Total Productive Maintenance (TPM) is a type of productive maintenance that each employee performs in small groups. TPM is general organization-wide equipment maintenance.
TPM anticipates and eliminates unnecessary downtime to increase equipment productivity. One of the key components of the lean continuous improvement process, TPM can raise a machine's capacity, lower maintenance costs, significantly minimise the need for extra work, and boost a company's production and profits. Lower inventory levels are made possible by these TPM advantages since unscheduled downtime is not required.
By putting the emphasis on enabling operators to assist in equipment maintenance, it minimises the roles of production and maintenance. By raising uptime, cutting cycle times, and getting rid of defects, a TPM programme can be very effective in boosting productivity. It also encourages increased involvement from plant floor personnel.
To achieve maintenance-free operations, TPM focuses on the staff and implements the three following practices.

The Foundation of TPM is 5S
The traditional approach to TPM was created in the 1960s and consists of eight supporting activities, sometimes known as pillars, and 5S as a foundation.
5S is where TPM begins. When the workplace is disorganised, issues cannot be noticed clearly. The staff is better able to identify issues when the workplace is organised and cleaned. The first step in solving problems is to make them evident.
Sorting and categorising goods as essential, significant, commonly used, or not needed at the moment is known as Seiri. It is possible to salvage unwanted objects. Items that are essential should be kept close at hand for use, and items that won't be needed anytime soon should be put elsewhere.
1. Equipment Reliability: TPM aims to improve equipment reliability by reducing breakdowns, defects, and unplanned downtime. The goal is to achieve zero breakdowns and ensure that equipment is always available for production.
Equipment reliability is a crucial aspect of Total Productive Maintenance (TPM). TPM emphasizes the improvement of equipment reliability as a means to maximize overall equipment effectiveness (OEE) and enhance operational efficiency. Here's how equipment reliability is addressed within TPM:
a. Preventive Maintenance: TPM emphasizes proactive maintenance practices to prevent equipment failures. Preventive maintenance activities are planned and performed based on equipment condition, usage, and performance data. This includes regular inspections, lubrication, cleaning, adjustments, and replacement of worn parts. By conducting preventive maintenance, organizations aim to identify and address potential issues before they lead to equipment breakdowns or disruptions.
b. Condition Monitoring: TPM incorporates condition monitoring techniques to assess the health and performance of equipment. This may involve monitoring parameters such as temperature, vibration, noise, pressure, or other relevant factors. Condition monitoring helps identify potential issues or deviations from normal operating conditions, enabling timely intervention before major problems occur.
c. Equipment Standardization and Simplification: TPM emphasizes standardization and simplification of equipment design and operation. By reducing variations and complexity, organizations can enhance equipment reliability and minimize the potential for failures due to operational errors or compatibility issues.
d. Quick Changeovers (SMED): TPM incorporates Single Minute Exchange of Die (SMED) techniques to reduce changeover times between product runs or equipment setups. Efficient changeover processes minimize the risk of errors, reduce downtime, and contribute to equipment reliability by ensuring smooth transitions between production runs.
e. Root Cause Analysis and Problem Solving: TPM encourages the use of root cause analysis techniques to identify and eliminate the underlying causes of equipment failures or performance issues. Cross-functional teams are formed to investigate problems, analyze data, and implement corrective actions to prevent recurrence. By addressing root causes, organizations aim to improve equipment reliability and prevent similar issues from arising in the future.
By focusing on preventive maintenance, operator involvement, condition monitoring, standardization, and problem-solving, TPM aims to improve equipment reliability. The ultimate goal is to reduce breakdowns, unplanned downtime, and defects, leading to increased productivity, better product quality, and improved overall equipment effectiveness.
2. Autonomous Maintenance: TPM encourages operators and frontline maintenance personnel to take responsibility for the routine care and maintenance of equipment. Operators are trained to perform simple maintenance tasks, inspections, and minor repairs, ensuring that equipment remains in optimal condition.
Autonomous Maintenance is a key pillar of Total Productive Maintenance (TPM) that focuses on empowering operators and frontline maintenance personnel to take ownership of the routine care and maintenance of equipment. It involves training and involving operators in activities to improve equipment reliability, cleanliness, and overall performance. The goal of Autonomous Maintenance is to enhance equipment effectiveness, reduce breakdowns, and foster a proactive maintenance culture within the organization.
