Total Productive Maintenance (TPM) manufactures activities that are productive and implemented by everyone in the organization. The main focus of TPM is to maximize the overall equipment effectiveness of the asset which is utilized to produce the goods and services.
TPM focus on establishing good maintenance practice through five goals:
• Improving equipment effectiveness
TPM wants to insure the equipment can perform to design specifications. The effectiveness of facilities can be identified and examined by downtime losses, speed losses and defect losses.
• Improving maintenance effectiveness
TPM focus on maintenance activities which are carried out on the equipment are performed in a cost effective way.
• Early equipment management and maintenance prevention
This goal of TPM is to reduce maintenance activities required by the equipment. It involves the identification nature and preventive maintenance level which are required for the equipment, the creation standards for condition-based maintenance, and the respective responsibilities for both maintenance and operating staff.
• Training all staff in relevant maintenance skills
The maintenance and operating staff need to have all the necessary skills to carry out TPM. TPM emphasizes appropriate and continuous training.
• Involving Operators in Routine Maintenance
This goal is to let operators find maintenance tasks related to the equipment they perform. These tasks are about 10-40% of routine maintenance tasks performed on the equipment. Formerly engaged in these activities, maintenance resources can be redeployed in more advanced maintenance activities such as reliability focused maintenance activities or predictive maintenance.
[...] Thus a lot of data was collected about equipment during the time. Then the data was fed back into the design, procurement, and equipment management In the 1970s, TPM focused on achieving Productive Maintenance efficiency through a comprehensive system based on total employee participation and the respect for individuals. At this time, was added in front of Productive Maintenance (PM). In the mid-1970s, the Japanese began to teach TPM strategies internationally and were recognized for their results. Today TPM is focus on supporting a company's full utilization of its assets. [...]
[...] It differentiates 4 maintenance types: Breakdown maintenance: The maintenance is done when the item has a problem. If we take the example of a car tire, the breakdown maintenance would be a change of the tire when one burst. Preventive maintenance: The maintenance is a regular check (usually daily) of the item. In the tire example it would be the checking of the air pressure. Corrective maintenance: This kind of maintenance focuses on the replacement of the parts that might break in the short term., in order to avoid such a breakdown. [...]
[...] Conclusion Total Productive Maintenance (TPM) is a concept to maintenance plants and equipment. It focuses on establishing good maintenance practice through five goals. The main focus of TPM is to maximize the overall equipment effectiveness of the asset which is utilized to produce the goods and services. It can increase productivity, product quality, safety, and employee morale, at the same time, and reduce costs and inventory level. Thus TPM is very important to business. The 7 pillars method makes it easier for a company to identify the way to implement TPM. [...]
[...] Therefore, by differentiating different types of maintenance, the maintenance team can better analyze where to focus the effort. It is clear that a good company would try to have the most of it maintenance in the last types, to avoid breakdowns. The fourth pillar is the quality maintenance. It is the application of a Six Sigma project to the maintenance field. The focus is on eliminating the defects resulting from a bad maintenance of the machines. In order to estimate the number of defects and to find a way to solve them, the maintenance team has to gather two kinds of data: the information relative to the customer-end defects, and the information relative to the in-house defects. [...]
[...] Anonymous 2005B) Total Productive Maintenance: From 5S to the 7 pillars The Total Productive Maintenance theory has been developed and analyzed by several authors, who estimated that it implementation in a company had to go trough a certain number of pillars, usually between 5 and 8. In this study, we decided to analyze a version of TPM built with seven pillars on the 5S base: www.plant-maintenance.com/articles/tpm_intro.shtml) Implementing the 5S in the company is a requirement before going further in the TPM: Seiri (Organisation): There is no need to keep at the workplace every item.
