The 6 major TPM losses are important because they are almost universal in their development and knowing them gives us an excellent starting point to identify and resolve the loss of productivity.
We have already analyzed in another article the characteristics that make TPM or Total Productive Maintenance a holistic, proactive maintenance strategy with the goal of “zero failures.”
This philosophy includes actions that go beyond maintenance, which is why the global TPM (Total Productive Maintenance) strategy is very demanding and often has some setbacks.
What are TPM Losses?
The 6 major TPM losses are based on the OEE (overall equipment effectiveness) indicator . This is a metric that identifies how much of the planned maintenance is fulfilled.
We have developed the metric in another article , but it is linked to the 6 major TPM losses because these, in turn, are based on the 3 factors used to measure the effectiveness of teams in an organization:
Availability : frequency with which the equipment operates.
Performance : How much the equipment produces.
Quality : How many quality items the team produces.
Maintenance losses are classified into six and are linked to these elements.
The process of identifying losses can be iran telegram data carried out under the order and organization provided by professional Maintenance Software .
Regarding availability, there are two common problems: equipment failures and configuration + settings.
- Equipment Failures
This is the loss of availability of our equipment for an unforeseen reason. It may be, for example: a power failure, overheated bearing, motor breakdown, lack of operators or materials, etc.
TPM losses that must be avoided, because it represents a significant time when equipment is scheduled for production, but is not working.
- Machine Settings
One of the reasons we lose productivity is because of machine downtime, either to make adjustments or when something needs to be reconfigured. This is not an emergency or accident, but rather “downtime” of assets.
Some examples of these settings are: schedule settings, cleaning, warm-up time, planned maintenance, and quality inspections.
In relation to performance, two common losses occur: minor stoppages and reduced operating speed.
