Autonomous maintenance is one of the many tools used during implementation of Total Productive Maintenance and Lean Production in the company. Concept of autonomous maintenance arose from kaizen and 5S principles and its main purpose it to reduce production problems connected with faulty machines, bad maintenance, breakdowns, equipment problems, decrease of equipment effectiveness, etc. It involves training of all production employees to perform basic and common maintenance tasks, such as cleaning, lubricating, inspection, minor repairs, adjustment, calibration, etc.
We distinguish two main topics such as regarding the self issue in the context of a high quality system paying attention only for example on the self-treatment, self-consciousness features and technologies. Another theme concentrates on using autonomous robotics to support, direct and receiving current renovation tasks performed by employees (M. Farnsworth, C. Bell, S. Khan, T. Tomiyama 2015, p. 396).
Autonomous maintenance in 7 steps
"Generally, the AM practice consists of seven steps as the following:
- initial cleaning
- elimination of sources of contamination and hard-to-access areas
- preparation of tentative AM standards
- general inspection
- autonomous standards
- workplace organisation
- all-out AM." (C. S. Min, R. Ahmad, S. Kamaruddin, I. A. Azid 2011, p. 270).
First 5 steps are responsible for decreasing the variation of the equipment length of life. Basically they are for improving the equipmant. In the last 2 steps the most important is improvement the product and design length of life - simply improvement of the process.
Development of Autonomous Maintenance(AM) framework
"The framework focuses on three improvement areas: technical skills, attitude and working culture." (C. S. Min, R. Ahmad, S. Kamaruddin, I. A. Azid 2011, p. 275). The first step concerns autonomous maintenance team creation, time of activity and making a choice which machine to choose. Another step is connected with autonomous maintenance training and motivation. This step contains skills training series. The aim of the skills training series is adding autonomous maintenance to the executive staff training in terms of AM-5 actions.
"The AM-5 activities are as follows:
- initial cleaning
- elimination of sources of contaminations
- establishment of inspection, visual display and control
- establishment of cleaning and lubricating standards
- establishment of AM standards."(C. S. Min, R. Ahmad, S. Kamaruddin, I. A. Azid 2011, p. 278).
The third step referes to the above-mentioned five basic autonomous maintenance activities. In this step particularly important is the way how AM-5 activities are being realised. The last fourth step is deticated to the whole autonomous maintenance audit and constant improvement. The main aim in this fianl step concerns improvement of the practise of autonomous maintenance.
