Abstract:

Precision machining of complex industrial parts requires special machines, one of the best of which is the CNC milling machine. Malfunction of machines can cause the production line to stop, while repairs of these machines when they break down without prior possibility and preparation of spare parts with Paying attention to the need to import them is time consuming and costly. In this article, the failure of the device on an annual basis is extracted from the failures recorded in the repair and control sheets of the device, which have been prepared and maintained by the personnel. Then, using Markov chain, to estimate the reliability, maintenance and repair and availability of four-axis CNC milling machine in 2011 was used. The results of implementation in 2011-2018, were compared with the indicators of 2011. The evaluation results show that the availability of the device has increased from 96.3% in 2011 to 99.28% in 2018.
