What is TPM (Total Productive Maintenance)?-TPM pillars
Do you know that there is a strategy named TPM that should be implemented in manufacturing firms for direct reduction in customer complaints, workplace benefits and manufacturing cost so that the productivity and quality of product should be increased. Let firstly know what exactly TPM( Total Productive Maintenance) is?
What is Total Productive Maintenance (TPM)?
Total Productive Maintenance (TPM) is a maintenance philosophy and methodology that focuses on maximizing the productivity and efficiency of manufacturing equipment by involving all employees in the maintenance process. The goal of TPM total productive maintenance is to achieve zero equipment breakdowns, defects, and accidents, leading to improved overall equipment effectiveness (OEE), reduced downtime, increased equipment reliability, improved product quality, and a safer workplace. TPM is based on the principle that everyone in the organization, from the top management to the shop floor operators, has a role to play in maintaining equipment and improving production processes. The key pillars of TPM include autonomous maintenance, planned maintenance, and quality maintenance, and the TPM approach emphasizes employee training and engagement, continuous improvement, and a proactive approach to maintenance.
Traditional TPM pillars
The “TPM pillars” is a framework that outlines the key elements required to implement Total Productive Maintenance (TPM) effectively. The 8 pillars are as follows:
Autonomous Maintenance: This pillar involves empowering operators to take responsibility for the routine maintenance of their equipment. This includes cleaning, lubrication, inspection, and minor repairs.
Planned Maintenance: This pillar involves developing a comprehensive maintenance plan for all equipment. This plan includes periodic inspections, preventive maintenance activities, and equipment overhauls.
Quality Maintenance: This pillar involves improving equipment and process reliability to ensure consistent product quality. This includes identifying and eliminating defects, reducing variation in the manufacturing process, and improving process control.
Training and Education: This pillar involves providing employees with the training and education they need to effectively perform their job duties. This includes technical training, safety training, and leadership development.
Safety, Health, and Environment: This pillar involves ensuring a safe and healthy workplace for all employees. This includes identifying and addressing safety hazards, promoting safety awareness, and complying with environmental regulations.
Office TPM: This pillar involves applying TPM principles and practices to office and administrative processes. This includes improving office efficiency, reducing errors, and optimizing workflow.
Early Equipment Management: This pillar involves ensuring that new equipment is designed for reliability and maintainability. This includes involving maintenance and production personnel in the equipment design process and performing equipment failure mode and effects analysis (FMEA) to identify potential problems.
TPM in Administration: This pillar involves applying TPM principles and practices to administrative and management processes. This includes developing and implementing systems for continuous improvement, standardizing work processes, and promoting employee engagement and empowerment.
The 5S Methodology
Sort: This involves removing all unnecessary items from the work area and keeping only what is essential to the work process. Unneeded items are either thrown away or moved to storage areas.
Set in Order: This involves organizing the work area in a way that promotes efficiency and productivity. Tools, equipment, and materials are arranged in a logical sequence, with the most frequently used items within easy reach.
Shine: This involves cleaning and maintaining the work area to ensure a safe and productive environment. Equipment and surfaces are regularly cleaned, and maintenance issues are addressed promptly.
Standardize: This involves establishing standard procedures for maintaining the work area and performing work tasks. Standardization ensures consistency and reduces the risk of errors and accidents.
Sustain: This involves maintaining the gains achieved through the previous steps by creating a culture of continuous improvement. Employees are encouraged to identify and address problems, and regular audits are conducted to ensure compliance with established procedures.
Steps to Implement Total Productive Maintenance (TPM)
Implementing Total Productive Maintenance (TPM) can be a challenging process, but it is critical for manufacturing companies that want to achieve sustainable improvements in their equipment reliability, production efficiency, and product quality. Here are some steps that companies can take to implement TPM effectively:
Create a TPM Team: Establish a dedicated team of employees responsible for implementing TPM. The team should include representatives from all areas of the organization, including management, production, maintenance, quality, and safety.
Establish a TPM Program: Develop a comprehensive TPM program that outlines the goals, objectives, and strategies for implementing TPM. The program should include a clear roadmap for TPM implementation, including timelines, milestones, and resource requirements.
Develop a TPM Plan: Create a detailed TPM plan that outlines the specific activities, tasks, and responsibilities required to implement TPM. The plan should include a breakdown of the different TPM pillars, including autonomous maintenance, planned maintenance, and quality maintenance, and should identify the tools and techniques required for each pillar.
Provide Training: Train employees on the principles and practices of TPM, including how to identify and address equipment problems, how to conduct autonomous maintenance, how to perform planned maintenance, and how to improve quality and safety.
Engage Employees: Involve employees in the TPM process by encouraging them to identify and report equipment problems, participate in autonomous maintenance activities, and suggest improvements to production processes.
Monitor and Measure Progress: Monitor and measure progress against the TPM program and plan. Use key performance indicators (KPIs) to track equipment reliability, production efficiency, and quality, and use this data to identify areas for improvement.
Continuously Improve: Continuously improve the TPM program by reviewing and updating it on a regular basis. Encourage employee feedback and suggestions for improvement, and use this feedback to refine the TPM program and plan over time.
