Lean TPM
Total Productive Maintenance is a program for optimizing the effectiveness of manufacturing equipment through eliminating equipment-related losses, such as breakdowns, quality defects and slow changeovers.
The standard definition of TPM is as follows:
- The goal of TPM is to build a robust enterprise by maximizing production system efficiency.
- TPM is a practical shop-floor system to prevent losses before they occur throughout the entire production system life cycle. Its aim is the elimination of accidents, defects, and breakdowns.
- TPM involves all departments, from production to development, sales, and administration.
- Everyone participates in TPM, from top executives to shopfloor employees.
- TPM achieves zero losses through overlapping "small groups" activities.
One of the basic principles of TPM is that operators are the first line of defence against unplanned equipment downtime. Autonomous maintenance, or Operator's Maintenance, assumes that the people who are in daily contact can use their knowledge and skills to predict and prevent breakdowns and other losses.
The most frequently used measurement of equipment effectiveness is Overall Equipment Effectiveness.
