What is Total Productive Maintenance?

Total Productive Maintenance (TPM) is a comprehensive approach aimed to achieve perfect production with zero breakdowns, zero defects, and zero accidents. Unlike traditional maintenance methods that primarily involve maintenance personnel, TPM emphasizes the active involvement of all employees, from operators to managers, in maintaining and improving equipment.

TPM focuses on proactive and preventive maintenance to enhance equipment reliability and efficiency. It aims to create a culture where maintenance is considered a key part of daily operations rather than an afterthought. This involves routine inspections, cleaning, lubrication, and minor repairs performed by the equipment operators. By doing so, TPM helps to identify potential issues before they lead to significant problems, thereby reducing unplanned downtime and extending the lifespan of the equipment.

How to Calculate TPM?

Calculating Total Productive Maintenance (TPM) involves understanding and measuring your machinery's Overall Equipment Effectiveness (OEE). OEE is a key performance indicator that combines three critical aspects of equipment performance: Availability, Performance, and Quality. Here's how you can calculate each component and the overall OEE:

Availability: This represents the percentage of time the equipment is operational and available for production.

‍

Formula:

Availability = (Operating Time / Scheduled Operating Time) x 100

‍

Example:

If your equipment was scheduled to operate for 8 hours (480 minutes) but only ran for 7 hours (420 minutes) due to downtime, the Availability would be:

‍

Availability = (420/480) x 100 = 87.5%

Performance: This refers to the rate at which the equipment produces good quality parts compared to its ideal speed.

‍

Formula:

Performance = (Actual Output / Theoretical Output) x 100

‍

Example:

If the equipment's ideal cycle time is 1 minute per unit, and it produces 400 units in 420 minutes, then the theoretical output is 420 units.

‍

Performance = (400/420) x 100 = 95.2%

Quality: This represents the percentage of good-quality parts produced compared to the total number of parts produced.

‍

Formula:

Quality = (Good Units / Total Units Produced) x 100

‍

Example:

If out of 400 units produced, 380 units are of good quality and 20 units are defective, the Quality would be:

‍

Quality = (380/400)x100 = 95%

Here's how you can calculate each component and the overall OEE:

‍

Formula: OEE = Availability x Performance x Quality

‍

OEE = 87.5 x 95.2 x 95 = 79.1%

‍

An OEE of 79.1% indicates that your equipment produces 79.1% of its potential output, considering downtime, speed losses, and quality defects.

By regularly calculating and analyzing OEE, you can identify areas for improvement in your maintenance processes and work towards maximizing your equipment's productivity.

5S: What Does Each "S" Stand For?

The 5S methodology is a foundational component of Total Productive Maintenance (TPM) and lean manufacturing. Originating from Japan, 5S focuses on workplace organization and standardization to improve efficiency and safety. Each "S" in the 5S system represents a step in the process. Here's what each "S" stands for and how it contributes to a more productive work environment:

Sort involves evaluating all items in a workspace and removing unnecessary items. Unnecessary tools, materials, and outdated procedures create clutter and hinder productivity. Dispose of what's not needed through recycling, selling, or proper disposal channels.

Now that you've decluttered, it's time to organize the remaining items efficiently.  Designate specific storage locations for tools, materials, and equipment.  Use clear labels and visual cues to ensure everything is easy to find and put away. This eliminates wasted time searching for what you need.

A clean and well-maintained workspace fosters a sense of pride and ownership among employees.  Establish cleaning routines and assign responsibilities for keeping the work area organized and free of dirt, debris, and safety hazards.  A clean environment also promotes better equipment visibility, allowing for early detection of potential problems.

Once you've established a clean and organized work area, the key is to maintain it.  Develop standardized procedures for sorting, arranging, cleaning, and maintaining the workspace.  This ensures everyone is on the same page and helps to prevent backsliding into clutter and inefficiency.

The final "S" emphasizes the importance of ongoing commitment.  Integrate 5S principles into your company culture and daily routines.  Conduct regular audits to ensure everyone is adhering to the standards.  Encourage suggestions for improvement and celebrate successes in maintaining a streamlined workspace.

The 5S methodology is a simple yet powerful tool that helps organizations create a well-organized, efficient, and safe work environment. Integrating 5S into your Total Productive Maintenance (TPM) program sets a solid foundation for achieving operational excellence.

Total Productive Maintenance Workflow

Implementing Total Productive Maintenance (TPM) involves a structured workflow that guides organizations through the essential steps to achieve optimal equipment performance and reliability. Here's a detailed breakdown of the TPM workflow:

The first step is to initiate the TPM program. This involves gaining commitment from top management and establishing a clear vision and objectives for the TPM initiative. It's crucial to communicate the benefits of TPM to all employees and ensure their active participation.

• Develop an Autonomous Maintenance Program: Empower operators to take ownership of basic equipment care through tasks like cleaning, lubrication, and visual inspections. This fosters a sense of responsibility and helps identify potential issues early on.

‍

• Develop a Scheduled Maintenance Program: Create a comprehensive plan based on equipment specifications and usage data for scheduled maintenance activities. This proactive approach prevents breakdowns and ensures optimal performance.

• Training and Education: It is crucial to equip your workforce with the necessary knowledge and skills. Train operators and maintenance personnel to ensure everyone understands their roles and responsibilities within the TPM framework.

‍

• Information Systems: Implement data collection and analysis systems. This allows you to track key performance indicators (KPIs), identify improvement areas, and measure your TPM program's effectiveness.

When acquiring new equipment, prioritize reliability and establish proper maintenance procedures from the start. This proactive approach sets the stage for long-term equipment effectiveness.

The final step is to continuously practice the 8 pillars of TPM, which are essential for sustaining the program and achieving long-term success. These pillars include:

1. Autonomous Maintenance
2. Focused Improvement
3. Planned Maintenance
4. Early Equipment Management
5. Quality Maintenance
6. Training and Education
7. TPM in Administration
8. Safety, Health, and Environment

8 Pillars of Total Productive Maintenance

We've established that Total Productive Maintenance (TPM) is a comprehensive approach for achieving peak equipment performance. But what are the building blocks that make it work? Enter the eight pillars of TPM, a comprehensive framework that guides a collaborative and proactive approach to equipment care. Let's delve into each pillar and explore how it contributes to overall equipment effectiveness (OEE):

Autonomous Maintenance is the first pillar of Total Productive Maintenance (TPM), emphasizing the involvement of machine operators in maintaining their equipment. This approach fosters a sense of ownership and responsibility among operators, leading to better equipment performance and reliability.

But why empower operators?

• Frontline Expertise: Operators are intimately familiar with their equipment. They witness its daily operation and can often identify subtle changes in performance that might go unnoticed by others.

‍

• Early Detection: By performing routine care tasks like cleaning, lubrication, and simple visual inspections, operators can detect potential issues early on, preventing them from escalating into bigger problems.

‍

• A Sense of Ownership: Empowering operators to care for their equipment fosters a sense of responsibility and ownership. This leads to a more invested workforce and a proactive approach to equipment maintenance.

What does Autonomous Maintenance involve?

This pillar focuses on training operators to perform a specific set of tasks, typically categorized into three areas:

• Basic Cleaning and Inspection: This might involve wiping down equipment, checking for leaks or loose parts, and ensuring proper lubrication levels.

‍

• Operational Monitoring: Operators become attuned to their equipment's sounds, vibrations, and overall performance. Any deviations from the norm could signal a potential issue.

‍

• Simple Adjustments and Minor Repairs: Operators are trained to perform basic adjustments and minor repairs within their designated scope.

The Power of Partnership

Autonomous Maintenance isn't about replacing the role of maintenance personnel. It's about creating a collaborative partnership between operators and maintenance teams. By empowering operators to become the "eyes and ears" of equipment care, you can build a stronger foundation for achieving overall equipment effectiveness and maximizing the performance of your production system.

Focused Improvement, often called Kaizen, is the second pillar of Total Productive Maintenance (TPM). Kaizen is a Japanese term that means "continuous improvement." This pillar emphasizes the importance of small, incremental changes that collectively lead to significant efficiency, quality, and productivity improvements. Here's an in-depth look at Focused Improvement and its key components:

How Does Kaizen Work in TPM?

The core of Kaizen in TPM lies in creating a culture of continuous improvement that empowers everyone to identify and address areas for improvement. This can involve:

• Identifying Problems and Waste: Employees are encouraged to look for inefficiencies, bottlenecks, and areas where equipment performance can be optimized. This might involve analyzing data, observing processes, and soliciting colleague feedback.

‍

• Brainstorming Solutions: Once a problem or area for improvement is identified, teams brainstorm potential solutions. This collaborative approach encourages diverse perspectives and fosters creative thinking.

‍

• Implementing and Testing Changes: The most promising solutions are then implemented on a small scale to test their effectiveness. This allows for adjustments and refinements before wider rollout.

‍

• Standardization and Sharing: If a change proves successful, it becomes a standardized practice. Sharing successful Kaizen initiatives across departments fosters a culture of continuous improvement and allows everyone to learn from each other's successes.

The Power of Small Steps

Focused Improvement (Kaizen) is a powerful tool for unlocking the full potential of your equipment and workforce. By embracing small, continuous improvements, you can achieve significant results and build a culture of innovation that propels your organization toward operational excellence.

Planned Maintenance is the third pillar of Total Productive Maintenance (TPM). This pillar focuses on scheduling and performing maintenance activities proactively to prevent equipment failures and unplanned downtime. By systematically planning and executing maintenance tasks, organizations can ensure that equipment operates at peak efficiency and reliability.

Early Equipment Management is the fourth pillar of Total Productive Maintenance (TPM). This pillar focuses on setting the stage for long-term equipment success right from the start. When acquiring new equipment, prioritize reliability and establish proper maintenance procedures from the get-go. This proactive approach ensures your new equipment is integrated seamlessly and performs optimally throughout its lifecycle.

The goal is to prevent defects from occurring. This pillar emphasizes techniques like defect prevention, Poka-Yoke (mistake-proofing), and quality control processes throughout production. Focusing on quality from the outset minimizes the need for rework and scrap, ultimately boosting production efficiency.

Equipping your workforce with the necessary knowledge and skills is crucial for successful TPM implementation. Conduct comprehensive training sessions to ensure all employees understand TPM principles and their roles in the process. Operators gain the knowledge to perform basic maintenance tasks, while maintenance personnel are equipped with advanced techniques to handle more complex issues.

While TPM (Total Productive Maintenance) often focuses on the shop floor, its reach extends far beyond the physical equipment. The seventh pillar, TPM in Administration, emphasizes the importance of applying the core principles of TPM to administrative functions as well.

A Key Role Often Overlooked

The administrative department plays a critical role behind the scenes, keeping the production process running smoothly.  Like the rest of the production teams and processes, the management and administrative functions are also subject to productivity improvement. This includes identifying and eliminating losses within their tasks and contributing to the plant's overall performance.

Why TPM in Administration?

Traditional administrative processes can be riddled with inefficiencies, leading to wasted time, errors, and unnecessary delays. TPM in Administration tackles these issues by promoting:

• Streamlined Processes: Analyze and optimize administrative workflows to eliminate unnecessary steps and redundancies. This could involve implementing digital solutions, automating tasks, and standardizing procedures.

‍

• Improved Communication: Ensure clear and efficient communication channels exist between departments. This fosters collaboration and reduces the risk of errors due to miscommunication.

• Data Integrity: Implement processes to ensure the accuracy and reliability of administrative data. This data is crucial for informed decision-making across the organization.

‍

• Continuous Improvement: Like in the production environment, cultivate a culture of continuous improvement within administrative functions. Encourage employees to identify and suggest ways to streamline processes and eliminate waste.

The eight pillars of Total Productive Maintenance (TPM) work together to create a holistic equipment care and optimization approach. But at the core of this philosophy lies the eighth pillar: Safety, Health, and Environment (SHE). This vital pillar ensures that the pursuit of production efficiency never comes at the cost of employee well-being or environmental responsibility.

SHE: A Threefold Focus

The SHE pillar emphasizes three key areas:

• Safety: Creating a safe work environment is paramount. This involves identifying and mitigating potential hazards, implementing safety protocols, and promoting a culture of safety awareness among all employees.

‍

• Health: The physical and mental well-being of your workforce is crucial. This pillar focuses on ergonomics, preventing work-related injuries and illnesses, and promoting healthy work practices.

‍

• Environment: TPM recognizes the importance of minimizing the environmental impact of your production processes. This includes practices like waste reduction, energy conservation, and responsible resource use.
