Total Productive Maitenance - The method as for its scope as well as its efficiency ranks among the most complex and proactive approaches enabling increase of production efficiency. Right setting of the machines and better utilization of its maintenance is a ground precondition for functioning of the whole productive system.
TPM was founded at the beginning of creation of Toyota Production System. The Japan Institute of Plant Maintenance together with the Japan Productivity Centre developed it to its present form.
Hereby a very simple example:
Imagine a bucket filled with water and a couple of cork tops floating on the water level. We can push them down under the water level, but after loosening, they will come up again to the top within a while. Do you get it? Cork tops are like our problems with our production machines, pushing them down under the water level is just like short-term overcoming of our problem that will return to us.
Main principles of TPM are:
- zero rate of unexpected machine downtime
- zero rate of machine breakdown caused by its technical condition
- zero losses caused by slowing down the machine cycle
There are 7 main steps of TPM:
1. Start of cleaning
2. Removal of relevant pollution sources
3. Set up of cleaning standards
4. General check-up
5. Autonomous check-up
6. Organization and systematic cleaning
7. Development of autonomous maintenance
This method can be combined with 5S methodology, SMED and Standardized work method.
