, and most breakdowns give warning signs — noise, vibration, leaks, loose parts — that an operator sees first. TPM catches problems early, extends equipment life and frees skilled maintenance people for improvement work.

How TPM is implemented

  1. 1

    Start with initial cleaning

    Deep-clean the equipment to bare condition. Cleaning is inspection — leaks, cracks and loose bolts become visible.

  2. 2

    Fix sources of contamination

    Stop leaks and chips at the source so the machine stays clean, instead of cleaning forever.

  3. 3

    Create autonomous maintenance standards

    Define daily checks the operator can do safely: oil levels, abnormal sounds, gauge readings, bolt tightness.

  4. 4

    Train and certify operators

    Operators learn the checks, the limits and when to call maintenance. Skills are verified, not assumed.

  5. 5

    Build planned maintenance

    Maintenance schedules time-based and condition-based tasks using breakdown and inspection data.

  6. 6

    Track losses and improve

    Use OEE and breakdown records to attack the biggest equipment losses one by one.

Practical shop-floor example

Illustrative learning example — not a client result

Example: CNC spindle failure prevented

During daily cleaning an operator notices coolant discoloration and a faint new noise from the spindle area, and reports it through the autonomous maintenance sheet. Maintenance finds a failing bearing and replaces it in a planned two-hour stop — instead of a two-day breakdown in the middle of a customer order.

Common mistakes

  • Treating TPM as a cleaning campaign only.
  • Giving operators checklists without training or time to do them.
  • Maintenance ignoring operator-reported abnormalities.
  • No measurement — breakdowns and OEE never reviewed.
  • Starting on every machine at once instead of a model line.

Practical checklist

  • Model machine or line selected
  • Initial cleaning completed and abnormalities tagged
  • Daily operator checks defined with limits
  • Operators trained and checks audited
  • Planned maintenance schedule in place
  • Breakdown and OEE data reviewed monthly

Frequently asked questions

What are the main pillars of TPM?

Commonly: autonomous maintenance, planned maintenance, focused improvement, quality maintenance, early equipment management, education and training, safety and environment, and TPM in administration.

How is TPM connected to OEE?

OEE measures the losses — breakdowns, minor stops, speed loss, defects. TPM is the system that reduces those losses, so OEE is the natural scoreboard for TPM.
