Glossary

Activity Board:

A statistics board created by each PM group to enhance communication among operators, foster a shared understanding, and display the group's performance to other frontline staff.

Automation:

The adoption of automated equipment to eliminate and streamline various forms of manual labor through mechanical, electrical, pneumatic, hydraulic, or computer-controlled systems.

Autonomous Maintenance:

Operators gradually take steps to identify the optimal conditions for operations and production. This involves establishing essential equipment requirements, which ultimately leads to a setting where autonomous management can thrive.

Autonomous Maintenance Audit:

At the conclusion of each step, frontline managers and engineers conduct an audit of PM regular activities. This process involves assessing the condition of the equipment as well as evaluating the performance of each operator.

Autonomous Maintenance Standards:

The daily maintenance standards for operators, described in step 5, include a mix of cleaning and lubricating guidelines from step 3, along with the categorized inspection standards outlined in step 4.

Benchmark:

The opening conditions of the main indices measured before the start of TPM activities in conjunction with the six major losses and PQCDSM, which are used to estimate operating and production growth.

CAPD Cycle:

A sequence of corrective actions in TPM: Check (C), Act (A), Plan (P) and Perform (D), which must work when planning a specific autonomous maintenance program.

Chronic Loss:

The gap between the actual effectiveness of the equipment and its optimal value when the same damage recurs in a narrow range of occurrence.

Computerization:

The application of computers in eliminating and facilitating various types of manual labour as well as conventional control systems of devices.

Defective:

A product or workpiece that does not meet the specified quality control standards.

Forced Deterioration:

The deterioration of a part of a device or its part that progresses faster than its inherent deterioration characteristics due to certain human performance.

Full-Time Maintenance:

The maintenance activities carried out by the maintenance department as opposed to autonomous maintenance by the operators.

Hidden Defects:

Defects in a device or part thereof that are invisible for certain physical reasons or remain undetected due to a lack of human vision or adjustment.

Identification Tag:

A label that is firmly hung or attached to problematic areas of equipment to clearly indicate and record the minimum information required in relation to an identified problem and the location, remedial action taken and the results of that action.

Just In Time(JIT):

A condition that ensures that the required quantities of necessary materials are available whenever they are needed.

Kanban:

A label or plate containing the minimum information required for the workpieces transported between processes and for the raw materials purchased.

Lubrication Standards:

The operator’s work standards for regular lubrication shall be preliminarily established in Step 3 after the completion of the overall lubrication inspection to maintain proper lubrication of the equipment and shall be revised in relation to the corrective action taken.

Major Defect:

A single defect in an appliance that can lead to failures and interruptions in operation.

Manager’s Model:

A reasonable number of pieces of equipment handled by smaller groups consisting of front-line leaders (group of leaders) to gain experience and create an informative example through practice with the equipment installed in their own workshop.

Medium Defect:

A single defect in an appliance that may impair its function but allows it to continue operating.

Minor Defect:

A single fault in a device that cannot cause damage on its own, but only leads to damage if a certain combination of these individual faults occurs by chance.

Natural Deterioration:

The deterioration of an item of equipment progresses according to its inherent deterioration characteristics in relation to the passage of time.

One Point Lesson:

A sheet of paper on which only one topic is clearly described; also called the one-topic/one-sheet method.

Overall Inspection:

Inspection includes both broad and specific steps applied to selected categories that are widely used in a facility, such as lubrication, fasteners, transmission, electrical, instrumentation, hydraulics, pneumatics, water, steam, etc. Lubrication is thoroughly inspected in step 3, other general inspection categories are followed up in step 4.

Planned Maintenance:

Activities performed by the maintenance department to maintain and ensure proper equipment operating conditions through careful planning, advance scheduling and preparation after establishing basic equipment conditions (cleaning, lubricating and tightening), repairing defective parts and maximizing parts life.

PQCDSM:

The important features to start and calculate TPM targets and performance; i.e., productivity (P), quality (Q), cost (C), delivery (D), safety (S) and morale (M).

Sporadic Loss:

The gap between the actual effectiveness of the equipment and its optimal value when the recurrence of a particular damage quickly exceeds the usual range of occurrence.

Why-Why Analysis:

Careful monitoring to accurately identify the causes of problems and carefully consider the corrective actions needed to prevent a recurrence of the same problems.

Zero-Oriented Concept:

A certain way of approaching the search for absolute value, the zero point, in human performance and the conditions of equipment, not by way of concrete and actual technical approaches.
