TOTAL PRODUCTIVE MAINTENANCE
INTRODUCTION:
We expect our machines to work without failures, produce high quality output, at the same time consume very less manpower, raw materials, electrical energy, tools/ consumables etc, but this is highly difficult to realize in practice unless they approach is towards identifying the losses and eliminating them. Total productive maintenance, shortly termed as TPM, provides means to achieve and maintain high levels of productivity.
TPM is based on zero loss concept, viz. zero accidents, zero defects and zero breakdowns, which render equipment “effective”.
TPM focuses on improving the Planned Loading Time. The gap (losses) between 100% and actual efficiency can be categorized into 3 categories:
- Availability
- Performance
- Yield (Quality Rate)
Availability losses:
Breakdowns and changeovers indicate situations where the line is not running while it should be.
Performance losses:
Speed losses and small stops/idling/empty positions indicate the line is running, but is not providing the quantity it should.
Yield losses:
Additionally, when the line producing products, there are losses due to rejects and start-up quality losses.
Total productive maintenance:
Aims at getting the most efficient use of equipment.
Establish a total PM system encompassing maintenance prevention, preventive maintenance and improvement-related maintenance.
Involves every employer in the company. It requires the co-operation of equipment designer and engineers, equipment operators and maintenance workers.
Promotes and implements PM small through small-group or team activities.
BRIEF ON 8 PILLARS
AUTONOMOUS MAINTENANCE: (JISHU HOZEN)
Autonomous maintenance is the cleaning, checking, discovering hidden faults and undertaking simple adjustments by the operators, systematically trained through a step by step program. Autonomous management is to prevent
