This document provides an overview of Total Productive Maintenance (TPM). TPM aims to eliminate losses like equipment downtime, defects, and accidents by involving machine operators in preventative maintenance. Its objectives are to create a safer work environment, improve quality, reliability, and financial performance. TPM measures effectiveness using Overall Equipment Effectiveness (OEE) and addresses six major losses: availability, performance, and quality losses. It works by establishing pillars like autonomous, planned, and quality maintenance.

3. What’sT P M
• TPM wasdeveloped in the 1970's as amethodof involving
machineoperators in the preventive maintenanceof their
machines
– a reaction to increasing specialization and centralization of the maintenance
function that had createddivision-of-labor barriers between operators and the
maintenance of their machines and equipment.
– Also creating a sense of ownership in workers with Autonomous Maintenance

4. Objectives ofT P M
• Theoverriding objective ofTPMis the elimination ofLOSSES. Losses, or
waste, includes equipment downtime, defects, scrap, accidents, wasted energy,
and laborinefficiency.
• TPM was introduced to achieve some of the following important objectives:
– Safer working environment, Job security
– Producing goods with improved quality and machinereliability
– Improvedfinancial performance
– Producea low batch quantity at the earliest possible time.
– Goods send to the customers must benon defective

Before 1 Severe problem occured, there were 300 minor and 29 major problems to
handle.

TPM is a tool which addresses potential signs of machine break-downs and is therefore
an important instrument to prevent total machine crashes.

6. Concept ZERO
• Thegoal of TPM isto driveallwastetozero: ZeroAccidents,Zero
Defects,ZeroBreakdowns.
• TheConcept of Zero is built upon Poka-Yoke, in the design of the process to make
it impossible to makeand pass on defects.
• Poka-Yoke concepts are also commonlyapplied to equipment to prevent
breakdowns.
• Poka (Mistakes), Yokeru(Avoid) orMistake Proofing (Japanese Term)

7. Performance Measure and 6 Losses
• Overall Equipment Effectiveness (OEE)is the performance measureof TPM.
• Thus factors affecting OEE/ TPM:
• Availability
• Performance
• Quality
– Associated 6 big losses are:
• Availability Losses: Breakdown losses causedby the equipment; Set-up
and adjustment losses
• Performance Losses: Minor stoppage losses; Speed losses
• Quality Losses: Quality defect and rework losses; Yield losses
