TPM is a new technique of equipment maintenance that strives to achieve perfect production: No Breakdowns No Small Stops or Slow Running No Defects No Accidents
In this the machine operators are also involved in the maintenance processes unlike in the others.
Autonomous maintenance. Planned maintenance. Quality maintenance. Focused improvement. Early equipment management. Training and Education. Safety, Health and Environment. TPM in Administration.

PREPARATORY STAGE 1. Announcement by Management in the organization. 2. Initial education 3. Setting up departmental committees. 4. Establishing work system and target. 5. Master plan for institutionalizing. INTRODUCTION STAGE IMPLEMENTATION STAGE INSTITUTIONALISING STAGE
Identifies the percentage of planned production time that is truly productive. Developed to support TPM initiatives by accurately tracking progress towards achieving “perfect production”. OEE = A*PE*Q A= (MTBF-MTTR)/MTBF PE = RE*SE
Where A=availability of the machine PE= performance efficiency Q= quality rate MTBF= mean time between failures MTTR= mean time to repair RE= rate efficiency SE= speed efficiency
Breakdowns-tooling failure, motor failure, etc. Setup and Adjustments-changeover, operator shortage, etc. Small Stops-component jam, sensor blocked, etc. Slow Running-incorrect setting, alignment problem, etc. Startup Defects- rework Production Defects-scrap
