xvi Glossary of TPM terms
Refurbishment Plan: Identifying all the activities that need to be undertaken
in order to restore the equipment to 'as new' condition. This includes an
estimate of the cost, manpower resources, agreed priorities, timing and
responsibilities.
Scoping Study: The Scoping Study provides information to support the
development of the TPM implementation programme. This will include a
cost/benefit appraisal. It also identifies any potential roadblocks and provides
an indication of the workforce's perception and feelings.
Set Up and Adjustment Losses: Production time lost because a machine is
being set up or adjusted at the start of a run.
Six Losses: These are the categories of losses the TPM teams use to identify
and measure plant problems so that they can prioritise them and progressively
reduce or eliminate them. These are the things that affect your Overall
Equipment Effectiveness (OEE) score. The six Losses are:
1. Breakdowns
2. Excessive Set Up and Changeover
These two affect whether the machine is available to produce or not. This
is why we use this as the AVAILABILITY percentage within the OEE
calculation
3. Idling and Minor Stops
4. Running at Reduced Speed
These two affect the PERFORMANCE of your machine when running.
This is the percentage rate within the OEE calculation.
5. Reduced Yield (Scrap & Rework)
6. Start Up Loss
These two affect the Quality of the product produced on the machine. This is
the QUALITY percentage within the OEE calculation.
Start Up Loss: Lost production due to defects which occur at the start of a
run.
Support Improvements: Improvements to equipment efficiency that can only
be achieved through changes in other parts of the organization.
Support Team: This team includes representatives from each support function
such as finance, design, engineering, production control, quality control,
supervision, and a Union representative. Usually referred to as Key Contacts.
Technical Improvements: Improvements to equipment efficiency that require
technical analysis of problems before they can be implemented.
TPM: TPM is the abbreviation of Total Productive Maintenance. It is a
comprehensive strategy that supports the purpose of equipment improvement
to maximize its efficiency and product quality. Many TPM practitioners prefer
to call it Total Productive Manufacturing to highlight the need for an equal
partnership between production and maintenance.
