Father Of TPM
Total Productive MaintenanceTotal• All employees • All Departments• All machines
Productive• Actions to reduce the losses
Maintenance• Keep as good as NEW
ZERO - Accident - Breakdown - Change over - Defect
To improve the useful life Period
Pillars of TPM
Autonomous Maintenance (JISHU HOZEN)
C-CleaningL-LubricationR-RetighteningI -Inspection
Steps in JISHU HOZEN
Focused Improvement (Kobetsu Kaizen)•OEE
•Transformation cost
Why losses occur?• Operation exceeds its standard timing • Non-value adding operation is performed• Machine is idle when it should have given the rated output• Machine and or man do not give the rated output• Additional time, money and energy than the specified norms
Understanding Downtime
OEE – Overall Equipment Effectiveness
OEE = Availability X Performance X Quality
Availability = 77% Performance = 95% Quality = 92%
77% x 95% x 92%
Planned Maintenance• Recoding present status• Improve weakness.• Information system• Preventive maintenance• Predictive maintenance system
Quality Maintenance• Detect the defect after it has been produced
• Prevent defects from being produced in the first place
EDUCATION AND TRAINING•A current state analysis•Develop a training plan• Implement and evaluate the plan
Safety, Health & Environment
• Safety zero accidents
• Health zero overburden (physical and mental stress and strain on employees)
• Environment zero pollution
Office TPM
• Eliminating losses in the administrative systems across the whole organization and into the extended supply chain• Cost reductions in the organization's overheads as well as supporting
improvement
Steps in introduction of TPM in a organization
