Total Productive Maintenance (TPM) aims for zero defects, breakdowns, and losses through total employee participation in maintenance to increase productivity. TPM is productive maintenance that seeks to eliminate downtime through breakdowns and setups, speed losses from idling or reduced speeds, and defects from rework or unstable production, by maintaining equipment, operating conditions, restoring deterioration, improving skills, and identifying hidden problems. TPM requires maintaining basic equipment, operating conditions, restoring deterioration, correcting design weaknesses, improving technical skills, and exposing hidden defects.
Total productivity maintenance technique
- 2. TPM : Zero sum approach • Zero defects • Zero breakdowns • Zero losses
- 3. Total productivity maintenance Total Productive Maintenance is productive maintenance involving total participation for increased productivity.
- 4. Why TPM: Downtime (a) Breakdowns due to equipment failure. (b) Setup and adjustment e.g . exchange of die injection moulding machines etc.
- 5. Why TPM - Speed losses (a) Idling and minor stoppages e.g. abnormal operations of sensors (b) Reduced speed e.g. discrepancies between design and actual speed of equipment
- 6. Why TPM - Defects (a) Defect in process and rework ( scrap and quality defects requiring repair ) (b) Reduced yield between machine startup and stable production.
- 7. Requirements for TPM Maintain basic equipment conditions Maintain operating conditions Restore deterioration Correct design weaknesses Improve technical skill Expose hidden defects
