What factory isn’t looking for ways to make maintenance operations more efficient? To improve the production process and promote continuous improvement on the factory floor, it is essential to reduce machine downtime, and the costs associated with malfunctions. The lean TPM method, with its 8 pillars, helps shop floor staff and management create a working environment where maintenance, quality, safety and efficiency are seamlessly integrated into everyday operations.
TPM meaning
Lean TPM (Total Productive Maintenance) is a maintenance management method that originated in Japan, particularly in automotive companies such as Toyota. The aim is to maximize the production equipment productivity by minimizing disruptions, unplanned stoppages and maintenance costs.
TPM is based on the fundamental principle of lean management, which involves eliminating waste, optimizing processes and improving quality.
The benefits of lean TPM for factory floors
Implementing lean TPM on the factory floor delivers a number of significant benefits:
- Reduced downtime through regular maintenance, enabling more stable, continuous production.
- Better equipment availability, enabling increased production capacity without having to invest in expensive new equipment.
- Lower maintenance costs through prevention.
- Improved quality: TPM contributes to the manufacture of higher-quality products by ensuring that equipment operates correctly. This reduces touch-ups and rejects.
The 8 pillars of lean TPM
TPM is based on eight pillars, whose main focus is to proactively improve machine reliability. Their implementation is essential to guarantee the method’s sustainability.
Autonomous maintenance
Also known as self-maintenance, autonomous maintenance involves delegating certain maintenance tasks to operators and production teams. Operators are trained to carry out basic maintenance activities, such as cleaning, lubrication, screw tightening and visual inspection. The aim is to get them involved and make them responsible for the cleanliness, reliability and lifespan of the equipment.
Focused improvement
The aim of the principle is to resolve maintenance issues proactively. This might include design modifications, process adjustments, improvements to maintenance procedures, etc.
The production staff identify equipment-specific problems, and seek solutions to get rid of them permanently, and enable continuous improvement in equipment reliability.
Scheduled maintenance
It is strongly recommended that preventive maintenance activities are carried out according to a set schedule (and not to wait until the breakdown occurs before acting!). Lubrication, replacement of parts that show wear, regular inspections, etc… by planning these activities, companies can minimize unplanned downtime, prevent breakdowns, extend equipment life and reduce maintenance costs. An effective way of ensuring predictive maintenance is carried out properly, is to bring on board CMM (computer-aided maintenance management) software.
Training and education
In-service training enables operators to acquire specific maintenance-related skills, such as detecting early signs of failure, basic repair, and understanding failure patterns. This expertise enhances maintenance efficiency and equipment reliability.
Safety, health and environment
It is essential to ensure worker safety, improve working conditions, and minimize the environmental impact of operations. TPM promotes sound working practices, a safety culture, and responsible management of waste and resources.
Quality maintenance
The aim of quality maintenance is to ensure that equipment operates in a way that produces high-quality products. Inadequate maintenance can lead to uneven product quality, which can be costly in terms of rejects and touch-ups.
Early equipment maintenance
Early equipment maintenance is the traditional pillar of TPM. It’s all about ensuring that your equipment is in good working order and reliable. This includes early detection of signs of failure, repairs, replacement of parts, and improvements to extend equipment life.
Office TPM
Lean TPM is not confined to the shop floor: it can also be applied in office environments. Here,TPM aims to improve the efficiency of administrative processes, reduce errors, eliminate redundant tasks, and optimize human resources management.
In short, the TPM method, used in a lean management context, aims to optimize maintenance management to maximize productivity, reduce costs and improve quality. It combines 8 pillars. The method relies on the participation of each team, and encourages continuous improvement, making it a powerful approach for production shop floors.
