The Definition of TPM

The Spread of TPM in Japan

How do TPM and TQC Differ?


The Basic Concepts of TPM

1. Maximizing Overall Equipment Effectiveness

2. Autonomous Maintenance
In factory automation, production workers do not have to operate machines themselves. These operators asked to oversee machines can do inspection of the automatic machines every day or week as per a plan and do routine maintenance. Specialist maintenance persons can act as equipment doctors, who periodically do expert diagnostic checks and do the required maintenance.

3. Small Group Activities in Maintenance
Similar to quality circles, zero defect movement groups and Jishu Kanri.

‘Jishu Kanri’ activities in the Japanese steel industry Small group activities being promoted by the industry as a whole
HIDEO SUGISAWA &KAZUO HIROSE
International Journal of Production Research, Volume 15, 1977 - Issue 6, Pages 523-538
The group activities called ‘ Jishu Kanri ’ by foremen and workers in the forefront of production has been actively promoted in the Japanese Steel Industry by establishing a committee for ’ Jishu Kanri’ activities in the Japan Iron and Steel Federation, with the positive cooperation of its member companies. Nearly 8 years have elapsed since the establishment of this committee, and during this period the ability and skill of the group leaders and members in managing group activities and their awareness of problems and solutions have been greatly improved, thereby contributing much to the improvement of quality, attainment of production targets, reduction in the production costs, and improvement of safety.

The Japan Iron & Steel Federation adopted the name "Jishu-Kanri GK) Activities" to generalize the uniqueness of small group activities in this industry. JK activities are defined as "continuous group activities in which individual workers voluntarily organize small groups, select leaders from among themselves, hold discussions on an equal footing, and with their leaders as the nuclei, take up problems at the workshop, set goals for the solution of the problems, and make efforts to achieve the goals with participation by everyone".

Workers' voluntary problem solving activities cover a wide range such as product quality enhancement, efficiency improvement, cost reduction, promoting safety at the workshop, and others. In 1983, ensuring work safety was the top of activity (27.4%). About 90% of the activities in 1993 related to four areas: 
efficiency improvement (30.8%), cost reduction (24.6%), ensuring work safety (19.6%) and product quality enhancement (14.6%).

WHAT IS TPM?

TPM (Total Productive Maintenance) is a holistic approach to equipment maintenance that strives to achieve effectiveness and efficiency in the use of machines by maximizing availability and by maximizing quality output from each machine hour.

The objectives or aims of TPM are:

No Accidents
No Breakdowns
No Small Stops or Slow Running
No Defects



TPM emphasizes proactive and preventative maintenance to maximize the operational effectiveness and  efficiency of equipment. In focusing on productive availability and use of machines, it places  a strong emphasis on involving operators to help maintain their equipment.

The implementation of a TPM program creates a shared responsibility for equipment that encourages greater involvement by plant floor workers in regular cleaning, lubrication and other routine machine upkeep activities. Operators also inform machine condition frequently so that maintenance can be undertaken in timely manner. TPM became effective in many companies in improving productivity (increasing up time, reducing cycle times, and eliminating defects).

8 Pillars of TPM

Autonomous Maintenance

Places responsibility for routine maintenance, such as cleaning, lubricating, and inspection, in the hands of operators.
Gives operators greater “ownership” of their equipment.
Increases operators’ knowledge of their equipment.
Ensures equipment is well-cleaned and lubricated.
Identifies emergent issues before they become failures.
Frees maintenance personnel for higher-level tasks.

Planned Maintenance

Schedules maintenance tasks based on predicted and/or measured failure rates.
Significantly reduces instances of unplanned stop time.
Enables most maintenance to be planned for times when equipment is not scheduled for production.
Reduces inventory through better control of wear-prone and failure-prone parts.

Quality Maintenance

Design error detection and prevention into production processes. Apply Root Cause Analysis to eliminate recurring sources of quality defects.
Specifically targets quality issues with improvement projects focused on removing root sources of defects.
Reduces number of defects.
Reduces cost by catching defects early (it is expensive and unreliable to find defects through inspection).


Focused Improvement

Have small groups of employees work together proactively to achieve regular, incremental improvements in equipment operation.
Recurring problems are identified and resolved by cross-functional teams.
Combines the collective talents of a company to create an engine for continuous improvement.


Early Equipment Management

Directs practical knowledge and understanding of manufacturing equipment gained through TPM towards improving the design of new equipment.
New equipment reaches planned performance levels much faster due to fewer startup issues.
Maintenance is simpler and more robust due to practical review and employee involvement prior to installation.


Training and Education

Fill in knowledge gaps necessary to achieve TPM goals. Applies to operators, maintenance personnel and managers.
Operators develop skills to routinely maintain equipment and identify emerging problems.
Maintenance personnel learn techniques for proactive and preventative maintenance.
Managers are trained on TPM principles as well as on employee coaching and development.


Safety, Health, Environment

Maintain a safe and healthy working environment.
Eliminates potential health and safety risks, resulting in a safer workplace.
Specifically targets the goal of an accident-free workplace.

TPM in Administration

Apply TPM techniques to administrative functions.
Extends TPM benefits beyond the plant floor by addressing waste in administrative functions.
Supports production through improved administrative operations (e.g. order processing, procurement, and scheduling).

Six Big Losses


Unplanned Stops Availability Loss
Tooling Failure, Unplanned Maintenance, Overheated Bearing, Motor Failure There is flexibility on where to set the threshold between an Unplanned Stop (Availability Loss) and a Small Stop (Performance Loss).

Setup and Adjustments Availability Loss
Setup/Changeover, Material Shortage, Operator Shortage, Major Adjustment, Warm-Up Time This loss is often addressed through setup time reduction programs such as SMED (Single-Minute Exchange of Die).

Small Stops Performance Loss
Component Jam, Minor Adjustment, Sensor Blocked, Delivery Blocked, Cleaning/Checking Typically only includes stops that are less than five minutes and that do not require maintenance personnel.

Slow Running Performance Loss
Incorrect Setting, Equipment Wear, Alignment Problem Anything that keeps the equipment from running at its theoretical maximum speed.

Production Defects Quality Loss
Scrap, Rework Rejects during steady-state production.

Reduced Yield Quality Loss
Scrap, Rework Rejects during warm-up, startup or other early production.

Systematic Industrial Maintenance to Boost the Quality Management Programs

Adnan Bakri, Mohd Al-Fatihhi Mohd Szali Januddi
Springer Nature, 04-Jun-2020 - Technology & Engineering - 78 pages

This book discusses the main quality management (QM) programs and their possible integration into systematic industrial maintenance (SIM). Unlike traditional engineering maintenance books, it not only explains the theory but also provides practical examples of the integration of QM and SIM programs. It also includes reference sources, making it useful for readers wanting to explore specific areas in more depth.
Chapter 1 introduces various aspects of the main quality management (QM) programs, including total quality management (TQM), just-in-time (JIT) and lean manufacturing (Lean). Subsequently, it examines the relation of quality and maintenance. Chapter 2 reviews the concepts of systematic industrial maintenance (SIM) and the application of quality control (QC) tools. Chapter 3 offers an overview, historical perspective and trends in industrial maintenance techniques. Chapters 4, 5, 6, 7, 8 and 9 focus on topics related to schedule-based maintenance, condition-based maintenance, reliability-based maintenance, computerized-based maintenance, risk-based maintenance and total productive maintenance. Covering the theory of each of these types of SIM, the chapters also explain their real-world application in QM and highlight their merits and weaknesses in the context of supporting QM.
