Total Productivity Maintenance
• Zero defects• Zero breakdowns• Zero losses
TPM : Zero sum approach
Total Productive Maintenance is productive maintenance involving total participation for increased productivity.
Total productivity maintenance
(a) Breakdowns due to equipment failure. (b) Setup and adjustment e.g . exchange of die injection moulding machines etc.
Why TPM: Downtime
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
Why TPM - Defects
(a) Defect in process and rework ( scrap and quality defects requiring repair ) (b) Reduced yield between machine startup and stable production.
Requirements for TPM
Maintain basic equipment conditions Maintain operating conditions Restore deterioration Correct design weaknesses Improve technical skill Expose hidden defects
